Single Geophone Profiling (SGRP) Used in the Detection of Lateral Vetocity Changes: Example of Cavity Detection

The interest of this new type of research consists in setting up a new method based on the common seismic refraction and reflection methods which are sometimes too expensive and too complex to use. These reasons have led us to develop a new method, the Single Geophone Refraction Profiling (SGRP), which makes possible the rapid and inexpensive interpretation of a chosen site.
