The Greek Database of Seismogenic Sources is a repository of geological, tectonic and active-fault data for the Greek territory and its surroundings. It represents a complete and modern tool for improving the Seismic Hazard Assessmant (SHA) of the region and a valuable source of information for scientists who want to deal with earthquake scenarios and modelling, geodynamics, active deformation and many more.

GreDaSS is an open-file, continuously updatable, that can accommodate all proposals from multi-field researchers. It is a GIS-based database consisting of several layers, both graphical and metadata ones.

Disclaimer

The Greek Database of Seismogenic Sources (GreDaSS) uses the DISS software of Istituto Nazionale di Geofisica e Vulcanologia (INGV) which is greatly acknowledged.

All related data, texts and elaborations were prepared by the GreDaSS WG. The Database includes a large amount of original and published material on the main seismogenic sources of the broader Aegean Region together with background geological, tectonic and seismological information and it is freely available to all interested parties.

The Database was designed as "work in progress", and as such it is open to continuous additions and improvements. For these reasons and due to its intrinsic nature, the Database cannot be guaranteed to be complete, accurate and updated; in any case it reflects the opinion of the authors and will be subjected to successive revisions.

Although the GreDaSS WG makes every effort to supply the best available information on seismogenic processes, no warranty, expressed or implied, is provided as to the accuracy and reliability of all the data supplied in the Database. Users are cautioned to consider carefully the provisional nature of the data and information before using it for decisions that concern personal or public safety or in relation with business involving substantial financial or operational consequences. Conclusions drawn from this Database, or actions undertaken on the basis of its contents, are the sole responsibility of the user.

No commercial use of the content of the Database and of all related data, texts and elaborations is allowed.

This Database contains data, texts and elaborations prepared by researchers of the GreDaSS WG. The intellectual property rights of the Database are owned by the University of Ferrara.

Tutorial

The Individual Seismogenic Sources are defined by geological and geophysical data and are characterized by a full set of geometric (strike, dip, length, width and depth), kinematic (rake), and seismological parameters (single event displacement, magnitude, slip rate, recurrence interval). Each parameter is then rated for accuracy. (...)
See the ISS DISS Tutorial for further information.

The Composite Seismogenic Sources (formerly Seismogenic Areas) are based on geological and geophysical data and are characterized by geometric (strike, dip, width, depth) and kinematic (rake) parameters. (...)
See the CSS DISS Tutorial for further information.
