DAGESTAN

Abstract

For the Dagestan seismic network consisting of nine analog and seven digital seismic stations in 2013, the values of the maximum and reliable earthquake detection range are given depending on the energy class КР. On their basis, the contours of the energy representation of earthquakes with Кmin=5, 6, 7 are constructed, and earthquakes with КР³8 are recorded without loss in the entire area of responsibility of the Dagestan branch of GS RAS within the coordinates: j=41.0–44.0°N, l=45.0–49.0°Е. The coordinates of hypocenters were determined by the hodograph method using local hodographs. The classification of earthquakes, as before, was carried out in T.G. Rautian energy classes. 684 earthquakes with КР=4.2–12.7 and total energy of SЕ=2.13×1012 were recorded in total. The notable events were the Georgian-Dagestan and Kichi-Hamri earthquakes, the last of which was described in a separate article of this yearbook. On the basis of the map of the epicenters of all earthquakes, seismicity was described in detail in seven regions.
