Abstract
New data of instrumental and macroseismic studies of the significant Nevelsk earthquakes are presented. The MSK-64 intensity of the major events was VII–VIII (VI–VII), magnitude M LH = 6.3 (6.0). The seismic events occurred on August 2, 2007 near the southwestern coast of Sakhalin Island. We have collected and analyzed the available local, regional, and global seismic records, which has allowed us to perform a detailed study of the seismicity in the source zone and the mechanisms of both the mainshocks and aftershocks. Analysis of the 3D spatial distribution of the sources of the mainshocks and their multiple aftershocks, of the features of the source mechanisms, and of the data on coseismic deformation in the coastal part of Sakhalin Island has allowed us to clearly outline the source zone and construct reliable dislocation models for the mainshocks.
