SARIKHOSOR EARTHQUAKES on March 29, 2018 with KR=13.1, Мs=5.1, I0=6 and March 7, 2019 with KR=12.1, МS=4.1, I0=5–6 (Tajikistan)

Abstract

General information about the tangible earthquakes that occurred on the territory of Tajikistan in 2018–2019 and their confinement to tectonic structures is given. The most active tectonic structures during this period within which strong seismic events occurred are determined. The results of a survey of macroseismic manifestations of March 29, 2018 and March 7, 2019 earthquakes, which occurred in the eastern part of the Tajik depression, and their isoseist maps are presented. An assumption about the possible influence of two large reservoirs on the increase of the seismicity of the region is made. An analysis of the depths of earthquake sources in comparison with the geological and tectonic structures of the region is made. The difference in the depths of earthquakes, determined by different seismological services, makes it difficult to link the source of seismic events to tectonic structures and to determine their parameters.
