Abstract
The history of instrumental observations in the northwestern East European Platform and the degree of seismological knowledge of the White Sea region is presented. The paper describes the modern seismicity of the White Sea region and considers in detail the strongest earthquake in the region for the last decades, which occurred on November 5, 2019, and, according to some features, can be thought to be unique to the region. The earthquake epicenter is located in the area of the interbasin bar dividing the Kandalaksha and Kolvitsky grabens. The calculated focal mechanism of the source shows the normal dip slip of blocks along the fault, which corresponds to he modern extension of the crust and the continuing development of the Kolvitsky graben.
期刊介绍：
Seismic Instruments is a journal devoted to the description of geophysical instruments used in seismic research. In addition to covering the actual instruments for registering seismic waves, substantial room is devoted to solving instrumental-methodological problems of geophysical monitoring, applying various methods that are used to search for earthquake precursors, to studying earthquake nucleation processes and to monitoring natural and technogenous processes. The description of the construction, working elements, and technical characteristics of the instruments, as well as some results of implementation of the instruments and interpretation of the results are given. Attention is paid to seismic monitoring data and earthquake catalog quality Analysis.
