An earthquake is caused by the movement of tectonic plates, the Earth's crust, and results in violent shaking. The place in the crust where two tectonic plates hit each is the focus, the place directly above the focus on the surface where the quake can be felt is the epicenter. The movement of the plates causes shack waves to spread throughout the Earth. There are two types of waves S and P. The P-waves are the faster of the two and can move through both solids and liquids. S-waves are slower and will reach the surface later, they cannot move through liquids but are easily the most destructive type of wave.
