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.

A new study shows that the inner core changed shape in just a few decades, challenging previous assumptions and revealing ...

There are three types of seismic waves – P waves, S waves and surface waves. P waves are longitudinal waves, and their relative speed is faster than other waves. P waves can travel through ...
