Abstract

The parameters of the seismic regime of the eastern zone of the Central Caucasus are deter-mined based on the new catalog data. A similar study is being carried out for the third time: in 1996, 2015 and 2021. The basis for work in the area surrounding Grozny was laid in 1996 by a comprehensive study of geological, geomorphological, geophysical and seismological ma-terials. When comparing the results, the stability of the seismic regime parameters was estab-lished: the repetition schedule b and seismic activity A3.3 near Grozny, the capital of the Che-chen Republic and a large industrial center in 2015 and 2021. In both cases, the estimates were performed on the same the same territory bounded by coordinates: 41.1-45.6N and 42.6-48.8E. The same basic earthquake catalog was used for the calculations. The difference was in the number of events that took place in this territory from 2015 to 2020 inclusive.
