Masw
The standard MASW approach is based on the personal (i.e. subjective) interpretation of the phase-velocity spectrum of the vertical component of Rayleigh waves. This way, we do not invert the actual datum but a subjective interpretation that can be wrong and lead to erroneous shear-wave velocity (Vs) profiles.Método MASW.

MASW starts by acquiring data that reflects the changes surface waves experience while propagating across and area of concern. Data acquisition is fairly straight forward. One simply records variations of ambient noise (passive survey) from cars, trucks, trains, and other or from a maned seismic source (active survey).MASW Survey - Handbook Park Seismic LLC 9 2.
