Seismogenic fault and area sources for probabilistic seismic hazard model in Slovenia

DOI

The Slovenian Environment Agency (ARSO) and Geological Survey of Slovenia (GeoZS) jointly developed a new seismic hazard model for the 2021 Slovenian probabilistic seismic hazard assessment (PSHA) in the scope of a seven-year project starting in 2014. Fault and area source parameters and their uncertainties were estimated, using all available seismological, geological, and seismotectonic data, models, and interpretations. A fault source is a 3D structure, which is described by a fault trace, dip, seismogenic depth, and parameters that describe its kinematics (activity, fault source type, rake, slip rate values) and maximum magnitude the source can generate. An area source is represented by a polygon described with characteristic structural domain (faults, fault systems) and its style of faulting, seismogenic/hypocentral depth, activity rate, and maximum magnitude. The database contains 89 seismogenic faults and 18 area sources in Slovenia and its surroundings. Data includes shapefiles describing the geometry of seismogenic sources, and Excel parametrization tables, linked through source ID and name. Shapefiles provide fault surface traces and polygons for area sources. Both fault and area parametrization tables include two Excel sheets: the first level (sheet names Fault sources and Area Sources) describes all estimated source parameters, and the second (sheet names FS_PSHA and AS_PSHA) consists of parameters that were used in the 2021 Slovenian PSHA model and calculation of national seismic hazard maps.The owner of the database is ARSO, which led the PSHA and financed the seven-year project on active faults in Slovenia, carried out by GeoZS and ARSO. Seismogenic source delineation and estimation of many source parameters were done in the scope of this project. Other parameters were estimated by ARSO based on seismological data.

Data and metadata are provided in the following Excel sheets:Fault_source_parameters.xlsx; Fault sources; Help FSFault_source_parameters.xlsx; FS_PSHA Help; FS_PSHAArea_source_parameters.xlsx; Area sources; Help ASArea_source_parameters.xlsx; AS_PSHA Help; AS_PSHA
