Discussion of MS magnitude computation

Accordingly, for shallow seismic events of the same magnitude, surface waves have generally larger amplitudes than body waves; surface wave amplitudes change smoothly with distance. They generally decay up to a ...

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.
