Abstract

Seismic phenomena related to underground karstic voids were discovered by a high-energy source associated to an analogical-digital system. The seismic signals include diffraction, reflection, echo, and anomalies in the frequencies and amplitudes of signals. Suitable evaluation using the Fourier series allowed the checking and the quantifying of these anomalies. (LW).
