This coordination was actively promoted by the National Department of Civil Protection, of which these research institutes are Competence Centers. On these premises, a new project has been set up as an operative research tool based on the best available geological, geophysical and satellite data and know-how, and on a shared and robust modeling workflow. The project is called RETRACE-3D (centRal italy EarThquakes integRAted Crustal model). It has been designed working together, research institutes and Department of
