What is MASW?

MASW (Multichannel Analysis of Surface Waves) is a geophysical method used to determine the shear wave velocity (Vs) profile of the subsurface. It analyzes surface waves (specifically Rayleigh waves) generated by active or passive sources to infer the stiffness and density variations of the soil and rock layers. This information is commonly used for geotechnical site investigations, earthquake hazard assessment, and near-surface geological mapping.
