“…The redefinition of hypocenter parameters based on summary bulletin was carried out by using the Generalized beamforming method (Ringdal and Kvaerna 1989) in an improved form implemented in the NAS program (Asming et al 2017;. The algorithm for calculating hypocenters is described in details according to (Morozov et al 2019).…”

“…Previous studies have shown (Morozov et al 2019) that using the advanced algorithm implemented in the NAS program in conjunction with the rapid BAR-ENTS model provides relatively accurate hypocenter parameters and allows the use of this technique to recalculate all subsequent earthquakes in the White Sea region. The resulting redefinition of hypocentres does not differ fundamentally from the catalog of the Institute of Seismology in Helsinki, despite the extensive use of other additional data.…”

“…It allows to determine the parameters of earthquake hypocenters based on seismic stations located in wide azimuth and epicentre ranges, and to obtain high precision of earthquake hypocenter location. In addition, some studies have already been successfully carried out on parts of the White Sea (Morozov et al 2019) and are now supplemented by data from the western part of the White Sea -the territory of the Karelia Republic, which is also characterized by seismicity (Sharov et al 2007). The boundaries of the study area are shown in Fig.…”

This article is the result of previous studies to clarify the seismicity of the White sea, supplemented by similar studies on the continental part of the Republic of Karelia. The relocated catalog of earthquakes was created for the period from 2005 to 2016 for White Sea and the Karelian region. With the help of proven methods, the parameters of the epicenters of identified earthquakes were relocated and a map of current seismicity was obtained. The parameters of the epicenters were specified using BARENTS travel-time model, a single methodological approach (using Generalized beamforming) and all currently available source data and bulletins of Russian and foreign seismic stations. The obtained seismic catalog allowed us to identify the main patterns of the distribution of current seismicity in the White Sea region. Seismicity of the White sea and the Karelian region is characterized as low-magnitude (generally of low magnitude with ML<2.0). Most earthquakes in the White Sea are characterized by a focal depths up to 20 km. Analysis of catalog shows that the majority of earthquakes are concentrated in the north-western part of the defined area, in the continental part of Karelia and Kandalaksha graben. Some earthquakes were recorded in the eastern and central part of the White sea.
