Abstract

The previously obtained results on determining the location of the centers of crustal earthquakes in the Caucasus clearly indicate that the methods used to determine the earthquake hypocenters used in the seismic service do not allow accurately locating seismic events. In addition, the use of only one velocity column or one set of hodographs for determining earthquake hypocenters for all stations in the network also does not contribute to the exact determination of the position of earthquake hypocenters. In order to determine the position of the centers of earthquakes with high accuracy (Figure 1), it is necessary to have a fairly detailed idea of the deep structure of the earth’s crust and upper mantle in the studied region. At the same time, it is advisable to take information about the region’s structure not from earthquake data, but from other observations, for example, from deep seismic sounding (DSS). Based on seismological bulletins of the Caucasus for 1970-2015. The coordinates of the hypocenters of the earthquakes of the Caucasus were redefined. The general picture of the distribution of earthquake hypocenters in the Earth’s crust of the Caucasus differs significantly from the distribution of hypocenters in the catalog.
