An earthquake radiates energy in the form of different kinds of seismic waves, whose characteristics reflect the nature of both the rupture and the earth's crust the waves travel through. Determination of an earthquake's magnitude generally involves identifying specific kinds of these waves on a seismogram, and then measuring one or more characteristics of a wave, such as its timing, orientatio… Webrecorded Rayleigh waves (specific type of surface wave) generated using either an active and/or passive acoustic source into a 1-D shear-wave velocity profile of the subsurface. If MASW data are acquired at multiple sites along a traverse, the output 1-D shear wave velocity profiles can be used to generate a 2-D velocity image of the subsurface.

WebSurface wave magnitude, Ms, is measured using the largest amplitude of the surface waves. The general equation has the form: Ms = log (A¦T)+ + 1.66 log (Δ) +3.3. Often the largest amplitude Rayleigh waves are generally at a period of 20s. In this case the general equation becomes: Ms = logA20 + 1.66log (Δ) +2.0. http://eqseis.geosc.psu.edu/cammon/HTML/Classes/IntroQuakes/Notes/earthquake_size.html
