... 2. The Earth’s crust is made of fragments called plates and they are slowly moving about the surface. Earthquakes happen most frequently where these plates meet, which is called plate boundaries. When two plates “rub” against one another, they do not move continuously, but instead stress builds up u ...

What Are Seismic Waves?
... There are several different kinds of seismic waves, and they all move in different ways. The two main types of waves are body waves and surface waves. Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthq ...

... What can seismic waves tell us? Studies of the different types of seismic waves can tell us much about the nature of the Earth’s structure. For example, seismologists can use the direction and the difference in the arrival times between P-waves and S-waves to determine the distance to the source o ...

Surface wave inversion
Inversion is the set of methods used to infer properties through physical measurements. Surface wave inversion is the method by which elastic properties, density, and thickness of layers in the subsurface are attained through analysis of surface wavedispersion. The entire inversion process requires the gathering of seismic data, the creation of dispersion curves, and finally the inference of subsurface properties.
