SurfSeis© software was developed at the Kansas Geological Survey to process seismic data using the multichannel analysis of surface waves (MASW) method. Obtain shear-wave velocity (Vs) with depth (z) estimates using SurfSeis. Surface waves have historically been the bane of near-surface reflection seismologists.The measurement of the shear wave velocities (Vs) of soils is an important aspect of geotechnical and earthquake engineering, due to its direct relation to the shear modulus (G), which in turn influences the stress–strain behavior of geomaterials. Vs can be directly measured or estimated using a variety of onsite tests or in a laboratory. Methods …The MASW testing typically uses only one single shot, limiting the obtainable wavelengths due to the single source at a single nearest offset. Combining the merits of these two methods, a multi-shot common receiver configuration survey is proposed to acquire multi-station wavefield for 2D wavefield transformation using as few as two receivers ...
