Detailed study of the 2010-2014 Pollino (Italy) seismic sequence with absorption and scattering imaging of the surrounding area

Abstract

A detailed study of the seismic sequence occurred in the western sector of the Pollino Range (Southern Italy) between 2010 and 2014, and an imaging of the surrounding area, have been performed in this thesis. The sequence, occurred in this area considered as a seismic gap in the transition zone between the Calabrian Arc and the Southern Apennines, developed as a seismic swarm, rather than an aftershock sequence. The large number of small-to-medium earthquakes (mL < 5.0) recorded by the seismic stations operated by different institutions in the area allowed to: 1) perform high quality imaging and characterization of the seismogenic volume responsible for the Pollino swarm using relative location technique; 2) characterize the properties of the medium involved during the swarm and nearby, separating scattering and absorption contribution to the total attenuation of coda waves; 3) assess site effects for seismic risk mitigation purpose by applying HVSR technique and polarization analysis...
