This catalog contains the focal solutions calculated for earthquakes with a magnitude at least 2.7, located since 1999 in Sicily and southern Calabria by the Istituto Nazionale di Geofisica e Vulcanologia - Osservatorio Etneo, Sezione di Catania. The database is periodically updated; you can read a more complete description of our project in Scarfì, L., A. Messina, C. Cassisi. Sicily and Southern Calabria focal mechanism database: a valuable tool for the local and regional stress field determination, Ann. Geophys., 56, 1, 2013, D0109; doi:10.4401/ag-6109.
