5. Nearly vertical with
minimal inclination from
the horizontal
Direction of Slip:
Horizontal motion,
where two tectonic plates
slide past each other
horizontally
Inclined at an angle
greater than 45
degrees from the
horizontal
where hanging wall moves
upward relative to the
footwall that typically
form in compressional
tectonic settings.
Inclined at an angle less
than 45
degrees from the
horizontal
Direction of Slip: Vertical
motion, where hanging wall
moves downward relative to
the footwall that occurs
from tensional tectonic
settings.
6. Play the news about the magnitude 7.4 earthquake that
happened in Surigao Del Sur last December 2, 2023.

After watching the video clip, ask the learners the
following questions:
What did you observe in the video?
Who among you have experienced an earthquake?
What are the things that can happen during an earthquake?
Are you familiar with the fault lines in the Philippines
7. WORD PUZZLES
The learners will look for the following words inside the
puzzle.
It could be horizontal, vertical, diagonal, or reverse.
1. FOCUS
2. EPICENTER
3. MAGNITUDE
4. INTENSITY
5. WAVE
8. 1. FOCUS. The point within Earth where rock under stress breaks, resulting in
an earthquake.
2. EPICENTER. The point on the Earth's surface that is directly above the
focus.
3. MAGNITUDE. Earthquake magnitude is a measure of the “size,” or
amplitude, of the seismic waves generated by an earthquake source and
recorded by seismographs (instrument that makes a record of seismic waves
caused by an earthquake, explosion, or other Earth-shaking phenomenon).
4. INTENSITY. It is a measure of the strength of shaking experienced in an
earthquake.
5. SEISMIC WAVE. The vibration generated by an earthquake, explosion, or
similar energetic source and propagated within the earth or along its surface.
