Question

Define the different types of earthquake waves in detail.

Answer 1

earthquake generate Three Types of seismic waves primary waves and secondary waves .
which arrived at specific recording stations one after another and both primary and secondary waves penetrate the interior of the earth while surface waves do not and due to this primary and secondary waves are known as body waves .

Answer 2

Compressional waves are identical to sound waves – the particle motion is parallel to the propagation direction:

Shear  waves are characterized by particle motion that is perpendicular to the propagation direction:

Surface waves, as the name implies, travel primarily along the ground surface; amplitudes decrease rapidly with depth. There are two typws of surface waves. Like body waves, they are characterized by particle motion.
