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)

Famous quotes containing the word exploration:
“For women who do not love us, as for the “disappeared”, knowing that we no longer have any hope does not prevent us form continuing to wait. We live on our guard, on watch; women whose son has gone asea on a dangerous exploration imagine at any minute, although it has long been certain that he has perished, that he will enter, miraculously saved, and healthy.”
—Marcel Proust (1871–1922)
