Earthquake Terminology

2. Fault Occurs when the hanging wall of a fault moves down; associated with tensional stress and divergent plate boundaries.
7. A record produced by a seismograph.
8. A destructive mudflow on the slopes of a volcano.
9. Rebound Hypothesis Describes the build-up and release of stress during an earthquake.
10. A sudden shake in the ground from movement within the Earth's crust.
15. The place inside the Earth's crust where an earthquake originates.
16. Wave A seismic wave that travels along or parallel to the Earth's surface.
17. Fault Occurs when the hanging wall and footwall slide past each other; associated with shear stress and transform plant boundaries.

1. The point on the Earth's surface that is vertically above the focus of an earthquake.
3. Fault Occurs when the hanging wall of a fault moves up; associated with compressional stress and convergent plate boundaries.
4. The process of turning something into a liquid, typically a gas.
5. A shear wave that causes particles to vibrate perpendicular to the direction the wave is propagating.
6. A fracture in the Earth that indicates significant movement.
7. Measures and records the details of earthquakes.
11. A long, high sea wave caused by an earthquake or other disturbance.
12. A less severe succeeding earthquake after the main shock of a large earthquake.
13. Also called seismic waves; are the first waves to appear on a seismograph.
14. A mild tremor preceding the shaking movement of an earthquake.
