One of the best near surface seismic energy sources

What is about

MASW is an important type of near-surface seismic method that has multiple applications in geophysics. This website is dedicated to providing resources regarding MASW seismic exploration, including information about different types of surveys (e.g., active source, passive microtremor source, 1-D, 2-D, and 3-D), organizations that provide services and equipment, and other considerations like theory, concepts, innovations, concerns, and credits. In addition, this site offers links to other websites devoted to learning more about MASW seismic methods.

More disclaimers in case the others were overlooked.

The information provided by is often based on opinion and clearly not a replacement for studying books and manuals, common sense, experience, or for acquiring the education necessary to conduct successful geophysical surveys. A background in physics, geology, geophysics, engineering, and/or mathematics benefits survey designers and operators. If one is looking for geophysical reference material, one can find a variety of material by searching the internet (e.g., manufacturers’ websites or government agencies). Because there is always the potential for misinformation here and throughout the internet, it is highly recommended that one goes through all procedures at the office or home base before leaving for a project. Surely, it is very important to experiment with geophysical equipment over known conditions and to understand how the equipment operates and responds. As noted throughout the site, visitors are not allowed access, unless they agree to the terms, conditions, and report errors and omissions for review.
