About Database of Individual Seismogenic Sources

The Database of Individual Seismogenic Sources (DISS) is a georeferenced repository of tectonic, fault and paleoseismological information for assessing seismic hazard at regional and national scale. It compiles potential sources for earthquakes larger than M 5.5 in Italy and surrounding areas.

It provides a GIS-based tool for exploring onshore and offshore faulting, with four categories of seismogenic sources and fault models for ground-shaking, tsunami hazard and primary surface faulting identification. The database is freely accessible and periodically updated, with the current release identified as version 3.3.1.

Key features

  • GIS-based exploration of onshore and offshore earthquake faulting
