MASW. MASW is a seismic method that uses surface waves (specifically fundamental mode Rayleigh Waves) to estimate shear wave velocities. A hammer or other impact source is used to generate a surface wave. The propagation velocities of that wave are recorded using an array of low frequency geophones (4.5 Hertz). Apr 10, 2020 · MASW is a seismic method that can be used for geotechnical characterization of near-surface materials [3,4,5,6]. In this paper, the details of field investigations carried out with MASW to find soil profiles are presented.
