The Present-Day Seismicity of the White Sea Region

摘要

A revised earthquake catalog has been compiled for the White Sea region for the period between 2005 and 2016. The earthquake parameters were revised using a single velocity model (BARENTS), a single methodological approach (Generalized Beamforming), and all available raw data and bulletins of Russian and foreign seismic stations. The location of two nuclear explosions detonated on July 18, 1985 and September 6, 1988 in northern European Russia for civilian purposes showed that the algorithm for calculating hypocenter parameters combined with the BARENTS velocity model is an effective tool. The resulting earthquake catalog enabled us to reveal the leading patterns in the distribution of recent seismicity in the White Sea region.
