Chapter 6 Review: Earthquakes

A portion of Earth that does not receive any seismic waves from a particular earthquake

An instrument used to record and measure ground movements caused by seismic waves

The point on Earth's surface directly above the focus of an earthquake

The rupture and sudden movement of rocks along a fault

A fracture surface along which rocks on either side of the fracture move

A record of the seismic waves created by a seismograph

A process by which shaking makes loose sediment behave like a liquid

An ocean wave caused by an earthquake, sometimes called a seismic sea wave

Seismic waves created when some of the energy from P-waves and S-waves reach Earth's surface 

A wave of energy produced at the focus of an earthquake as elastic strain is released 

A measurement of either the size of the waves produced or the energy released by an earthquake

The first magnitude scale, published by a seismologist from southern California in 1935

The most widely used modern scale for measuring the energy released by an earthquake

The sudden movement of soil and rocks down a slope

A value that describes the effect of an earthquake in a particular area

A scientist who studies earthquakes

The energy of motion

Energy stored in rocks as a change in shape

Compressional seismic waves that move rocks and mater in the same direction as the wave travels

The place on a fault where the rupture and movement of an earthquake begins

Shearing seismic waves that move rocks in a perpendicular from traveling waves

Large, brittle pieces of Earth's outer shell

An abbreviation often used for secondary waves

An abbreviation often used for primary waves

Process used to locate the epicenter of an earthquake using data from three or more seismograms
