Recent seismicity in northern European Russia

摘要

A revised comprehensive catalog has been made for earthquakes that occurred in northern European Russia for the period between 2005 and 2017. The earthquake parameters were determined to greater accuracy using the same velocity model (BARENTS), the same location method (based on generalized beamforming), combining data from catalogs, bulletins, and (in part) from waveform supplied by regional seismograph networks in Russia and the Scandinavian countries. The resulting unified catalog formed a basis to assess the recent seismicity in northern European Russia, which occurs as low magnitude earthquakes. The distribution of earthquake epicenters is not uniform. The Fennoscandian Shield shows the highest activity (by seismicity rate and epicenter density), the next to follow are the northeastern Russian plate and the northernUrals Fold-Thrust Region. All earthquakes typically occurred at crustal depths.
