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 regional and national scale.
The core objects of DISS are:
Notice that individual and composite seimogenic sources are two alternative models of crustal seismogenic faulting. 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 seismic hazard.
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 accessed through an alphanumeric user interface or a map viewer in your web browser. Alternatively, users can download the "kml" file to display and navigate the database from within the Google Earth software. Simply follow this link to start navigating.
DISS presently contains information on seismogenic faulting in the Italian territory and its surrounding regions but it is structured to include data from anywhere. The area in which we engage ourselves to provide the most complete information and substantial updates (the database area of relevance) is shown in the map viewer.
DISS content is ready to use, yet it may require some further manipulation of fault data by analysts and modelers depending on its application. Depending on the version, data are available in various GIS formats for seamless download.
