Welcome to the SurfSeis home page

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. With the development of MASW at the KGS has come an explosion in research and use of the MASW method for application to engineering, groundwater, and environmental problems. Scientists from around the world have shown the utility of surface waves as signal rather than noise.

Currently shipping SurfSeis 4

We are currently shipping Version 4.0. See How to order SurfSeis for ordering instructions, or view the Version 4.0 Flyer (PDF file, 2 MB). You can see the Version 3 Flyer here (PDF file, 353 KB). In addition, there is a free update for SurfSeis 4 users.
