They are typically generated when the source of the earthquake is close to the Earth's surface. Although surface waves travel more slowly than S-waves, they can be much larger in amplitude and can be the most destructive type of seismic wave.

They are commonly created when the wellspring of the seismic tremor is near the Earth's surface.
Albeit surface waves travel more gradually than S-waves, they can be a lot bigger in sufficiency and can be the most dangerous kind of seismic wave.
When a tremor happens, the shockwaves of discharged vitality that shake the Earth and incidentally turn delicate stores, for example, dirt, into jam (liquefaction) are called seismic waves, from the Greek 'seismos' signifying 'quake'.
Seismic waves are normally created by developments of the Earth's structural plates yet may likewise be brought about by blasts, volcanoes and avalanches.
