The point where an earthquake begins

• epicenter

• focus

• fault

• here or there

An earthquake that registered at a 2.1 on the Ricter Scale

• would go unnoticed by most people

• would cause extensive damage to structures such as buildings

• would cause a large tsunami

• there is no such thing as a 2.1 magnitude earthquake

Put the following siesmic waves in order from fastest to slowest A) Secondary waves, B)Primary waves, C)Surface waves

• B,A,C

• C,A,B

• A,C,B

• A,B,C

What causes earthquakes?

• release of energy at plate boundaries (faults)

• the crust moves

• Volcanoes

Which wave is a longitudinal wave?

• S Wave

• P Wave

How can scientists find out where earthquakes occur?

• S and P waves travel at different speeds

• Use the frequency to calculate speed

• compare the time that the different waves arrive

• Use the amplitude
