European Fault-Source Model 2020 (EFSM20)

The European Fault-Source Model 2020 (EFSM20) was initially designed as a product of the EU H2020 Project SERA (WP25-JRA3) to fulfill the requirements related to active faulting of the 2020 update of the European Seismic Hazard Model (ESHM20) following the probabilistic framework established for the 2013 European Seismic Hazard Model (ESHM13). EFSM20 is now part of the portfolio of the EFEHR services.

EFSM20 has two main categories of seismogenic sources: crustal faults and subduction systems. Crustal faults provide the hazard model with seismicity rates in various tectonic contexts, including onshore and offshore active plate margins and interiors. Subduction systems provide the hazard model with slab interface and intraslab seismicity rates. The model includes 1,248 crustal faults spanning a total length of ~95,100 km and four subduction systems (Gibraltar, Calabrian, Hellenic, and Cyprus Arcs), with a focus on an area encompassing a buffer of 300 km around all target European countries (except for Overseas Countries and Territories, OTCs) and on a maximum of 300 km depth for slabs. Besides the original dataset, EFSM20 features 3D fault-source geometries made of triangular meshes that can be used in various applications of earthquake modeling.

The main EFSM20 dataset includes all fault-source parameters.

The 3D fault-source geometries made of triangular meshes are a derived product of EFSM20.

Disclaimer

The European Fault-Source Model 2020 (EFSM20) was designed to serve as input to the European Seismic Hazard Model 2020. For these reasons and its intrinsic nature, EFSM20 cannot be guaranteed to be complete, accurate, and updated in any part necessary for its use in different contexts or applications. Although we made every possible effort to supply the best available information, no warranty, expressed or implied, is provided regarding the accuracy and reliability of the data supplied in EFSM20. Users are invited to consider the inherent epistemic uncertainty of such a database in earthquake-related hazard analyses (PSHA, PTHA, PFDHA). We recall that EFSM20 was designed for analyses at the scale of a continent (the Euro-Mediterranean region) and that it is thus necessary to add local and site-specific investigations when using EFSM20 data for studies at more local scales. Users are also cautioned to carefully consider the nature of EFSM20 content before using it for decisions concerning personal or public safety or concerning business involving substantial financial or operational consequences.
