The main purpose of this site is to provide those practitioners, researchers, and engineers who tap on the feasibility of the method for their own
projects with general information about the MASW method.  The site’s main categories include both practical and theoretical aspects.  The
practical categories are largely divided into
HARDWARE and SOFTWARE that are needed to perform MASW surveys.  They also include 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.

This site is operated by Park Seismic LLC specializing in the service of the MASW method.
Welcome To the Home of the MASW Seismic Technique

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.  Since its first introduction in the late 1990s, it has been
utilized by many practitioners and researched by many investigators worldwide.
