Abstract: The main object of the database is the individual seismogenic source, intended as a simplified and georeferenced 3D representation of a fault plane. Individual seismogenic sources (GG sources) are identified through geological and geophysical investigations, are capable of primary slip during a large earthquake and are assumed to exhibit “characteristic” behavior with respect to rupture length/width and expected magnitude. Seismogenic sources that cannot be reliably assessed using geological and seismological data are derived from quantitative treatment of historical earthquake data (MW, MP, and MD sources). In addition to the individual sources, the new Database stores seismogenic areas (SA), crustal bodies capable of M ≥ 5.5 earthquakes for which a geographic outline, predominant faulting mechanism, effective depth, and expected maximum magnitude are supplied. Seismogenic areas are drawn with consideration of large set of available evidence, including known large-scale tectonic structures, major earthquakes not associated with obvious tectonic structures, seismicity patterns, and long- and short-term strain observations.
