Basic Background Information

What is an earthquake?

a series of vibrations induced in the earth's crust by the abrupt rupture and rebound of rocks in which elastic strain has been slowly accumulating.

How are earthquakes measured? The moment mangtitude scale.

What is magnitude Magnitude is the total energy released.How is magnitude measured? Magnitude by using the semsic

waves.Type your answer here.

Damage Caused by Earthquakes

• Type one type of damage here.Landslides building collapse tsunamis

• Type one type of damage here.

• That tsunamis can happen after a earthquake high magnitudes.

• Type one type of damage here.

• It can collaspe bulidings.

• Type one type of damage here.

Waves

What are earthquake waves called?

When a sudden break or shift occurs in the earth's crust, the energy radiates out as seismic waves

What two types of seismic waves are there?

Body and surface waves.

What two types of body waves are there?primary and secondary waves.

here.

.

Body Waves

How do P waves travel?Travel 1 to 5 miles per second depending on what on material there have to move throught.

How do S waves travel?They log little behind P-wavesWhich move faster?Primary move faster

Elastic Rebound

Replace these directions with your description of elastic rebound.

You may also insert images or an animation to help explain.

In what type of plate boundary does elastic rebound occur?

The Tohoku Earthquake

This quake occurred at :

Near the coast of Honshu, Japan

This quake occurred Between the plate boundary of north pacific and pacific

The magnitude of this quake was an 9.0
