Welcome to the web site of the multichannel analysis of surface waves (MASW) method.

MASW is a seismic exploration method evaluating ground stiffness in
1-D, 2-D, and 3-D formats for various types of geotechnical
engineering projects.  Since its first introduction in the late 1990s, it has been utilized by many practitioners and researched by
many investigators worldwide.

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
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.
