2. Earthquakes 1 Presented by: Anjela Lu B. Arellano https://www.tumblr.com/search/earthquake+gifs

3. What are Earthquakes? Violent shaking of the ground Destructive phenomenon https://www.tumblr.com/search/earthquake+gifs

4. What causes Earthquakes? Active Volcanoes (Volcanic quakes) Outside influences (Induced quakes) Shifting of Tectonic plates Slip on a Fault https://www.tumblr.com/search/earthquake+gifs

5. Slip Relative displacement Adjacent points Opposite sides of fault www.wikipedia.com

6. Fault Break Movement takes place o Fault Plane Fracture surface o Fault line or Fault trace Intersection Fault plane and Ground surface www.sciencebuzz.org http://geomaps.wr.usgs.gov.html

7. Different types of Fault Normal Faulting – Crust is pulled apart Reverse faulting – Crust is being compressed Strike-slip – Crust moves sideways Oblique slip – Various combinations http://www.iris.edu

8. Tectonic plates Also called: Lithospheric Plate Irregular shape Composition: Continental & Oceanic lithosphere https://www.tumblr.com/search/earthquake+gifs www.science.taskermilward.org.uk

9. Stress Force applied to an objectTypes of stress: Confining – Deeply buried rock is pushed down Compression – Squeezed together – Fractures and folds Tension – Pulled apart Shear – Parallel – Opposite directions http://www.iris.edu

10. Seismic waves Waves of energy Recorded in seismograph http://sciencelearn.org.nz

11. Types of Seismic waves Body Waves – Travel through Earth’s inner layers Surface Waves – Travel through crust http://www.iris.edu

12. Creep vs. Major Earthquake Creep: Slow and continuous movement Major earthquake: Sudden slip on a fault http://www.iris.edu/hq/programs/education_and_outreach/animations/10 https://www.tumblr.com/search/earthquake+gifs http://earthquake.usgs.gov/learn/topics/creep/

13. Foreshock, Mainshock & Aftershock Foreshock – smaller earthquake Mainshock – Greatest magnitude Aftershock – Continue after mainshock http://www.iris.edu
