A resistivity survey with small multi-transmitter devices was tested in the Vajont valley, in north-eastern Italy, with the purpose of imaging the deep sliding surface of the catastrophic landslide occurred in 1963. The waveform of induced potentials was clearly recognisable up to a distance of more than 1 km in single transmitter mode, while using multiple transmittes the threshold distance is probably far beyond and it was not reached. A potential of 0.02 mV was identified as the detection threshold.
