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?We use a device that marks the waves of the

earthquake.What does magnitude mean?greatness of size or amount.

Damage Caused by Earthquakes

• tsunamis

“a series of giant waves.”• Aftershocks

Make matters worse. • And unfortunately Death tolls go up

Waves

What are earthquake waves called?Seismic waves

What two types of seismic waves are there?.p waves and s waves.

Body Waves

How do P waves travel?

Travels through solids and liquids

How do S waves travel?. Travels through solids

Which move faster?P waves

GPS Sensors

• One interesting fact about this earthquake is that it moved several GPS sensors. This will require modifications. Japan moved 5 inches closer to the u.s.

• How does elastic rebound explain this movement?

The plates are moving and the plate that japans on moved.

earthquakes

• Scientists are interested in earthquakes I think there deadly and dangerous

• A positive thing about earthquakes is they form mountains and other landforms

• A negative thing about earthquakes is that they destroy

• So earthquakes create and destroy. Wow.
