TALDYK EARTHQUAKE on November 17, 2015 with KR=14.1, Mw=5.5 (Kyrgyzstan)

Abstract

Information on the earthquake with KR=14.1, which occurred in Kyrgyzstan on November 17, 2015, is presented. Its epicenter is related to the South Fergana zone of the Osh region, in which felt earthquakes with intensity up to I=8–9 occurred repeatedly. This event was named Taldyk according to the settlement nearest to the epicenter. The earthquake was accompanied by numerous aftershocks: for the first day, 189 events were registered, for the second – 196, for the third – 84. Most part of the aftershocks is localized within the depth interval of 12–13 km, which is practically equal to the depth of the main shock (h=13 km). The focal mechanism of the main shock has a reverse type with strike-slip components. No serious investigation of the consequences of this earthquake carried out. Some macroseismic data are received from field reports of the station operators. For a more complete analysis of the possible impact of this earthquake and, first of all, for the needs of the Ministry of Emergency Situations of Kyrgyzstan Republic, a map of theoretical isoseismals was created.
