Earthquake Seismic Waves and Destructions Review

The magnitude of an earthquake measures...

• the amount of energy released.
• the amount of time the earthquake lasted.
• the depth at which the earthquake occurred.
• the temperature of the magma below the epicenter.

• 2
• 3
• 1 billion

Liquefaction is when...

• the soil behaves like liquid.
• the ground becomes liquid.
• magma rises to the surface.
• buildings are damaged, crumbling like liquid.

A type of seismic wave that causes particles of rock to move in the same direction as the wave movement.

• Love
• P- wave
• S- wave
• Rayleigh

You use a P- and S- wave travel-time graph to find:

• distance from seismic station to epicenter.
• distance from fault to epicenter.
• distance from epicenter to core.
• distance from seismic station to focus. 

This is the area beneath the Earth's surface where the earthquake begins.

• epicenter
• focus
• fault line
• tectonic plate

• electromagnetic waves.
• seismic waves.
• gravity waves.
• chemical energy.
