At type of seismic wave only travels on the earth surface
1 answer
The type of seismic wave that only travels on the Earth's surface is called a surface wave. Surface waves are slower than body waves, which travel through the Earth's interior. There are two types of surface waves: Love waves and Rayleigh waves. Love waves move side to side and are responsible for much of the horizontal shaking during an earthquake. Rayleigh waves move in an elliptical motion and cause both vertical and horizontal ground movements.
