Abstract
The results of seismic monitoring of Magadan region, Chukotka Autonomous Area and adjacent sea shelf (Okhotsk, Chukchi, Bering and East Siberian seas) are given. The information about 12 digital seismic stations and monitoring equipment types and parameters is given. Maps of earthquake energy representativeness, seismic stations and epiсenters are presented. The distribution of earthquake number by energy classes and total seismic energy by six regions of North-East of Russia is given. The information about 234 events with energy classes КР=6.0–12.8 is included in the catalog. All hypocenters are located within the Earth's crust. Earthquake epicenters in Kolyma area are plotted on the tectonic zoning scheme. The strongest earthquake in 2014 with MPSP=4.5 (КР=12.8) occurred on July 4 in Kolyma area and was called Elgenskoe II. It was sensible with intensity I=4. Monitoring in 2014 showed decrease of seismic activity in Okhotsk sea area and its increase in the Kolyma. Spatially, all the earthquakes of the North-East of Russia are traditionally concentrated within the large seismogenic zones: the Chersky, the North Okhotsk and the Trans-Bering Sea.
