Answer:Primary waves, also known as P-waves, travel the fastest and are the first to arrive during earthquakes. P-waves are longitudinal waves that can travel through both solids and liquids, and they cause particles in the ground to vibrate parallel to the direction of wave propagation. As a result, P-waves are able to move through the Earth's interior more quickly than other types of seismic waves.
In addition to P-waves, earthquakes also generate secondary waves (S-waves) and surface waves. S-waves are transverse waves that travel more slowly than P-waves and can only propagate through solid materials. Surface waves, which include Rayleigh waves and Love waves, travel along the Earth's surface and are responsible for much of the ground shaking and damage that occurs during earthquakes.
