What direction do the three different seismic waves travel?

Answer 1

Actually, there are four main types of seismic waves.

All of them involve contractions in some direction. Generally, the impact can be felt in all directions, but you can take a look at the above image for reference as to whatever causes the seismic wave.

The three different seismic waves, primary (P-waves), secondary (S-waves), and surface waves, travel in different directions. P-waves travel through solids, liquids, and gases and travel in the same direction as the wave is moving. S-waves travel only through solids and move perpendicular to the direction of wave propagation. Surface waves travel along the Earth's surface, causing the ground to move in a rolling motion similar to ocean waves.
