A landslide susceptibility model and map (LSMM) predict where landslides are expected to occur or be more or less abundant based on terrain conditions, including the local morphological, geological, and land use settings. Using different colours, a landslide susceptibility map shows the predicted levels of landslide susceptibility in a region. LAMPRE has developed specific software to model landslide susceptibility and to produce the associated maps using statistical modelling tools.
Software developed by LAMPRE allows preparing landslide susceptibility models and maps at various geographical scales and for areas ranging from very small (a few slopes) to much larger (entire catchments or regions), provided sufficient geographical information on the location of landslides and on the local morphological, geological and land use setting is available.
Using software developed by LAMPRE, LSMMs can be prepared whenever new landslides or environmental (e.g., morphological, geological, land use) data is available for a region of interest. When a new event inventory map is prepared after a landslide-triggering event, existing LSMMs can be produced.
Civil Protection authorities use LSMMs in landslide regional or national early warning systems, and to improve their response capacity.
Planning & development authorities use LSMMs to identify landslide prone areas and to zone a territory accordingly.
Transportation authorities & utility managers use LSMMs to predict the potential impact of landslides on transportation or utility network, and for improved maintenance strategies.
Agricultural & forest agencies use LSMMs to identify landslide prone areas, for improved agricultural and forest management.
Scientists use LSMMs to predict the expected climate and environmental changes on landslide abundance and activity.
LAMPRE prepares LSMMs at scales ranging from 1:100,000 (smaller scale) to 1:25,000 (larger scale) in periods from hours to days after the landslide inventory and terrain (e.g., morphological, geological, land use) data become available. The quality of the landslide and terrain information controls the quality of the LSMMs. LAMPRE can use independent landslide information (e.g., an event landslide inventory map) to validate the LSMMs.
