Focal Mechanisms in southern Tyrrhenian Sea and northern Sicily between 1 January 2000 and 31 August 2021 (STyrr_FM_2000-2021)

We computed new 268 focal mechanisms (1.3≤M≤4.6), with rays traced through the 3D velocity model of Scarfì et al. 2018, of events occurred in the southern Tyrrhenian Sea and northern Sicily between 1 January 2000 and 31 August 2021. The earthquakes were recorded by the land seismic network managed by the INGV and a seafloor network, consisting of 14 Ocean Bottom Seismometers and Hydrophones, deployed during the Tyrrhenian Deep sea Experiment (TYDE, December 2000 – May 2001; Dahm et al., 2002; Sgroi et al., 2006) and the NEMO-SN1 seafloor observatory (October 2002 – February 2003; June 2012 - June 2013; Sgroi et al. 2021).
