Kortz and Jessica J. Smay Version: 10 July 2019
- 2. EARTHQUAKE DAMAGE: HAITI, 2010 Author: Marco Dormino/ The United Nations
- 4. EARTHQUAKES HAPPEN ALONG PLATE BOUNDARIES Author: Phoenix7777. Data source: Search Earthquake Archives, USGS
- 5. ELASTIC REBOUND THEORY • Moving plates are stuck along faults at their boundaries because of friction; stress builds up in bedrock • An earthquake happens when the stress is too much and overcomes the friction plates move stuck from friction stress builds fault moves during earthquake Author Bumfluff at English Wikipedia
- 6. ELASTIC REBOUND THEORY • Animation from IRIS: https://www.iris.edu/hq/inclass/animation/ela stic_rebound_on_highfriction_strikeslip_fault Author IRIS • Animation from IRIS: https://www.iris.edu/hq/inclass/animation/ela stic_rebound_on_highfriction_strikeslip_fault
- 7. MEASURING GROUND MOVEMENT • Brainstorm how scientists can measure plate movement
- 8. MEASURING PLATE MOVEMENT GPS Station VDCY in Southern California • In the following activities, you will learn how GPS stations like this one continuously measure the changing position of the ground near plate boundaries
- 9. Data for 2.1
