| Zusammenfassung |
| The VLF/LF radio signals method for studying preseimic activity is applied to
the Abruzzo earthquake (M=6.3, 6 April 2009). The data collected by three
receivers located in Moscow (Russia), Graz (Austria) and Bari (Italy) at
about 3000 km, 1000 km and 500 km from the epicenter were used. The
signals received from the Sardinia (20.27 kHz) and the Sicily (45.9 kHz)
transmitters, both located in Italy, were compared with those received from
the Iceland (37.5 kHz), the Great Britain (19.58 kHz) and the Germany
(23.4 kHz) transmitters. The propagation paths of the two Italian
transmitters cross the epicentral area (seismic paths) unlike the paths of
the other three signals (control paths). Using two different analyses, that
are the study of the night-time signal and the research of shifts in the
evening terminator times, clear anomalies were revealed 2–8 days before the
occurrence of the Abruzzo earthquake in the seismic paths, while no anomalies
have been found in the control paths. |
