A surface wave travels along the surface of the Earth. It is the slowest of the three types of seismic wave. Surface waves usually have larger amplitude than the other waves and cause the most damage.

which uses "electrical energy . . . as a wave source" that "monitor[s] seismic wave energy" on dry, wet, and frozen diabase samples. Experimentation revealed that the seismic velocities of the dry ...
