Abstract

Various and expensive sources for deep seismic explorations have been proposed (Domenico, 1958; Dobrin, 1960; Ari Ben-Menahem et al., 1981), buth there are no both suitable and inexpensive devices available for high-resolution shallow prospecting on land. Shallow prospecting, with a depth-range from some meters to some hundred meters, has not been taken into much consideration in the traditional seismic exploration, except in some engineering and geologic investigations. The main reasons for this lack of interest may be the missing economic considerations and the unfavourable wave propagation conditions at higher frequencies, due to the inhomogeneities of the weathered top layer of the earth. Nevertheless, shallow exploration techniques could offer a very useful tool for a more systematic survey of the near-surface structure.
