Developing seismogenic source models based on geologic fault data in the Euro- Mediterranean area: SHARE mission accomplished?

We present our latest achievements in the making of a seismogenic source model for the Euro-Mediterranean area to be used in P SHA. Data incorporated into the model are stored in a database that is being made available to the public through a web-based GIS application. This effort is being driven by the EU P roject SHARE (http://www.share-eu.org/) with a partnership of 18 institutions, nine of which actively contribute geologic fault data. The aid and collaborative support of a large number of elicited experts was fundamental in gaining insight into active faulting at regional and local scales. In the process of collecting active fault data, we adopted different strategies in different regions of the Euro-Mediterranean area. This approach allowed us to account for the variety of geologic signatures and tectonic environments, and also to give the proper credit to each local scientific legacy. Homogeneity of data was accomplished by using common standards and definitions cross-checked with existing similar models from around the world. As of May 2010, the updated database includes over 400 records of fully parameterized seismogenic sources for a total of about 30 thousand kilometers of faults. These seismogenic sources cover the Euro-Mediterranean area in length and breadth, from Iberia to Greece and from central Europe to North Africa. Mapping of faults in Turkey is in progress with close collaboration with geologists involved in the companion project EMME (http://www.emme-gem.org/). Our collaborative effort is aimed at contributing to a worldwide model that will be hosted by project GEM (http://www.globalquakemodel.org/).
