The Yakut and Magadan regional seismic networks have recorded more than 6000 earthquakes in northeast Russia over the past 50 years. Seismicity of the region is represented by a broad (up to 400 km) epicentral band extending from the Lena river delta along the Chersky Range system through Northern Priokhotye and Shelikhov Bay in the Sea of Okhotsk to Kamchatka peninsula. The band makes part of the large Arctic-Asian seismic belt [1] intersecting the Arctic ocean and the Asian continent and linking the seismicity of the Arctic with that of the Pacific region. The seismic zone of the Chersky Range is traceable for a distance of more than 8000 kilometers separating the Eurasian and Okhotsk plates from the North American one. Most seismically active is the southeastern flank of the Chersky Range zone. Here, on the territory between the Indigirka and Kolyma river valleys and the northern shore of the Sea of Okhotsk, including its shelf, a large epicentral cluster has been recorded. Over a dozen
