Q

What is the epicenter of an earthquake?

A

An earthquake’s epicenter is where the seismic waves reach the surface.

2
Q

What are the three types of seismic waves?

A
  1. P waves
  2. S waves
  3. Surface waves
3
Q

Describe P waves

A

P waves are the primary seismic waves, and are the first to arrive. They shake the ground from side to side.

4
Q

Describe S waves

A

S waves are the secondary seismic waves, and arrive second. They shake the ground both side to side and up and down. S waves can’t move through liquids.

5
Q

Describe surface waves

A

Surface waves are what some P and S waves become when they reach the surface. They move slower than P and S waves, but can be more destructive. Surface waves make the ground roll in a wavelike motion.

6
Q

What are seismic waves?

A

Seismic waves are energy waves that come from the center, or focus of an earthquake.
