| Zusammenfassung |
| Javakheti Highland
is one of the most seismic active regions of the Caucasus. The majority of
earthquakes observed throughout the region occur within this small area (f
= 40.8° – 41.8° ; l = 43.3° –
44.3°). One can expect that exclusive seismic activity of Javakheti
Highland testifies to global geophysical processes which take place
throughout the Caucasus region. Based on the above-mentioned, of interest
was to study variation with time of the number of earthquakes occurring in
Javakheti region. We analysed some 695 relatively small earthquakes (2.5 <
M < 6.0) observed in Javalkheti Highland within the period of 1961–1992
with regard to large earthquakes M > 6.0 of the region which
occurred in the same period. It was found that each large earthquake of
the Caucasus is anticipated by clear precursor in a form of an anomalous
change in the number of relatively small earthquakes in Javakheti
Highland. |
