The distribution of earthquake hypocenters in the territory of Armenia is obtained based on data from seismological bulletins for 1970–2012. It is shown that in addition to crustal earthquakes, there are deep earthquakes with a hypocenter depth down to 300 km. The seismicity is concentrated primarily in the northwest of the republic in the region adjacent to the Javakheti Upland. The positions of the main shock and the aftershocks of the December 1988 Spitak earthquake are determined separately. It is shown that the aftershocks of this earthquake cover a big area, extending to a depth of 100 km, although most of them are located at a depth of ~27 km.

Previous results on the location of crustal earthquake foci in the Caucasus clearly show that the methods used in seismic service practice to determine the hypocenters of earthquakes do not...

Some aspects of the seismicity the Caucasus are considered based on the earthquake catalog from 1962 to 2011, which includes data on about 40000 seismic events with magnitudes from −1.0 to 7.5. Correl

To solve multiple geological and geophysical problems, in particular, the forecast of strong earthquakes, seismic zoning, and earthquake-resistant engineering, it is necessary to have...

The question of the existence of deep earthquake sources in the Caucasus is extremely important both for solving geodynamics problems, assessing seismic hazard, and seismic zoning of the...

The modern seismological network of the Caucasus contains a little more than 300 seismic stations. Despite the fact that the number of stations is rather large, they are not uniformly...
