SEISMICITY of the EAST BALTIC REGION in 2016–2017

Abstract

Information on seismic monitoring in the East Baltic region for 2016–2017 is presented. During this period of time, several tectonic earthquakes occurred, the epicenters of which are located in the north and northwest of Estonia and in the area of Lake Võrtsjärv. The territory of Estonia and the adjacent waters of the Baltic Sea are still the most seismically active parts of the East Baltic region. Attention is drawn to the inherited nature of seismicity, i.e. in the areas of modern earthquakes, earthquakes had already occurred before the instrumental period. Another feature of several earthquakes in the East Baltic region is their association with meteorite craters, which are most often found in the East Baltic region in Estonia and near it, in the Baltic Sea. As before, the bulk of seismic information is associated with man-made explosions in industrial quarries and in the Baltic Sea. The identification of earthquakes of small magnitude remains an urgent problem.
