3.4.1. Body Waves
Body waves characterize seismic activity that travels through the body of the Earth. These waves travel through the Earth's core, as well as the mantle, and help to distinguish the magnitude of an earthquake. The two types of body waves are primary and shear waves, which are defined by their nature. Primary waves, also known as P waves, are the fastest of all seismic waves and can travel through solids and liquids. Shear waves, also known as S waves, can only move through solids and arrive after the primary waves. Both types of waves have a distinguished propagation motion, which is measured and used to determine the magnitude of an earthquake.
