Description |
In this article we have compared the results of seismotectonic and paleoseismogeologic investigations for representative segments of the two fold systems of the AlpineHimalayan mobile belt (in the North
west Caucasus and West Himalayas). It has been found that during the previously identified “seismic gaps,”
in both cases, we are dealing with primary dislocations (seismic ruptures) of ancient historical and prehistoric
strong earthquakes. According to estimations, the magnitude of one act seismogenic displacements in the
first region was about 6.5–7.0, and the recurrence period ranges from 500 to 1500 years on average. In the
West Himalayas, the overthrust displacements along the ruptures were 6–7 m, which corresponds to an 8.0
magnitude earthquake. At the same time, the recurrence period of strong earthquakes during a seismic gap in
the Himalayas was 500–1000 years, which is similar to that in the Caucasus. The data collected also demon
strate the correct preliminary estimation of the seismic potential of zones of seismic quiescence in both the
studied fold systems.
