In April – May 2021, in the Khabarovsk Territory and Sakhalin Region in the Far East Federal District of the Russian Federation, the Federal Research Center "Geophysical Survey RAS" deployed temporary networks as a part of Large-Scale Research Facilities – continuous seismic monitoring of the Russian Federation, adjacent areas and the world. The deployment of new stations provided a reliable integration of real-time seismic data into a centralized monitoring system for the Sakhalin Region.The seismic study has been performed in the Uglegorsk District, Sakhalin Region, where the Solntsevsky brown coal deposit – the most potential on the island – is located. There were presented the data on seismic events of different origin recorded since the stations had been brought into service. Emphasis has been placed on considerable improvements in epicenter location accuracy and enhancing possibilities of determining earthquakes and industrial explosions. There are shown the results of monitoring for earthquake mechanism studies. The monitoring system that is currently available allows recording the representative earthquake events with ML≥0.5 in the immediate vicinity of coal mines, thus providing the possibility of improving control of blasting work and of weak and potential induced seismicity caused by multiple anthropogenic impacts on subsoil. В апреле – мае 2021 г. на Дальнем Востоке РФ Федеральным исследовательским центром «Единая геофизическая служба РАН» были развернуты временные сети в Хабаровском крае и Сахалинской области как часть уникальной научной установки – комплекса непрерывного сейсмического мониторинга Российской Федерации, сопредельных территорий и мира. Установка новых станций надежно обеспечила интеграцию данных, поступающих с пунктов в режиме реального времени, в единую систему сейсмического мониторинга в Сахалинской области.Проведено исследование сейсмичности в Углегорском районе Сахалинской области, на территории которого расположено Солнцевское буроугольное месторождение, являющееся самым ...
