CFTIlandslides, Italian database of historical earthquake-induced landslides

The CFTIlandslides, Italian database of historical earthquake-induced landslides by Istituto Nazionale di Geofisica e Vulcanologia (INGV), was developed within the project “Multi-scale, integrated approach for the definition of earthquake-induced landslide hazard in Italy”, funded by the Italian Ministry for the Environment, and completed in 2022. The goal of the project was to develop a multidisciplinary approach for assessing the earthquake-induced landslide hazard at national, regional, and local scales, combining existing databases and integrating them with the results from previous projects and research activities. The main objective was the investigation of the central Apennine region. One of the main scopes of the project was locating more accurately all recorded landslides. To this end we focused on the review of historical sources - either newly found or already archived in our database - and on the analysis of scientific articles and technical reports. In summary, our working group reviewed and integrated data relating to historical earthquake-induced landslides that were already included in the CFTI5Med. The combination of the relatively frequent seismic release with a very high landslide susceptibility, makes the Italian territory especially prone to the occurrence of earthquake-induced landslides. For this reason, over the past two years we continued our activity by reviewing all events included in the CFTI5Med for which landslide effects were reported, then we broadened the investigated area to the entire Italian territory.
