European Fault-Source Model 2020 (EFSM20): online data on fault geometry and activity parameters
The European Fault-Source Model 2020 (EFSM20) provides harmonized data on fault geometry and activity parameters for faults capable of generating earthquakes of magnitude 5.5 or greater across the Euro-Mediterranean area. Originally compiled under the EU SERA Project (Work Package 25, JRA3), it serves as a standardized input for ground-shaking hazard assessment, notably the European Seismic Hazard Model 2020 (ESHM20). The database is hosted, maintained, and distributed by INGV (Istituto Nazionale di Geofisica e Vulcanologia) through the EDSF installation, operated under EPOS-ERIC, TCS EPOS-Seismology, the EFEHR Consortium, and the EPOS-MIUR Joint Research Unit.The European Fault-Source Model 2020 (EFSM20) was initially compiled in the framework of the EU Project SERA, Work Package 25, JRA3. EFSM20 includes only faults deemed capable of generating earthquakes of magnitude equal to or larger than 5.5 and aims at ensuring a harmonized input for use in ground-shaking hazard assessment in the Euro-Mediterranean area, namely the European Seismic Hazard Model 2020 (ESHM20). The EFSM20 database is hosted, maintained, and distributed by INGV through the EDSF installation (https://seismofaults.eu/) operated under the auspices of the EPOS-ERIC, TCS EPOS-Seismology, EFEHR Consortium, and the EPOS-MIUR Joint Research Unit.
