Triangular meshes are useful for several applications of earthquake modelling that require a discretization of the fault plane, e.g., heterogeneous slip distributions. EFSM20-Meshes was created to fulfil the objectives of the Geo-INQUIRE project and 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. EFSM20-Meshes is derived from the European Fault-Source Model 2020 (EFSM20), and its compilation aims to replicate the geometry of its fault sources with triangular meshes as closely as possible. The adopted procedure includes the following steps. 1) extract triplets of spatial coordinates (latitude, longitude, depth) of evenly spaced points resting on the EFSM20 fault planes; 2) obtain triangles through Delauney triangulation; 3) remove spurious triangles. The results of this procedure can be replicated through a dedicated PyQGIS tool.
