Subject Classification: | 04. Solid Earth::04.02. Exploration geophysics::04.02.07. Instruments and techniques | Abstract: | We present the data on particular electric signals in the frequency band around 8 kHz emitted by various types of rocks that are subject to pressure and fracture in the laboratory and recorded in the surrounding air. A similar type of electric signal was recorded as an electric precursor of the earthquake with magnitude 5.0 that occurred on September 14, 2003 at 22h 42m 50s in the Tosco-Emiliano Apennines (lat. 44.22 N, long. 11.35 E). The precursor was recorded with an instrument called radio-geophone installed in an experimental station located near Cascia (PG) (lat. 42.8 N; long. 13.1E; 900 m a.s.l.). |
