Earth Science - Chapter 12

Most injuries during earthquakes are caused by

The seismic wave that travels through the body of a medium.

A Secondary wave, or transverse wave; this seismic wave is slower and stronger than p-waves

An instrument that records vibrations in the ground.

In the process of elastic rebound, as rock becomes stressed, it first 

Most earthquakes occur 

P waves travel

The point on Earth's Surface directly above an earthquake's starting point. 

Which of the following is not a method used to forecast earthquake risk?

A region of numerous, closely spaced faults.

The location within Earth along a fault at which the first motion of an earthquake occurs.

a movement of the ground that is caused by a sudden release of energy when faults move

A Primary wave, or compression wave. This seismic wave is faster and weaker than other waves.

Earthquakes that cause severe damage are likely to have what characteristic?

Tsunami

A measure of the strength of an earthquake.

The composition of Earth's mantle and core affects

An area on Earth's surface where no direct seismic waves from an earthquake can be detached. 

S waves cannot pass through

The seismic wave that travels along the surface of a medium.

An area along a fault where relatively few earthquakes have occurred. 

Earthquakes generally occur at plate boundaries, where

Vibrations in Earth that are caused by the sudden movement of rock are called

the sudden return of elastically deformed rock to its undeformed shape

A tracing of earthquake motion that is recorded by a seismograph

In Earth science, the amount of damage caused by an earthquake
