Earthquakes generate three types of seismic waves: P (primary) waves, S (secondary) waves and surface waves, which arrive at seismic recording stations one after another. Both P and S waves penetrate the interior of the Earth while surface waves do not. Due to this, P and S waves are known as body waves.
There are three basic types of seismic waves â P-waves4, S-waves5 and surface waves. P-waves and S-waves are sometimes collectively called body waves. P-waves, also known as primary waves or pressure waves, travel at the greatest velocity6 through the Earth. When they travel through air, they take the form of sound waves â they travel at the speed of sound (330 ms-1) through air but may travel at 5000 ms-1 in granite7. Because of their speed, they are the first waves to be recorded by a seismograph8 during an earthquake.
