ParkSeismic LLC provides services in seismic investigation of geotechnical engineering projects including seismic site
characterization (SSC) for Vs30m evaluation, wind-turbine site characterization, bedrock topography mapping, sink-hole
hazard evaluation, detection of buried subsurface features of various types, soil characterization, etc., by using a special
seismic technique called the MASW method. The multichannel analysis of surface waves (MASW) method is a relatively
new ground-scanning method utilizing one type of elastic waves (surface wave) long studied and utilized in the earthquake
seismology. The main advantage of this method is highly reliable survey results usually presented in 2-D or 3-D formats
even under significantly unfavorable conditions such as ambient noise.
Seismic Site Characterization for Vs30m
What is MASW?
What is Seismic Survey?
In most cases, field survey can be accomplished within one or two days for a moderate size survey site (e.g., 100m x
100m) and draft results can be obtained by the next day, helping the geotechnical field process move quickly.
