The presented database includes active, probably active and potentially active faults with trace lengths >5 km, systematically compiled and cataloged from a vast and highly heterogeneous dataset. Additionally, overall high rates of erosion, denudation and slope mass movement processes with rates up to several orders of magnitude larger than fault slip rates obscure the surface definition of faults and traces of activity, making fault parametrization difficult. Active fault identification is complicated by complex regional structural setting due to overprinting of different tectonic phases. The relative paucity of major earthquakes and low to moderate fault slip rates necessitate the use of geologic input for a more representative assessment of seismic hazard. About a dozen M w > 5.5 earthquakes have occurred across the national territory in the last millennium, four of which in the instrumental era.
The area at the junction of the Alps, the Dinarides, and the Pannonian Basin is moderately seismically active. We present the compilation of a new database of active faults in Slovenia, aiming at introducing geological data for the first time as input for a new national seismic hazard model.
