Park Seismic LLC specializes in the services of the MASW method that provides subsurface shear-wave velocity (Vs) profiles (1-
D, 2-D, and 3-D) for geotechnical engineering depths (e.g., about 30-m depth).

MASW Software ParkSEIS© (v. 3.0) AUTO - Release Announcement

    A new version of ParkSEIS (v. 3.0) AUTO is now available.  The most significant
    feature is the "AUTO" module which provides a fully automated default sequence
    of MASW data analysis.  This means you can now generate shear-wave velocity
    (Vs) profiles (1D or 2D) with one click after importing seismic data.  Please watch
this on YouTube.  The traditional manual approach is still available with even more advanced options for research and
QA/QC purposes.

ParkSEIS© is the most comprehensive and updated tool for MASW data analysis designed to generate shear-wave velocity (Vs)
information in 1-D profile, 2-D cross section, and depth slices.  It can also perform Back Scattering Analysis (BSA) of surface
waves to detect near-surface anomalies such as voids, tunnels, boulders, weak zones, etc.  MASW modeling is also included.  
ParkSEIS© (PS) can process seismic data sets from active, passive, and (active/passive) combined MASW surveys.  Visit the
website for more information.  

MASW Services for Geotechnical Projects - "You Collect, We Process and Report"

Park Seismic provides services in data processing and reporting in MASW surveys for various types of projects (wind-turbine, soil
and bedrock, void, weak zones, buried boundaries, etc.).  For cost-effective and time-efficient purposes, field surveys are usually
performed by a local geophysical company with experience in multichannel seismic surveys (refraction or reflection) according to
the field procedure, details of which we will provide.  We will then process acquired data and send you back the final report in a
compact form (click for sample
1-D and 2-D report) or a full format (click for sample 1-D or 2-D report).  The overall procedure
consists of following steps:

  1. Feasibility Inquiry - Free consultation on the scope of the approach
  2. Survey Plans and Cost Evaluation - Providing field logistics for data collection and estimated cost for the service
  3. Field Survey - Data collection by the local company
  4. Data Processing and Reporting - Processing data and preparation of report and output data (final deliverables)

For most common size of the project that takes a few days of field work, the final deliverables are usually available within a week
after receipt of the collected data.  
Contact us for free consultation.

MASW Services - Areas of Application

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 1-D, 2-D or 3-D formats even under
significantly unfavorable conditions such as ambient noise.

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.
