Database of Individual Seismogenic Sources

DISS is a georeferenced repository of tectonic, fault, and paleoseismological information expressly devoted, but not limited, to potential applications in the assessment of seismic hazard at the regional and national scales.

• it represents faults in 3D;
• all its records are fully parameterized;
• it tends to completeness.

The core objects of DISS are:

• The individual seismogenic source, a simplified and three-dimensional representation of a rectangular fault plane. Individual seismogenic sources are assumed to exhibit "characteristic" behavior with respect to rupture length/width and expected magnitude.
• The composite seismogenic source, a simplified and three-dimensional representation of a crustal fault containing an unspecified number of 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 its parameters could not be constrained in order for it to be included in any of the other categories.
• The subduction zone, a simplified and three-dimensional reconstruction of the complex subduction system. It is mainly represented by the depth contours of the subducted slab. Like composite seismogenic sources, subduction zones are not associated with a specific set of earthquakes or earthquake distribution.
