Tectonic position, geological manifestations of sources, and aftershock processes for a series of strong earthquakes of 2016–2017 in central Italy

Abstract

Based on seismological, geodynamic, and seismotectonic data on a series of strong earthquakes which occurred in 2016–2017 in central Italy, the tectonic positions and geological manifestations of these events are determined. The aftershock processes of these earthquakes are studied. It is found that epicentral clouds of mainshocks and aftershocks almost overlapped each other, so these earthquake sources in aggregate can be classified as a high-magnitude earthquake swarm.
