The Strong Earthquake in Sakhalin Island in September 13, 2020

The seismotectonic position of the strong earthquake that occurred in the southern part of Sakhalin Island on September 13, 2020, is considered. The maximum shaking intensity was reported in the town of Uglegorsk. The ground shaking with Community Internet Intensity CII = 5.5 caused damage to the buildings with low seismic capacity. Significant ground shaking in the study area had already taken place in the case of the Mw 6.8 Uglegorsk earthquake in 2000. It has been suggested that the recent earthquake was triggered by the 2000 Uglegorsk earthquake (Mw 6.8). Currently, Sakhalin oblast is considered as a pilot region for the implementation of a novel federal program for the relocation of people from dilapidated housing. In this respect, the proposed method of assessment of the seismic potential of fault zones in the areas where construction is planned, taking into account the postseismic effects, is of very high importance.
