Table 1: List of earthquakes located by INGV between 2000 and September 2024 within 35 km from Octuni (40.732 N-17.578 E), with M \(\geq\) 2.0 ID = identification number. Date is expressed in Year-Month- Day. Time is the earthquake origin time (UTC), Depth (km) is the earthquake depth (fixed if marked with *). RMS (s) is the root mean square of the travel time residuals; M is the “preferred” magnitude taken from INGV Seismic Bulletin (M\({}_{\rm L}\), Md or Mw). Of these 32 events, seismograms were available for a review of picking only for the RSN recordings from 2008 onward, while for those up to 2007, we used the time picks provided by INGV.
