What is a Tsunami?
A giant wave created by an earthquake.
Can a Tsunami happen in Kansas? Why or why not?
No because we aren't located by an ocean.

Surface Waves
The shaking caused by two plates bumping into each other
Earthquake
A measure of the energy that an earthquake releases
Magnitude
Why do tsunami waves get bigger when they reach shallow water?
The wave doesn't fit, so it rises and slows down.
True/False: Earthquakes can be predicted.
False
A tool used to detect and measure earthquake waves.
Seismometer

Where do earthquakes happen?
At plate tectonics
How are Tsunami's created?

Richter Scale
Waves are only half as fast and pass through the solid layers of earth.

6.5
This scale measures only what people feel and damage done by one earthquake.
Mercalli Scale
Spot where the Earthquake starts
Focus
