Database of Individual Seismogenic Sources (DISS), version 3.3.0: A compilation of potential sources for earthquakes larger than M 5.5 in Italy and surrounding areas.

DISS is a georeferenced repository of tectonic, fault, and paleoseismological information. The core objects of DISS are: - the individual seismogenic source, a simplified and three-dimensional representation of a fault plane. Individual seismogenic sources are assumed to exhibit \"characteristic\" behavior with respect to rupture length/width and expected magnitude; - the composite seismogenic source, an elongated region containing an unspecified number of aligned seismogenic sources that cannot be singled out. Composite seismogenic sources are not associated with a specific set of earthquakes or earthquake distribution; - the debated seismogenic source is an active fault that has been proposed in the literature as a potential seismogenic source but was not considered reliable enough, or for which there is not yet sufficient information, to be included in another category. - the subduction zone, which is a complex three-dimensional representation of the detachment at the base of the accretionary wedge, the interface between the two plates at crustal depth, and the dipping slab at mantle depth. Individual and Composite seismogenic sources are two alternative seismic source models to choose from. They are tested against independent geophysical data to ensure the users about their level of reliability. A number of scientists have already used DISS in successful applications concerned with various aspects of earthquake hazards. Each record in the Database is backed by a Commentary, a selection of Pictures, and a list of References, as well as fault scarp or fold axis data when available (usually structural features with documented Late Pleistocene - Holocene activity). The Database can be navigated through a web browser, downloaded in various GIS file formats, or accessed through OGC web services. This Database contains data, software, texts and elaborations prepared by researchers of the Istituto Nazionale di Geofisica e Vulcanologia.
