Question

Difference between body waves and surface waves of earthquake

Answer 1

Body wave travels inner layer of the earth and the surface wave travels across the earth surface

Answer 2

Answer:

• Body waves are traveling through the Earth's interior. On the other side, surface waves propagate only at the ‘interface between’ two distinct media, such as the Earth-atmosphere interface (i.e. Earth's ground).

• There are two different kinds of body waves: ‘primary waves’ and ‘secondary waves’.

• Primary waves usually referred to as P-waves or pressure waves and secondary waves usually referred to as S- waves.

• They can spread in material that is solid or liquid. ‘S-waves’ are waves of shear. Only in strong material they propagate.
