VAHDATS EARTHQUAKE at 10 November 2013 with КР=12.4, MS=4.7, I0=6 (Tajikistan)

Abstract

On November 10, 2013, the strong earthquake occurred in the north part of Kafirnigan-Vakhsh of the anti-clinor raising, in the zone of the Iliak-Vakhsh fault. The pleistoseist zone of this earthquake with intensity I=6 and area about 30 km2 is located within Sangpar anticlinal raising. Information about the consequences of the earthquake was collected in 76 settlements of Tadjikistan, including Ii=4 in its capital, Dushanbe. Three settlements located on a slope and at the bottom of Sangpar mountain have suffered most strongly. Almost 70 % of dwelling-houses came in uselessness there. The map of isoseists extended to the northeast was made with the isolines of I=6, 5, and 4. The area of the isoseist with I=5 is 400 km2 and 3500 km2 for the iso-seist with I=4. The type of movement in the source is a reverse fault with a slight strike-slip along both possible rupture planes. It was preceded by 15 foreshocks and had about 400 aftershocks. It should be noted that this area is quite active in seismic terms, but there were no earthquakes with an intensity of more than 7
