The first waves to arrive are P-waves, followed by S-waves, two types of body waves.

WebEarthquakes occur because stresses build up between the plates as one plate passes another. As the plates move past one another they don't do so smoothly, rather, they snag and grind, allowing energy to build up. When the plates eventually move again this energy is released as shock or seismic waves through the Earth's crust.
