Multichannel Analysis of Surface Waves MASW

The Multichannel Analysis of Surface Waves (MASW) is a seismic method used to evaluate the shearwave velocities of subsurface materials through the analysis of the dispersion properties of Rayleigh surface waves ("ground roll"). The data are collected on the surface without the need of borehole.
