AZERBAIJAN

Abstract

In 2013, four digital stations («Horadiz», «Agdam», «Beylagan», «Yardimli») were opened. The complete network consisted of 35 digital stations. The network of analog stations continued to operate unchanged. In 2013, the set of parameters for estimating the earthquake size decreased – determining the magnitudes MPVA and the energy classes КР was stopped. Only the local magnitude ML Азр is measured and then recalculated into energy class КР. The seismicity of the territory of Azerbaijan is analyzed. Maps of epicenters of earth-quakes are given. The total number of earthquakes in 2013 was 5248 with ML Азр>0.1, of which only 165 with ML Азр3.0 are published in the Yearbook. A decrease in the seismic activity of the studied territory was noted. Powerful seismic activity, observed in 2012, was replaced in 2013 by a decrease in seismicity to the background level. The most significant seismic event on the territory of the Republic was the April 18 earth-quake with ML Азр=5.3 with macroseismic effect I0=4.
