PREFACE
UNESCO
This is the second edition of the “Information Guide: Tsunami Early Warning for
Broadcasting Institutions in Indonesia”. The first edition was publised in Bahasa
Indonesia by Jakarta Information Center with support of the United Nations Economic
and Social Commission for Asia and the Pacific (UNESCAP) under a joint project
implemented by UNESCO and the Indonesian Institute of Sciences (LIPI).
In Indonesia, broadcasting companies especially television and radio are an integrated
part of the tsunami early warning system. Therefore, they must fully incorporate the
system as part of their standard operation procedures. Broadcasters are one of the
key links in the warning chain given their responsibility to inform the tsunami early
warning messages directly to the public as quickly as possible.
The tsunami that occurred on the island of Mentawai in 2010, Sendai - Japan in 2011
and north Sumatra in 2012 showed that several of the Indonesia broadcasting company
has taken their role in informing the general public in Indonesia of the potential tsunami
disaster. However, recommendation of the 11 April 2012 tsunami response evaluation
stated that improvement is still needed, especially on the broadcasters’ understanding
of the tsunami early warning messages issued by the Meteorology, Climatology and
Geophysics Agency (BMKG). The guidebook was revised for that purpose and use the
messages issued at the April 2012 as its case study.
We would like to extend our thanks to staff at the Meteorology, Climatology and
Geophysics Agency (BMKG), the Indonesian Institute of Sciences (LIPI), the National
Disaster Management Agency (BNPB), the Communications and Information
Ministry (KEMENKOMINFO), the Indonesian Broadcasting Commission (KPI), German
International Cooperation (GIZ) and representatives of broadcasting companies who
have supported in finalizing the second edition of this guidebook.
We hope this edition will strengthen the role of the broadcasters in Indonesia and
eventually reduce the number of victims and casualties from tsunamis disaster in the
future.

Up until now, the media has tended to focus more on the role it can play in helping
all parties after a natural disaster has occurred whereas, in the time leading up to
a disaster, the public needs useful information on how they should respond to signs
of an impending disaster including, for instance, steps they can take to ensure their
survival in the event of an earthquake that may have the potential to cause a tsunami.
In a situation such as this, the role of the media is crucial. Information about the
natural signs indicating an impending disaster, including official early warnings from
the government via the BMKG, can help the public take precise and swift action in
protecting themselves.
We extend our deep appreciation to the BMKG, the Communications and Information
Ministry, the BNPB and those media colleagues who have already begun to cooperate
closely with disaster management institutions. Indeed, such disasters indirectly make
us aware of the need to support one another and to work together to reduce disaster
risk. The compiling of this book is concrete evidence of this new-found awareness, and
the support from UNESCO in enabling the preparation of this book is in itself a key role.
Reducing disaster risk cannot be achieved without first raising awareness among the
public about disaster preparedness. Community education is a long-term process that
requires consistency from all relevant parties to support it. One manifestation of such
efforts is the formulation of this book. May it prove useful in reducing disaster risk in
Indonesia.
Disaster-prone Indonesia, Let us be Prepared!

BMKG
Tsunami Disaster Risk Reduction (DRR) is a collective responsibility of the central and
local government, communities, and private sector including the mass media.
To implement Tsunami DRR, several efforts need to be done, such as the improvement
of community awareness and preparedness, preparation of evacuation places, and
establishment of early warning. Regarding the latter one, the BMKG is now able to
issue tsunami warnings in 5 minutes after an earthquake occurred. The next step is to
make sure that the communities receive and understand the content of the warning,
and react in the right way to save their lives.
Electronic media, especially television and radio stations play an important role in
disseminating tsunami warnings to communities as well as building awareness and
knowledge about tsunami hazard and the measures to avoid/minimize casualties. This
turns into a significant contribution in the implementation of Tsunami DRR.
The Tsunami Early Warning Information Guidebook for Broadcasting Institutions in
Indonesia, which is a collective effort of a number of institutions and organizations,
is expected to support the media in fulfilling their tasks as part of the dissemination
system for tsunami early warning.
We would like to express our gratitude to UNESCO, JTIC, GIZ-PROTECTS and ESCAP
as well as other parties that have been participating in the development and the
finalization of the guidebook.

The early warning system, as a mechanism for the dissemination of important and
urgent information utilising the latest information technology, needs to be well
managed, integrated and reliable. Television and radio broadcasters with technological
devices play a special and important role in the early warning system by informing the
public about potentially imminent disasters.
TheCommunicationsandInformationMinisterialDecreeNo.20/P/M.KOMINFO/8/2006
on Tsunami Early Warning via broadcasters throughout Indonesia stipulates that “The
media is obliged to broadcast information on a potential disaster as a STOP PRESS item
within the shortest possible time and without delay after receiving the information
from the BMKG”.
This regulation also states that the media has an important role to perform and is an
integral part of the mechanism for disseminating tsunami information to the public. It
is also expected that the media will convey disaster warnings appropriately, accurately
and without interpretation.
Drs. Freddy H Tulung, MUA
Director General for Information and Public Communication

BNPB
The media is one of the links in the early warning chain and is at the forefront of
disseminating information to the public. There are four stages in early warning, namely
understanding disaster risk, monitoring and delivering early warnings, dissemination
and communication, and the response by the public upon receiving early warning
information.
The Operations Control Center (Pusdalops) at the BNPB, which acts as a control center
overseeing coordinated, integrated and unified disaster relief efforts, needs to work
in cooperation with various parties, including the media, so that disaster mitigation
can be implemented quickly, precisely and accurately for the public. It is hoped that
this guide will strengthen the cooperation that already exists between the media and
disaster management agencies in Indonesia.

GIZ IS PROTECTS
Dissemination of tsunami warnings to the communities at risk is still a big challenge
all over Indonesia. From case studies and assessments in communities along the
shorelines of Sumatra, Java and Bali we learned that for many, if not most, people in
the tsunami prone areas the public media is still the most important way to access
tsunami warnings issued by BMKG. Experiences from other countries also confirm the
key role of media in the tsunami warning chain. A very impressing example has been
provided by the Japanese broadcaster NHK during the 3/11 tsunami hitting Japan last
year.
Understanding the importance of media involvement in InaTEWS, we highly welcomed
the initiative by UNESCO and LIPI to develop a handbook for public media at national
level in Indonesia. Therefore we were not hesitating at all to support the publication
of a second edition of the Media Handbook, which was required to accommodate
changes in the warning sequence and products due to the introduction of the new
warning scheme by BMKG in early 2012. Additionally, we jointly agreed to produce
an English language version to make this Handbook available to other countries as a
contribution to exchange experiences and good practices in the region.
We are sure that the Media Handbook will contribute to achieve a better understanding
of InaTEWS and its warning services by all actors involved.

Wearethrilledaboutthereleaseofthisguidebookontsunamiearlywarning.Hopefully,
this guidebook will prove to be very beneficial for the public at large. Disasters often
occur immediately and unexpectedly, anywhere and at any time. And so it is with
natural disasters. Earthquakes, volcanic eruptions, floods, tsunamis, droughts, severe
storms and various other disasters can occur at any moment. And, sadly, such disasters
often cause loss of life.
The number of fatalities in a given disaster varies depending on a number of factors,
including warning information about the impending disaster. Sometimes, the number
of casualties is high because there is no information about the imminent disaster or
there is no way for people to avoid the disaster. In order to reduce loss of life, therefore,
warning information must be disseminated quickly and it must be easily accessible by
the public.
Therefore, we support this initiative of a guidebook that can be used by broadcast
media to disseminate early warning information to the public. Broadcasters have the
wherewithal to make a substantial impact upon the public in Indonesia. Almost all
Indonesians access information via broadcast media stations. Indonesian broadcasts
are easily accessible, inexpensive and can release information quickly to the wider
public. This potential must be utilised as appropriately as possible in the best interests
of the Indonesian people. Broadcasting institutions, whether radio or television
services, need to be aware and socially responsible - especially in the event of natural
disasters and accompanying mitigation efforts - by providing air time for verified
information that can be accessed by the public along with public service advertisement
programmes.
The launch of this book is one of the steps that can be harnessed by broadcast media in
providing tsunami early warning information. We hope that broadcast media stations
will also use the information in this guidebook to provide early warning information
on other natural disasters. Moreover, we hope that broadcast media will participate in
educating the public about the things they need to do when facing a disaster.
We hope this book will be utilised by people throughout Indonesia, but primarily
broadcasting stations.

INTRODUCTION
The Meteorology, Climatology and Geophysics Agency (BMKG) is an institution tasked
with issuing early warning information about tsunamis caused by earthquakes in
Indonesia. Since the official launch of the Indonesia Tsunami Early Warning System
(InaTEWS) on November 11, 2008, the BMKG has continued to develop its capacity and
services in providing tsunami early warnings.
In March 2012 BMKG started to operate the new advanced warning scheme. Now,
the BMKG issues four levels of warning, which are more complete and will help local
governments make decisions that are appropriate to the level of threat affecting their
areas.
Considering conditions in Indonesia, where the threat of a tsunami can occur
in a very short space of time, the tsunami early warning reports issued by the
BMKG must be conveyed to local governments and at-risk communities as quickly
as possible. The BMKG has already established a system that can send out early
warnings very quickly to various relevant institutions including the National
Disaster Management Agency (BNPB), local governments, the Indonesian Military
(TNI), the National Police (Polri) and the media.
The media possesses a unique and very important role. The media’s special quality is
in the speed and breadth of scope with which it can forward tsunami early warning
reports to the public. This fact has already been proven based on a number of natural
disasters both in Indonesia and abroad. Thus, the role of the media is not only to
report the occurrence of a disaster but also to help reducing the number of victims in
a disaster by forwarding early warnings as and when they are received.
This requires that the media needs to alter its orientation from conveying information
about an earthquake to disseminating early warning for the public so that those at risk
can take the necessary action to ensure their safety.
This guidebook has been compiled primarily for use by the media. Its aim is to help
the media distinguish between and understand different types of tsunami warning.
These different warnings are disseminated by the BMKG using various modes of
communication.
This book is structured in five sections. The first section comprises introductions from
the institutions that have collaborated in the production of this guidebook, and the

xii
foreword. The second section offers a blueprint of the course of action that the media
should take in relation to tsunami early warning announcements. The third section
contains examples of the different types of tsunami warning issued by the BMKG
together with explanations how to interprete the information in the media reports. The
fourth section offers concise overview about the tsunami early warning system. The
final section is a reference containing the legal and regulatory foundation upon which
the tsunami early warning system rests. This section ends with a list of relevant experts
and institutions at both national and regional levels. The content of this guidebook
is in based on information publised in the 2nd edition of the InaTEWS Tsunami Early
Warning Service Guidebook, which was published by the BMKG.
Bearing in mind the importance of conveying tsunami early warnings to the public, the
compilers expect this book to become a guide in facilitating the work of the media. To
that end, this guidebook should be placed in broadcasting studios or a similar place
where it can easily be located for the purpose of consultation.
In order to expedite the media’s work at the time of an emergency, every broadcaster
in every institution must participate in regular exercises to develop their attention and
perception.

FOR MASS MEDIA

levels as well as estimated arrival times of the tsunami (information via email/
fax).
• At the moment a TEW-1 or TEW-2 is received, it is not advisable to confirm the
reports directly with the BMKG, considering how busy BMKG staff will be with
analysing and monitoring the imminent tsunami.
• Media personnel are advised to continue giving advice and tips to the public
about how to avoid the tsunami threat, and to continue directing them to remain
calm and follow the directions provided by local government.
• The BMKG will issue a third tsunami early warning (TEW-3) in line with
developments and information it receives. A TEW-3 will contain more accurate
information on the parameters of the earthquake, information from regions
already hit by the tsunami and the latest information on the regional warning
status. TEW-3 messages can be sent out several times in accordance with
updated information on tsunami observation and are marked as follows: TEW-
3.1, TEW-3.2, and so on. An example of a TEW-3 report and its interpretation can
be seen in part “d”.
• When the situation is revealed to be safe from the threat of a tsunami caused
by the earthquake, the BMKG will issue a fourth announcement (TEW-4),
which states that the tsunami early warning has ended. An example of a TEW-4
announcement and its meaning can be found in part “e”.
Notes:
Even after the BMKG issues a TEW-2, there is a possibility that a tsunami will not occur.
In this situation, the BMKG will wait for around two hours following the earthquake
before issuing a TEW-4 announcement, without issuing a TEW-3.
• Start from the symbol labelled “earthquake” on the upper left. The following
steps will be implemented only if appropriate to the given conditions. It must
be remembered that an earthquake may not be physically felt by the media
personnel themselves. The media will know about an earthquake from a BMKG
announcement or from a correspondent in the field. The BMKG will only issue
information about earthquakes that have a magnitude of more than 5 on the
Richter scale (RS). The BMKG will issue an earthquake report or tsunami early
warning within five minutes of the quake occurring.
• At the moment the media receives a report from the BMKG, the first step is to
confirm whether the report consists of “earthquake information” or whether it
is a “tsunami early warning”.
• When the report contains earthquake information and indicating that there is no
tsunami threat, the media can follow up by broadcasting information or running
text across the television screen. An example of this approach and its meaning
can be seen in part “f”.
• When the report is a tsunami early warning, the media must follow up by
presenting a Stop Press news alert, in accordance with legal requirements
that are in force (see section 5, page 79). The presentation of a Stop Press on
television uses information received via the Warning Receiver System (WRS).
This is the first tsunami early warning (TEW-1). An example of a TEW-1 and its
interpretation can be seen in part “a”, while an example of a STOP PRESS alert
can be found in part “b”.
• Furthermore, the media can begin to develop news reports by accessing more
detailed TEW-1 reports via email/fax or the BMKG website. A TEW-1 that is
received via email or fax entails detailed information about the warning status in
the region threatened with a tsunami. There are three levels of warning status,
namely Major Warning (Red), Warning (Orange) and Advisory (Yellow).
• In developing news reports, the media is expected to provide suggestions to
those at risk on how to avoid tsunami hazards. To that end, the media can try
to contact their regional contributors/correspondents in order to ascertain the
directives of local governments.
• While continuing to develop their news reports, it is expected that the media
will continue to monitor for upcoming second-stage tsunami warnings (TEW-
2) issued by the BMKG. An example of a TEW-2 and its meaning can be found
in part “c”. A TEW-2 report offers up-to-date information with more accurate
figures on the earthquake’s parameters, any changes in regional warning status

Tsunami early warning timeline for near field tsunami
From the time an earthquake happens until the tsunami threat ends, the BMKG will
issue four types of warnings:
1. TEW-1: Disseminated based on earthquake parameters and the estimated impact
of the tsunami reflected by warning level (Major Warning - Awas, Warning - Siaga
or Advisory - Waspada) for every affected district.
2. TEW-2: Contains updated earthquake parameters and, in addition to the warning
levels in Warning 1, also the tsunami wave’s estimated time of arrival (ETA) on
shore.
3. TEW-3: Contains tsunami observation information, updated warning levels and
tsunami arrival times, which may be disseminated several times depending on the
tsunami observations at the tide gauge stations, the buoys, the CCTVs, and the
tsunami radars.
4. TEW-4: Announces that tsunami early warning has ended (end of threat).
Following is an explanation of the sequence and types of tsunami early warning
messages that are issued and the expected reaction by local governments and
communities at risk.
T0 – T1: When an earthquake occurs (T0), all the earthquake recording sensors at the
seismic stations around the earthquake source region will record earthquake data
and transmit the data to the NTWC at the BMKG for processing. For earthquakes in
Indonesia, this takes less than 5 minutes (T0-T1).

6
At the BMKG’s NTWC (National Tsunami Warning Center), the automatic seismic-
data processing system calculates earthquake parameters. The SeisComP3
operator then checks the results of the automatic processing and applies
corrections interactively to increase the accuracy of the earthquake’s parameters.
At that time, the earthquake parameters are ready for dissemination and are sent
to the dissemination system as well as to the DSS (Decision Support System). The
DSS will process the data and generates a proposal which has to be reviewed and
confirmed by the DSS operator. The result is either a tsunami warning proposal or
an earthquake information proposal that will be sent by the dissemination system.
If the earthquake is powerful and can be felt very strongly, (or is less powerful but lasts
for a long time), people in risk areas must take immediate action themselves without
waiting for an early warning message.
T1: Dissemination of earthquake information and/or tsunami early warning (T1
≤ 5 minutes). For any earthquake of M ≥ 5 RS, information will be disseminated
simultaneously via SMS, e-mail and fax to local governments, relevant officials and the
owners of mobile phones whose numbers are on the list of recipients for the BMKG’s
earthquake information.
If the earthquake parameters indicate a tsunami threat (an earthquake of M ≥ 7 RS
with a depth of ≤ 100 km and an epicenter located at sea or in coastal areas), Warning
1 is disseminated based on the output of the Decision Support System (DSS), using the
tsunami model in the tsunami database. TEW-1 contains the earthquake parameters
and, if available, information about the estimated impact of the tsunami reflected by a
warning level (Major Warning - Awas, Warning - Siaga or Advisory - Waspada) for every
district that might be affected.
T2: Depending on the warning level, local governments need to react to TEW-1 by
taking the decision whether or not to evacuate and informing the community of the
required action to be taken using the equipment available, such as sounding sirens,
mosque loudspeakers, kentongan (gong-like equipment) and other devices. People
must be able to understand the warning signals and to follow the guidance from the
local government to immediately evacuate to a designated safe location.
T3: TEW-2 is issued to provide updated earthquake parameters and warning levels,
and additional information about the tsunami’s estimated time of arrival on shore.
T4: TEW-3 contains tsunami observation information and updated warning levels,
which may be disseminated several times depending on the tsunami observations
at the tide gauge stations and the buoys.
T5 – T6: The BMKG meanwhile continues to monitor the propagation of the tsunami

T7: TEW- 4: The announcement“The tsunami threat is over” will be disseminated after
the retrieval of supporting data from the tide gauges and/or information from the
community which can confirm there was no subsequent tsunami. TEW-4 will be sent
out at the earliest 2 hours after the announcement of the initial tsunami warning (T1).
The BMKG provides earthquake information and tsunami warnings to BNPB, local
governments and the media. Local governments are responsible for guiding their
communities’ reaction to this information and for deciding whether or not to call for
evacuation.

Tectonic Condition of Indonesia
Indonesia lies on the boundaries of four tectonic plates, which slide
past each other. These four tectonic plates are: the Indo-Australian
Plate to the south, the Pacific Plate to the east, the Eurasian Plate
in the north (where most of Indonesia area lies), and the Philippine
Plate. The figure below shows an illustration of the movement of
these plates. The Indo-Australian Plate moves north, colliding with the
Eurasian Plate. The Pacific Plate moves west, whereas the Eurasian
Plate in relation to the other plate is not moving.
Movement of the main tectonic plates around Indonesia
TSUNAMI EARLY WARNING SYSTEM
IN INDONESIA
The relative movement between these four tectonic plates causes
an accumulation of pressure and mechanical stress where they
collide. When the material’s elasticity is no longer able to withstand
this stress, the rock will break and spring back to something close
to its original shape. This rebound, which generates strong seismic
waves that radiate in all directions along the tectonic plate, is called a
tectonic earthquake.

56
Millions of these earthquakes have occurred over hundreds and
millions of years on the geological time scale. Evidence of these past
earthquakes is recorded in natural geological phenomena (paleo-
seismology). Today, earthquakes can be recorded using seismometer
networks, which calculate an earthquake’s location and focal depth
(hypocenter) and measure its magnitude.
Catgories of tsunami
Tsunamis are classified by distance into two categories:
• Near-field / local tsunamis
Near-field tsunamis are tsunamis that occur within 200 km of the
epicenter of an earthquake. A local tsunami can be caused by
earthquake, landslide, or volcano eruption.
• Far-field tsunamis
A far-field tsunami is a tsunami originating from thousands of
kilometres from the affected areas. Usually starting as a near-field
tsunami that causes extensive destruction near the source, these
waves continue to travel across entire ocean basins with sufficient
energy to cause additional casualties and destruction on shores
more than 1000 km from its source (ITIC, Tsunami Glossary).
The following table shows that the arrival times of tsunamis in
Indonesia are generally between 10 and 60 minutes. This indicates
that these are near field tsunamis.
Since the earth was formed, a number of tsunamis have been
happening all over the world. Paleotsunami research on the west
coast of Sumatra and Thailand indicates that major tsunamis hit Aceh
and Thailand 600 years ago (Yulianto E. and Atwater B., 2008). This
shows that tsunamis occurred in the past and will occur again in the
future.

Tsunami Early Warning System
Early warning is a mechanism which provides advance notice of some
impending event or development of hazards that comes early enough
for you to prepare for it. Early warning can consist of natural signs that
are out of the ordinary. In the event of a tsunami, the first natural
sign is an earthquake that produces either strong ground-shaking or
is perceived as lasting longer but being weaker; thereafter, there may
be a drop in sea levels at the coast for hundreds of metres out to sea
(although this sign does not always occur); a pungent smell of salt
that is out of the ordinary, and so forth. All these things can occur as
indications that a tsunami will strike shortly thereafter.
These natural signs throw up some questions, however:
• Is a tsunami actually going to happen?
• How long until the tsunami arrives on the shore?
• How powerful will the tsunami be?
The fact that these questions remain to be asked means that
natural warning signs are difficult to measure. The best course
of action, if we witness or experience any of the above signs, is to
immediately move away from the coast and make for higher ground.
Unfortunately, natural warning sign are not always clear and people
might misinterpret or miss them, as they will not be able to monitor
for natural signs in every moment.
For that reasons an early warning system is required, as it continuously
monitors and measures the most important precursors to forecast an
impending tsunami threat. It was for that reason that the Indonesia
Tsunami Early Warning System (InaTEWS) was developed. InaTEWS
is the official (and only) tsunami early warning system that exists
in Indonesia, requiring all areas in the country must conform to
the system. In accordance with Law No. 31/2009, only the BMKG is
designated to announce tsunami early warnings. Warning from BMKG
need to be follow by local government disaster management agencies
(BPBD), which are also in charge to develop and implement related
preventative/anticipatory measures.

59
Tsunami Early Warning Chain
The BMKG operates the National Tsunami Warning Center and is the
only government institution appointed and responsible for issuing
tsunami warnings in the Indonesia territory. The warnings have two
aims, namely to trigger evacuations and to mobilize emergency
assistance. Besides tsunamis, the BMKG also provides information
relating to meteorology, climatology and geophysics (seasons,
weather forecasts, earthquakes, air quality, and so on).
The BMKG publishes earthquake and tsunami early warning
information within five minutes of an earthquake occurring, which
is followed by several news updates and/or a news report that the
threat has ended. Early warning messages contain tsunami threat
levels for regencies based on three status levels “Major Warning”,
“Warning” and “Advisory”:
− Wave height ≥ 3 meter resulted in MAJOR WARNING status
− Wave height ≥ 0.5 meter and < 3 meter resulted in WARNING
status
− Wave height < 0.5 meter resulted in ADVISORY status
The BMKG provides earthquake information and tsunami warnings
to BNPB, local governments and the media. Local governments are
responsible for guiding their communities’ reaction to this information
and for deciding whether or not to call for evacuation.
The tsunami early warning communication chain allows for the
dissemination of prompt and effective tsunami early warnings and
guidance. These warnings and guidance are issued by recognised
Early warning is a combination of technology and community
capacity that responds to information provided by the technology.
As a component of disaster risk reduction, early warning requires
not only the production of timely, technically accurate warnings
but also an understanding of risk, a reliable link between providers
and users of warnings and the capacity, on the part of communities
and authorities, to respond appropriately to warnings. A failure in
any one of these elements can mean failure of the whole warning
system.

60
agencies using the agreed channels of communication to allow the
community exposed to the tsunami risk to react appropriately and,
if necessary, to evacuate the area at risk and save themselves before
the tsunami reaches the shore. This chain links the National Tsunami
Early Warning Center to communities at risk along the tsunami-prone
coasts of Indonesia
The agencies that play a role in the InaTEWS tsunami early warning
communication chain are:
• The Meteorological, Climatological and Geophysical Agency
(Badan Meteorologi, Klimatologi dan Geofisika – BMKG),
with its head office in Jakarta, which hosts the National
Tsunami Warning Center,
• Local governments at provincial, district and municipal
levels,
• National and local television and radio stations (public and
commercial),
• The National Disaster Management Agency (Badan Nasional
Penanggulangan Bencana – BNPB),
• The Indonesian Military,
• The National Indonesian Police,
• Communities at risk,
• Cellular service providers,
• Managers of hotels/tourist sites
Detection and Analysis Instruments for Early Warning
InaTEWS has two monitoring systems, namely:
1. Land monitoring system comprising the broadband seismometer
network and GPS
2. Sea monitoring system consisting of tide gauges, buoys, CCTV,
tsunami radar and under-the-sea cable (the last two are currently
at development stage). The observation results are sent to BMKG
mainly using satellite-based communication system.
BMKG operates the network of seismometers, accelerometers, CCTV
and, in the future, tsunami radars. The National Survey and Mapping
Coordination Agency (BAKOSURTANAL/ BIG) operates the network

61
of GPS and tide gauges. The Agency
for the Assessment and Application of
Technology (BPPT) operates the network
of buoys and under-the-sea cable.
The Ministry of Fisheries and Marine
Affairs (KKP) operates tsunami radars.
Until now the tsunami early warning is
issued by BMKG within 5 minutes after
the earthquake based on the network
of broadband seismometers and
accelerometers,combinedwithmodeling
results. In the future, the GPS network
can possibly improve the accuracy of seismic results. Meanwhile the sea
monitoring network is used to confirm the occurrence of tsunami, its
movement as well as its height.
Instruments for earthquake observation
The main instruments of InaTEWS to observe earthquake are the
seismometer network and SeisComP3 software. Both these two
instruments are used to gather and process initial data of earthquake
parameter which serve as the main data to generate tsunami warningsi.
Seismometer network
Morethan90%oftsunamisaretriggeredbystrong,shallowearthquakes.
Therefore, earthquake observation plays the main role in the tsunami
early warning system. However, not all earthquakes trigger tsunamis.
Earthquakes have the potential to trigger tsunamis if they are located
under the sea at a depth of less than 100 km and of a magnitude of 7 or
more on the Richter Scale and are associated with a vertical movement of
the surface of the earth. The last criterion is currently not yet considered
when BMKG issues tsunami warnings.
This is why it is important to determine an earthquake’s parameters
(location, magnitude, and depth) quickly and accurately. This is done by
using seismometers, which are able to measure movements of the earth
by recording seismic waves that are produced when an earthquake
occurs.
Data from several seismometers are processed using special software to
determine the location, time, depth and magnitude of an earthquake.
The denser the network of seismometers, the faster and more accurate
will be the identification of the source of an earthquake. In Indonesia,
the BMKG currently operates 162 seismic stations.
Disain InaTEWS

62
SeisComP3 software
To calculate an earthquake’s location and many other parameters,
special software is used by the BMKG. SeisComp3 has been developed
to process all incoming seismic data and calculate earthquake source
parameters as quickly as possible (Figure 13). The SeisComP3 software
is supported by the JOPEN software as redundant backup system.
The BMKG now has the capability to provide reliable earthquake
information within five minutes after an earthquake has occurred.
Seismic activity is monitored constantly, 24 hours a day, seven days
a week.
If an earthquake of magnitude 5 or greater is located, the BMKG
disseminates earthquake information in several communication
modes, one of which is via short message service (SMS) or text
message (Figure 14). Dissemination of earthquake and tsunami
information will be discussed in Principle 6. Earthquake information
can also be accessed from the BMKG website at www.bmkg.go.id.
Seismometer and Seismogram
Network of seismc stations in Indonesia

63
As explained previously, not all earthquakes trigger tsunami waves.
The criteria for an earthquake capable of triggering a tsunami are:
a. Large magnitude earthquake, usually of M > 7 RS
b. Undersea earthquake with a shallow depth (< 100 km)
c. Deformation or uplift of the sea floor, which is evident from a
normal fault or thrust fault earthquake mechanism
d. Distance from the earthquake epicenter to the shore sufficient
to allow a tsunami wave to form. If an earthquake occurs close
to the shore, the likelihood of it triggering a tsunami is small,
although the impact of the earthquake may be large. The depth
of water plays a pivotal role.
When an earthquake’s parameters match the criteria for an
earthquake that could potentially trigger a tsunami, the earthquake
information will be followed by a tsunami warning. However, even if
an earthquake meets the parameters (location, depth and magnitude)
that could potentially trigger a tsunami, it does not necessarily mean
that a tsunami will occur.
So, a second component of InaTEWS is designed to monitor the
surface of the sea to confirm the formation of a tsunami. Several
instruments are used for this, including buoys, which monitor changes
in the surface of the sea water; tide gauges, which monitor changes in
Screenshoot of SeiscomP3

64
Instruments for tsunami observation
Buoy Network
A buoy is an instrument that measures the height of tsunamis
offshore. It is also known as a tsunameter (Figure 15). It consists of
two separate parts, one of which, called an Ocean Bottom Unit (OBU),
is positioned on the ocean floor. This unit is able to detect changes
in water pressure when a tsunami wave passes. When it detects a
tsunami wave, the OBU sends data to the buoy floating nearby on
the surface. This buoy is the other component of the tsunameter and
measures fluctuations in the level of the water’s surface. It also sends
data from the OBU via satellite to the control center at the BPPT to
be forwarded to the BMKG. In addition, the buoy is fitted with a high-
precision GPS unit, which measures movements on the surface of the
sea and is able to detect passing tsunami waves.
When a tsunami occurs, this instrument will simultaneously record the
tsunami wave and transmit the data. The data from the buoy is used
to determine that a tsunami has been generated. The BPPT operates
the research vessel Baruna Jaya for the installation, maintenance and
relocation of buoys. So far, the buoy system in Indonesia still faces a
lot of challenges in the field.
Tide gauge network
A tide gauge is an instrument for measuring ocean tides. A tsunami
causes an anomalous change on the surface of the sea water, which is
recorded on a tide gauge. This instrument is positioned on the shore
confirming that the tsunami has arrived onshore or that the tsunami
has subsided.
The tide gauges are operated by the National Survey and Mapping
Coordination Agency (BAKOSURTANAL / BIG) but real-time data is also
directed to the BMKG, where the information is analyzed to verify

Tide Gauge Stations
CCTV Network
CCTV (Closed Circuit Television) is a digital video camera that is used
to send signals to a display monitor in a room or predetermined place.
CCTV is often used to observe public areas, such as train stations,
roads, town squares, shops and buses, banks, hotels, airports, military
storerooms, factories and warehouses. Nowadays, CCTV is also used
to protect people’s homes.

66
Radar Tsunami
InaTEWS uses CCTV to monitor the arrival of a tsunami. Once CCTV
has been fitted in areas exposed to tsunamis, an incoming tsunami
can be detected by pictures that are sent real time. Currently, five
online CCTV cameras have been installed, which send pictures to
the Tsunami Early Warning Center in Jakarta. Four of these cameras
are located in Bali at Benoa Beach, Kuta Beach, Sanur Beach and
Seminyak, while the fifth camera is in Simpang Layang, Banda Aceh

Radar Tsunami
While preparing this document, the tsunami radar is not yet a part of
InaTEWS. In 2013, it is planned to have the tsunami radars installed
in Banten (2), Bali (1) and West Sumatra (1). Tsunami radar is an
equipmentsystemthathasthecapacitytodetectthearrivaloftsunami
starting the distance of 150km from and approaching the coast. The
radar, which transmits high frequency (HF) electromagnetic wave, will
surely improve the accuracy and speed of InaTEWS’ confirmation on
tsunami occurrence.

67
GPS Station
GPS Network
A GPS, or Global Positioning System, is a system for determining an
exact position on earth, expressed as longitude, latitude and height.
By placing a GPS device at a point on the earth’s surface, the exact
position will be determined. Changes to that position are recorded
constantly. Rapid changes in the position are then transformed
into relative movement vectors, from which deformation of the
earth’s surface can be detected and displayed. A GPS can provide
useful information to scientists about the relative movement of
tectonic plates and can support the analysis of plate movements to
determine whether they have the potential to create earthquakes.
A GPS also measures changes in the position of the earth’s plates
after an earthquake occurred. The GPS stations are also operated by
BAKOSURTANAL / BIG.
Processing and analysis - Decision Support System (DSS)
Aside from the SeisComP3 software, another instrument being used
in InaTEWS is the Decision Support System (DSS). DSS is a computer
system that assists operators at the National Tsunami Warning Centre
in issuing an accurate tsunami early warning in a very short period of
time, and also assists them in advising on the affected areas, level of
warning and arrival times.
DSS – Decision Support System
As explained previously, the SeisComP3 software is used to process
data from seismometersto determine earthquake parameter in a
quick time, while for the following analysis BMKG applies another
software, which is called the Decision Support System (DSS).
The DSS aggregates all the information from the sensor groups to
evaluate whether or not a tsunami has been generated. To assess
which areas will be affected, and to determine the respective warning
levels, a simulation system with pre-calculated scenarios is used.
The simulation system compares the incoming data from the sensor
network with the scenarios stored in a database. The system selects

68
the scenarios with the best match and provides the officer on duty
with information on the expected travel times of the tsunami waves,
the affected areas and the expected wave heights on the coast.
The DSS shows information on four monitor screens:
The Decision Support System is activated upon receiving the
earthquake parameters sent by SeisComP3 containing information
on location (latitude, longitude, depth) and earthquake magnitude.
The location of the epicenter will determine what happens next.
If the epicenter is in Indian Ocean ranging from the southwest of
Sumatera, via the south of Java to the south of Sumbawa, the DSS will
compare the parameters with the existing tsunami database. If the
epicenter is at a different location, it will use EasyWave (a real-time
estimation software) to create a tsunami threat scenario if the criteria
of earthquake with potential for tsunami are met. The result of the
DSS is a proposal with two possibilities, namely:
a. “Tsunami warning proposal” if the DSS provides a scenario of
tsunami occurrence based on modeling and estimation results.
There will be a map and a list of areas with tsunami potential
along with level of warning and estimated times of arrival.
b. “Earthquake information proposal” if the DSS identifies the
earthquake as not having the potential to trigger a tsunami.
The DSS operator will then send the proposal further to the
dissemination system. It is the dissemination officer that spreads the
tsunami warning proposal or the earthquake information proposal
after verifying the content of the information.

69
The first screen is the situation perspective of the geographical situation and timeline.
A map shows the expected propagation of the tsunami waves according to a pre-
calculated scenario, and also indicates the location of buoys and tide gauges that are
in the range of the tsunami waves
A second screen provides more detailed information from incoming measurements of
the different sensors as well as simulation data

An evaluation of the situation is displayed on a third screen. The DSS assigns a
warning level for each of the affected districts and proposes options for decision
making
Besides the dissemination control buttons, the fourth screen provides a summary of
the warning and a preview of the warning messages

71
Modes of Dissemination of Early Warning Messages
The media will receive earthquake information and tsunami early
warnings from the BMKG via various modes of communication. These
comprise:
1. Warning Receiver System-WRS
2. Fax
3. E-mail
4. SMS
5. BMKG Website
Warning Receiver System
Receiving information via the Warning Receiver System (WRS) is
prioritised for television broadcasters, and for those who have
already installed the application from the BMKG. Television media
will get a message via this application consisting of a map image
and the parameters of the quake that has occurred. Radio stations
that are interested in acquiring this application can submit a request
(according to certain requirements) to the BMKG (hotline number:
021-6546316 or tel/fax: 021-65867045).
Fax
Earthquake information and tsunami early warnings can also be
received via fax with a long-sentence format. Only certain groups
receive faxed information; the total number of fax recipients is far
smaller than those receiving information via SMS. The contents of
fax information are the same as for E-mails. Prioritised recipients
are those involved in disaster management and decision-makers at
national and local levels (Relevant institutions, Governors, Regents,
Mayors, Police, Military, Pusdalops, experts etc.
E-mail
If there is an earthquake with a magnitude greater than 5 RS and
tsunami warning information, the warning system at the BMKG will
send the warning information to those individuals and agencies whose
e-mail addresses are registered with the BMKG. The information is
sent to those involved in disaster management and decision-makers
at national and local levels (Governors, Regents, Mayors, Police,
Military, Pusdalops, experts etc).

72
SMS
SMS messages are sent out for all earthquakes with a magnitude
greater than 5 RS and state whether there is a tsunami threat.
Earthquake and Tsunami Warning Information is sent to mobile phone
numbers that are registered in the BMKG’s database, which allows for
a limited number.
BMKG Website
The BMKG offers a broad service to the general public via its website
(www.bmkg.go.id), so that people can be informed of earthquakes
and tsunami threats. Besides that, the website also offers the public
additional information, such as weather forecasts, sea levels, floods,
etc.
Radio and television stations that want to receive tsunami early
warning information via e-mail, fax and SMS must register their
telephone and fax numbers, and e-mail addresses with the BMKG.
The website is available for anyone who has an Internet connection.

73
Format of InaTEWS Tsunami Early Warning Messages
There are three formats of tsunami warning messages: short-text
format (text message/SMS), long-text format (fax, e-mail and GTS)
and media format (website and WRS).
1. Short-text format.
Used to disseminate warnings via text message (SMS). The
number of characters is limited to 160.
2. Long-text format.
Contains more complete information and is disseminated via
e-mail, fax and GTS. The outline
of the long-text format includes:
a. Header, indicating the source of the information, i.e., the BMKG
as the official provider ofwarning messages under InaTEWS.
b. Information content, which consists of three components:
i. First, the earthquake parameters
ii. Second, tsunami observation data, if already available
iii. Third, the warning level, estimated tsunami arrival time,
and affected locations.
c. Advice, containing recommendations to local governments
regarding the appropriate response
3. WRS format for interface institutions and the media
Contains information regarding EQ parameters, tsunami threat,
affected areas, warning levels and estimated time of arrival.
It also includes a map indicating the EQ location. The format is
designed to be displayed on monitor screens and has a graphic
user interface. Additionally, a special graphic is provided to TV
media.
4. Website format
BMKG website (www.bmkg.go.id) displays information on
earthquake (date and time) and provinces with tsunami potential.

74
Roles and Responsibilities of Institutions and Communi-
ties in the Tsunami Early Warning Communication Chain
The tsunami early warning communication chain allows for the
dissemination of prompt and effective tsunami early warnings and
guidance. These warnings and guidance are issued by recognised
agencies using the agreed channels of communication to allow the
community exposed to the tsunami risk to react appropriately and,
if necessary, to evacuate the area at risk and save themselves before
the tsunami reaches the shore. This chain links the National Tsunami
Early Warning Center to communities at risk along the tsunami-prone
coasts of Indonesia.
The agencies that play a role in the InaTEWS tsunami early warning
communication chain are:
- The Meteorological, Climatological and Geophysical Agency
(Badan Meteorologi, Klimatologi dan Geofisika – BMKG), with its
head office in Jakarta, which hosts the National Tsunami Warning
Center
- Local governments at provincial, district and municipal levels
- National and local television and radio stations (public and
commercial)
- The National Disaster Management Agency (Badan Nasional
Penanggulangan Bencana – BNPB)
- The Indonesian Military
- The National Indonesian Police
- Communities at risks
- Cellular service providers,
- Managers of hotels/tourist sites
These institutions that play a role in the early warning chain are
obliged to immediately confirm (manually) that they have received
early warning messages sent by BMKG.
Each of these institutions has specific roles and responsibilities in the
tsunami early warning communication chain.

75
The National Tsunami Warning Center (NTWC) at the BMKG Head
Office
The NTWC is the provider of tsunami early warnings in Indonesia. The
BMKG provides information on earthquakes, tsunami early warnings
and advice on reaction in areas exposed to tsunami risk and to other
actors in the tsunami early warning communication chain.
The BNPB
The BNPB is required to follow up on earthquake information and
tsunami early warnings and advice received from the BMKG. The BNPB
supports the dissemination of tsunami early warnings and advice to
local disaster management institutions. The BNPB is also responsible
for the preparation of an appropriate emergency response (search
and rescue and assistance on land) as soon as the tsunami threat has
passed.
Local governments
Local governments are required to act on earthquake information
and tsunami early warnings and advice issued by the BMKG.
Local government is the only actor in the tsunami early warning
communication chain that has the authority and responsibility to
make the decision on, and to officially announce, an evacuation
status based on information from the BMKG. Pursuant to Articles
46 and 47 of Law 24/2007, Article 19 of Government Regulation
21/2008, and Chapter 2 of the Decree by the Head of the BNPB
3/2008, local governments are responsible for issuing immediate
public announcements containing clear directions and instructions
to help the inhabitants of, and visitors to, an area react quickly and
appropriately to a tsunami threat.
The Indonesian Military
The Indonesian Military is required to follow up on earthquake
information and tsunami early warnings and advice received from the
BMKG.Themilitaryhasaroleindisseminatingearthquakeinformation
and tsunami early warnings at the local level. If an evacuation is
announced, the military can help to evacuate people. The military is
required to make preparations for an emergency response (search
passed.

76
The National Indonesian Police
The Indonesian Police are required to follow up on earthquake
information and tsunami early warnings and advice received from
BMKG. The police have a role in disseminating earthquake information
and tsunami early warnings at the local level. If an evacuation is
announced, the police can help to evacuate people. The police are
required to make preparations for an emergency response (search
passed.
Television and radio stations
National and local television and radio stations (commercial and
public) are required to broadcast earthquake information and tsunami
early warnings from the NTWC and guidance from local government,
pursuant to Article 34 of Law 31/2009 and Articles 1 to 6 of the
Decree by the Minister of Communications and Information 20/2006.
Television and radio stations form the actor in the tsunami early
warning communication chain that has direct, rapid and nationwide
access to the public. Television and radio stations are required to
immediately interrupt programs to broadcast tsunami early warnings
and advice from the NTWC to viewers and listeners.
Communities at risk
Masyarakat berisiko berhak mendapatkan informasi tentang
ancaman tsunami serta arahan instruktif yang memungkinkan orang-
orang yang terancam bencana bertindak secara tepat dan cepat.
Masyarakat bertanggung jawab untuk siap menyelamatkan diri dari
ancaman gempabumi dan tsunami. Individu dan lembaga masyarakat
wajib meneruskan informasi serta arahan yang benar kepada orang
lain. Lembaga Swadaya Masyarakat seperti Organisasi Amatir Radio
Indonesia (ORARI), Radio Antar Penduduk Indonesia (RAPI) dan
Search and Rescue (SAR) ikut beperan dalam penyebaran informasi
gempabumi, peringatan dini tsunami, serta saran yang disampaikan
oleh BMKG.
Cellular service providers
Cellular service providers comprise one part of the earthquake
information and tsunami early warning dissemination chain using the
mode of short message service (SMS). Cellular service providers are

77
obliged to forward information on earthquakes and tsunami early
warnings from the BMKG to the selected and previously registered
handphone users. These cellular service providers give higher priority
to the delivery of SMS from the BMKG as opposed to general SMS,
such as individual/personal SMS. In a situation where the traffic of
SMS message is high, SMS-es from the BMKG are given precedence in
the queue for sending to registered users. In addition, cellular service
providers must keep their service operating in good condition. All
these services are provided free of charge.
Hotel managers
The managers of hotels are obliged to protect the guests staying in
their hotels,visitors to their hotels and are encouraged to care for the
members of the public located around the hotels. Hotel managers
have the responsibility to prepare all procedures and action plans
for earthquake and tsunami emergencies via the following steps:
create a receiving mechanism for early warnings from the BMKG,
Pusdalops or the BPBD; provide complete information to guests on
the steps that must be taken in the event of a tsunami emergency;
prepare a temporary evacuation site together with evacuation route
signs both inside and outside the hotel building. (If evacuating inside,
a hotel must meet the requirements of earthquake- and tsunami-
resistant structures and it must be on higher ground than the
estimated height of tsunami waves in the given area). When hotel
guests have to evacuate to a place outside the hotel, the manager is
obliged to provide guests with detailed information on the location
of the temporary evacuation site and he/she must guide them to the
evacuation site at the time of a tsunami emergency.
