Database of Individual Seismogenic Sources

A compilation of potential sources for earthquakes larger than M 5.5 in Italy and surrounding areas


This version of the Database was the first to be expressly designed for widespread distribution to scientists, professionals and the general public. It featured a total of 243 seismogenic sources, 61 of which where obtained from geological and geophysical data. All other sources where obtained from the automatic elaboration of macroseismic intensity data at different levels of reliability (Well constrained, Poorly constrained, Deep). Version 2.0 also included:

  • 141 tectonic lineaments selected from the literature, subdivided into transverse or generically oriented with respect to the axis of the Alps and of the Apennines;
  • 41 selected georeferenced fault compilations;
  • several sets of georeferenced “additional data”, such as stress measurements, drainage divides, the trace of thrust fronts, existing seismic zonation models, etc.;
  • 1,252 selected references
  • 450 selected images from the literature
    150 equivalent pages of summaries, comments and open questions.

The Database was described in a volume edited by G. Valensise and D. Pantosti in 2001: Database of potential sources for earthquakes larger than M 5.5 in Italy (DISS version 2.0). Annals of Geophysics, vol. 44, Suppl. 1, with CD-ROM. The complete volume can be downloaded from http://www.annalsofgeophysics.eu/index.php/annals/issue/view/260. The content of the CD can be downloaded using the button below.
DISS 2.0 was regularly updated until 2004, when it was doscontinued in preparation for the publication of the new 3.0 release.
