ABSTRACT:
A seismic exploration process consisting of the application to the surface of the soil of a plurality of vertical impacts at points separated by a vertical trench cut into the soil. The vibrations propagating in the soil as a result of said impacts are then recorded, with the longitudinal wave components being eliminated from consideration. This makes it possible to produce agitation having a strong transverse wave component.
