Welcome to the portal of the Geomorphology group at CNR IRPI in Perugia, Italy. We are a team of geologists, engineers and physicists interested mostly in landslides, landslide hazards, and the definition of the associated risk. We do research on a number of topics, including:

• landslide mapping at different scales and in different physiographic environments
• analysis of landslide types and patterns in relation to geological settings
• landslide susceptibility, hazard, vulnerability and risk assessments, at different scales
• validation of landslide inventories, and susceptibility and hazard maps and models
• acquisition and use of information on historical landslide and flood events
• identification of rainfall and hydrological thresholds for possible landslide occurrence
• spatially distributed rock fall modelling
• analysis of landslide sizes (number, area, volume, energy)
• analysis of time series of landslide events
• remote sensing (Laser, Optical, DInSAR, GPS) for landslide identification, mapping, and monitoring
• geographical databases and content management systems
• dissemination of information on geo-hydrological hazards and risk

On these and other topics, we have published more than 90 papers, reports and maps, some of which are available through this site. We manage a repository of data on historical landslide and flood events in Italy (SICI), and a world-wide database of rainfall thresholds for the possible occurrence of landslides. We are involved in European and National research projects dealing with natural hazards, and their consequences.

We maintain active national and international collaborations, among others, with the Geomorphology group at the Lamont-Doherty Earth Observatory of Columbia University, New York (US), the Environmental Monitoring and Modelling Research Group at Kings College, London (UK), the Department of Earth System Analysis of the Faculty of Geo-Information Science and Earth Observation (ITC), Enschede (NL), the Max Planck Institute for Dynamics and Self-Organization, Göttingen (DE), the Geological Survey of Israel (GSA), Israel, the United States Geological Survey (USGS), USA, the NASA Goddard Space Flight Center Hydrological Sciences Branch, USA, the Department of Geography of the National Taiwan University, Taipei, and the Kainan University (TW), the CNR IREA (Institute for Electromagnetic Sensing of the Environment), Naples, the CNR IMAA (Institute of Methodologies for Environmental Analysis), Potenza, the CNR IFAC (Institute af Applied Physics Nello Carrara), Florence, the Department of Earth Sciences of the Perugia University, the Department of Earth Sciences and the International Research School of Planetary Sciences (IRSPS), of the University G. D'Annunzio, Chieti, and the Department of Environmental Science, of the University of Siena.
