What do you think caused this?
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
San Andreas Fault
How Faults are Classified
3 types of faults Normal fault Reverse fault Strike-slip fault
Faults are named based off of how rock moves
Normal Faults
Stress that pulls rocks apart is what causes this fault. Tension forces
Footwall moves upward
Hanging wall moves downward
Reverse Faults
Caused by rock being pushed together Compression forces
Footwall moves downward
Hanging wall moves upward
Strike-Slip Fault
Rocks move side by side
Caused by shearing forces
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
