MASW is a seismic method that measures the shear-wave velocity distribution, thereby can be used to measure the arrangement of overburden and bedrock. It analyzes the dispersion of surface waves (usually the fundamental-mode Rayleigh waves). Like in other seismic methods, an array of geophones is used to measure the seismic waves.Multichannel Analysis Surface Wave (MASW) merupakan metode karakterisasi seismik yang berdasarkan analisis dispersi geometrik dari gelombang permukaan, ...Seismic Site Characterization.

MASW. Multichannel Analysis of Surface Waves (MASW) is a geophysical method that uses surface wave (Rayleigh wave) propagation to profile the subsurface. An MASW survey profiles subsurface shear wave velocity (shear stiffness). Surveys can be designed to provide high resolution near surface results, or to profile up to 60 meters depth.MASW-AS3KK-0.2-5P-24 MASW-AS3KK UL Compatible Cable from MISUMI.
