2. There are
THREE
kinds of
Seismic Waves

3. P-waves
S-waves
L-waves
Types of Wave Movement

4. Each type of wave travels at a constant speed and creates a
different movement
in the Earth's crust.
Animations of Earthquake Waves

5. Studying these waves allows scientists to:
- Determine the amount of energy released by an Earthquake (MAGNITUDE)
- Determine the exact location of the Earthquake
- Create a model of the interior of the Earth
