A seismic wave is an elastic wave that causes a sudden disturbance in earth materials.

• Seismic waves are both longitudinal and transverse waves.
• There are two main types of seismic waves which are the surface and body waves.
• The surface waves runs on the earth surface. These are the rayleigh and love waves.
• The surface waves causes damages on the earth surface as they are both longitudinal and transverse.
