MASW is an acronym of Multichannel Analysis of Surface Waves.  It is a seismic exploration technique first introduced in GEOPHYSICS by
Park et al., (1999).  It evaluates ground stiffness by measuring shear-wave velocity (Vs) of subsurface in 1-D, 2-D, and 3-D for various types of
geotechnical engineering projects in the most common depth range of 0-30 meters.  

The main purpose of this site is to provide general information about the MASW method.  The site’s main categories include both practical and
theoretical aspects.  The practical categories include
HARDWARE and SOFTWARE needed to perform an MASW survey as well as the final
PRODUCT from the survey.  Theoretical categories deal with what it is, procedure, table of optimum acquisition parameters, history of surface-
wave method, types of MASW method, and applications.  Also included is a general description of the seismic method.  These contents are
explained in the simplest manner possible, and the articles listed in the  
References section will cover in-depth technical aspects.
