Geophysical Exploration
Geophysical methods are used in geotechnical investigations to evaluate a site's behavior in a seismic event. By measuring a soil's shear wave velocity, the dynamic response of that soil can be estimated. There are a number of methods used to determine a site's shear wave velocity:
- Crosshole method
- Downhole method (with a seismic CPT or a substitute device)
- Surface wave reflection or refraction
- Suspension logging (also known as P-S logging or Oyo logging)
- Spectral analysis of surface waves (SASW)
- Modal Analysis of Surface waves (MASW)
- Reflection microtremor (ReMi)

“The future author is one who discovers that language, the exploration and manipulation of the resources of language, will serve him in winning through to his way.”
