Accompanying Notes 
 
In June 2015 we released version 3.2.0 of the Database of Individual Seismogenic Sources. This new release features significant improvements with 
respect to the previous versions, both in terms of contents and in terms of its structure. This new release benefits from the developments achieved in the 
construction of the European Database of Seismogenic Faults (EDSF) during the E.C. funded Project SHARE. 
 
As for contents, the new release: 
 
1) features a brand-new layer for Subduction zones (SDZ); 
2) incorporates research results that have appeared in the scientific literature between June 2010 (when the previous version was released) and June 
2015; 
3) includes 5 new Individual Seismogenic Sources (ISS) responsible for significant earthquakes, such as :1) the 3 January 1117 Veronese earthquake, 2) 
the 19 March 1624 Argenta earthquake, 3) the 10 August 1893 Gargano earthquake, 4) the 8 September 1905 Calabria meridionale earthquake, and 
5) the 20 May event of the 2012 Emilia earthquake sequence; 
4) includes 49 new or largey revised Composite Seismogenic Sources (CSS) describing the tectonic activity of: 1) the western Southern Alps thrust 
system, 2) the Trieste Gulf, 3) the "Imperia promontory" off the coast of western Liguria, 4) the central and southern Po Plain, 5) the central 
Apennines extensional system, 6) the external Dinaric thrust system, 7) the Calabrian offshore, and 8) the Sicily Channel; 
5) includes 8 new Debated Seismogenic Sources (DSS); 
6) includes modified parameters for the geometry and kinematics of 32 ISS; 
7) includes modified parameters for the geometry and kinematics of 34 CSS; 
8) features an improved characterization of a number of already existing ISS and CSS. All sources include improved commentaries, new pictures, and 
updated reference lists. 
 
As for the structure, the new release is hosted by a more reliable web-server architecture featuring a totally revamped web-site. Navigation through the 
database is now improved with new web-mapping capabilities, and a new and more informative front-end that allows registered users to submit comments 
and suggestions on specific sources or on any of the contents of the database.
