A disturbance like an earthquake at any point on the Earth will produce energetic waves called seismic waves. The Earth's crust as a solid object will support waves through the crust called body waves and on the surface (surface waves). In a solid material these waves can be either longitudinal waves or transverse waves. read more
Seismic waves are example of longitudinal waves. Longitudinal waves are waves in which the displacement of the medium is in the same directionas, or the opposite direction to, the direction of propagation of the wave. read more
For seismic waves through the bulk material the longitudinal or compressional waves are called P waves (for "primary" waves) whereas the transverse waves are callled S waves ("secondary" waves). Since any material, solid or liquid (fluid) is subject to compression, the P waves can travel through any kind of material. read more
Seismic waves are waves that are a result of What are Seismic Waves activity in the earth. There are body and surface waves. Body waves happen inside the earth and are called P (longitudinal) and S (transverse) waves. Surface waves happen on the earths surface and are called Raleigh and love waves. read more
