Canada’s National Earthquake Database combines raw seismograph data, measurements, and derived parameters from national seismic networks.
Database of Individual Seismogenic Sources
DISS maps tectonic, fault, and paleoseismological information for assessing seismic hazard, including potential earthquake sources in Italy and nearby areas.

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.
