Estimating Stability and Resolution of Waveform Inversion Focal Mechanisms

The main aim of this study is to describe several tools for testing the stability and resolution of waveform inversion focal mechanisms already successfully adopted for crustal earthquakes occurred in the Calabrian Arc region, southern Italy. During the last years, our research team made continuous processing and improvements on Calabrian Arc earthquake focal mechanisms in order to increase their reliability and to expand the temporal and magnitude range of focal mechanism databases. Well constrained focal mechanisms obtained in the last years provide a key element to study the regional tectonic processes in the Calabrian Arc region characterized by high heterogeneity in terms of seismotectonics and kinematics.
