Abstract

Information on the strong Ilin-Tass (Abyi) earthquake recorded on February 14, 2013, in Northeastern Yakutia with Мw.=6.7 is provided. It arose to the Chersky seismotectonic zone (SZCH), which is part of the Arctic-Asian seismic belt that separates the Eurasian and North American lithospheric plates in Northeast Asia. The intensity of the shock at the epicenter corresponded to 9. The instrumental and macroseismic data, the focal mechanism, and the seismotectonic situation in the epicenter region are analyzed. The interconnections of the earthquake with the large regional Ilin-Tass fault are established. It is concluded that the occurrence of the Ilin-Tass (Abyi) earthquake occurred as a result of thrust displacements along the mentioned fault during the collision of the Eurasian and North American plates under compression conditions.
