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
