Abstract:
1. A method for predicting seismic events, the method comprising: supplying direct current electrical energy in a plurality of ground or rock electrical resistivity or electrical conductivity detection stations, said detection stations being arranged in areas distributed over a defined territory, each detection station being connected to a detection unit having current electrodes and potential probes arranged in the ground, whereby at least one probe is introduced into a survey hole to detect the resistivity or electrical conductivity of the ground or rocks; detecting electrical current and induced potentials in the ground via said electrodes and said potential probes for the calculation of resistivity or electrical conductivity in the ground; acquiring and storing the detected resistivity or electrical conductivity data; transferring said resistivity or electrical conductivity data to means for analysis and processing; and evaluating resistive drops in relation to preset values, corresponding to the approach of a seismic event.
