7. What do you think caused this?

8. Rocks move along faults  Most faults are located along tectonic plate boundaries.  Very little movement actually happens during an earthquake.  Earthquake belt: 80% of earthquakes happen here  Around the Pacific Ocean  San Andreas fault  North American Plate & Pacific Plate come together  In California  Earthquakes occur in the lithosphere

10. How Faults are Classified  3 types of faults  Normal fault  Reverse fault  Strike-slip fault  Faults are named based off of how rock moves

11. Normal Faults  Stress that pulls rocks apart is what causes this fault.  Tension forces  Footwall moves upward  Hanging wall moves downward

12. Reverse Faults  Caused by rock being pushed together  Compression forces  Footwall moves downward  Hanging wall moves upward

13. Strike-Slip Fault  Rocks move side by side  Caused by shearing forces

14. So how do we get an earthquake?  Pressure is applied to rocks  Rocks bend and stretch  Rocks exceed their elastic limit  Rocks break, causing an earthquake
