Chapter 5: Earthquakes

This is a rating system that estimates the total energy released y an earthquake.

• The Moment Magnitude Scale

• The Momentum Scale

• The Magnificent Meter Scale

• The Moment Magician Scale

By drawing circles to show distances from three seismograph stations, geologists can locate the _____________________ of an earthquake.

• meter

• epicenter

• focus

• fault

Water displaced by an undersea earthquake may produce _____________________.

• tornados

• fires

• tsunamis

• hurricanes

What type of stress force produces a strike-slip fault?

• shearing

• compression

• liquefaction

• tension

_______________________________ of the crust produces anticlines and synclines.

• seismic waves

• hanging wall

• foot wall

• folding

Compression, tension, and shearing are three types of ________________________.

• movement

• stress

• deformation

• tsunamis

A base-isolated building design ______________________ the amount of energy that reaches the building during an earthquake.

• increases

• reduces

This is used to measure and record ground movements during an earthquake.

• creep meter

• laser-ranging device

• seismograph

• tension

This is the process that occurs when an earthquake's shaking turns loose soil into mud.

• deformation

• shearing

• liquefaction

• base-isolation

The type of stress that pushes masses of rock sideways in opposite directions is ________________________.

• shearing

• tension

• compaction

• P wave
