Fra. Si. a national research project supported by the Ministry of the Environment and Land and Sea Protection, develops a coherent set of multiscale methodologies for the assessment and zoning of earthquake-induced landslide hazards. To achieve the goal, the project operates at different geographical, temporal, and organizational scales, and in different geological, geomorphological, and seismic-tectonic contexts. Given the complexity, variability, and extent of earthquake-induced landslides in Italy, operating at multiple scales allows you to (a) maximize the use of available data and information; (b) propose methodologies and experiment with models that operate at different scales and in different contexts, exploiting their peculiarities at the most congenial scales and coherently exporting the results at different scales; and (c) obtain results at scales of interest for different users.

The project defines a univocal and coherent methodological framework for the assessment and zoning of earthquake-induced landslide hazard, integrating existing information and data on earthquake-induced landslide in Italy, available to proponents, available in technical literature and from "open" sources - in favor of the cost-effectiveness of the proposal. The integration exploits a coherent set of modeling tools, expert (heuristic) and numerical (statistical and probabilistic, physically-based, FEM, optimization models). The methodology considers the problem at multiple scales, including: (a) three geographic scales - the national synoptic scale, the regional mesoscale and the local scale; (b) two time scales - the pre-event scale typical of territorial planning and the deferred time of civil protection, and the post-event scale, characteristic of real civil protection time; and (c) different organizational and management scales - from spatial planning and soil defense, including post-seismic reconstruction, to civil protection rapid response. Furthermore, the methodology considers the characteristics of the seismic-induced landslide and the associated hazard in the main geological, geomorphological and seismic-tectonic contexts in Italy.

The project develops methodologies and products for different users and/or users. The former concern methodologies for (i) the synoptic zoning of the hazard caused by earthquake-induced landslides in Italy; (ii) the zoning and quantification of the danger from earthquake-induced landslides on a regional scale; (iii) the quantification of the danger of single deep landslides in the seismic phase; and for (iv) the identification and geological-technical modeling of deep co-seismic landslides starting from advanced DInSAR analyzes from post-seismic satellites.
