| Popis: |
Robust noise technology is presented for the analysis of seismic-acoustic signals, which allows the use of noise in the signal as a carrier of information at the start of anomalous seismic processes preceding earthquakes. A station has been built based on this technology, which receives seismic-acoustic noises from the deep strata of the earth by means of 3–6 km deep steel bores suspended in oil wells, performing monitoring of the beginning of the latent period of earthquake formation. Experiments carried out at stations at Qum Island in the Caspian Sea since 01.05.2010 and in the town of Shirvan in the south of Azerbaijan since 20.11.2011 have proven the reliability and adequacy of results when monitoring and identifying earthquakes within a radius of 300–500 km, 10–15 h before the earthquakes are detected by standard seismic stations. |
