1. Earthquake Foldable

2. Earthquake =
Vibrations and shaking caused by two tectonic plates sliding past each other.

3. Reverse Fault Draw a picture of a reverse fault.
Definition: A fault in which the rock above the fault plane (hanging wall) is displaced upward.

4. Normal Fault Draw a picture of a normal fault.
Definition: A geological fault in which the hanging wall has moved down.

5. Strike-Slip Fault Draw a picture of a strike-slip fault.
Definition: A fault in which surfaces on either side of the fault plane have moved horizontally and parallel to the fault line with little up or down movement.

6. Other Terms
Epicenter: The point on Earth’s surface directly above the focus of an earthquake.
Focus: The point of origin of an earthquake.
Primary (P) Waves: a wave in which rock particles vibrate parallel to wave travel; can go through liquids and solids.
Secondary (S) Waves: a wave in which rock particles vibrate at a right angle to wave travel; cannot go through liquids.
Surface Waves: a wave that travels across the surface of earth (not in it); slower/larger amplitudes (loud), longer wavelengths.
