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.
Since version 1.01 was released a year ago (September 2015), the functionality and user friendliness of ParkSEIS© (PS) have
been greatly improved mostly due to extensive in-house operations, but also from suggestions and reports from users. Most
bugs found were minor, but a few of them were critical. All bugs we found have been fixed. Updates, additions, and
modifications incorporated into the current version (v. 2.0) are explained here. For a brief introduction of the software features,
