| Presentation Summary: |
Geophysical tools and techniques can provide a variety of measurements and information about the subsurface that can dramatically improve our understanding of the physical properties of the rock and soil beneath our feet. In this presentation, John Diehl, President of GEOVision Geophysical Services will review multiple geophysical techniques that all Engineering Geologists should know including:
- Surface Wave surveys for Vs30 site characterization
- Seismic refraction for rippability
- Seismic reflection for shallow fault mapping
- Borehole techniques to measure shear wave velocity
Case studies and examples from actual projects will be shown and
explained.
