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.

A Landslide Inventory Map (LIM) shows the location, spatial extent and type of landslides in a region. LAMPRE has advanced the methods available to prepare and update LIMs through expert visual interpretation of very-high resolution stereoscopic satellite images.
The methods developed by LAMPRE can be used to prepare a LIM anywhere stereoscopic satellite images of adequate quality are available. The methods work in all landscapes and climatic regions, and are applicable for areas ranging from a few to several hundreds of square kilometres. The methods developed by LAMPRE can be used in combination, or as an alternative, to the traditional methods used by geomorphologists, which are based on the visual interpretation of stereoscopic aerial photographs.
LAMPRE can prepare or update a LIM whenever new stereoscopic satellite imagery becomes available for an area of interest. The time for the preparation or the update of a LIM varies from a few days to several months, depending on the extent and the complexity of the study area. LAMPRE can prepare multi-temporal LIMs by periodically systematically updating the LIM for the same area.
Civil Protection authorities use LIMs in the aftermath of an event for improved rescue and recovery operation.
Planning & development authorities use LIMs to identify areas affected by landslides, and so that dangerous areas can be avoided.
Transportation authorities & utility managers use LIMs to evaluate the impact of landslides on transportation or utility networks.
Agricultural & forest agencies use LIMs to assess the impact of landslides on crops and forests.
Scientists use LIMs for erosional studies and to determine the statistics of landslide areas.
LAMPRE prepares LIMs at scales ranging from 1:25,000 (smaller scale) to 1:10,000 (larger scale) in periods ranging from days to months, depending on the extent and complexity of the study area. To prepare a LIM, LAMPRE needs stereoscopic satellite images or aerial photographs, and delivers the LIM in raster and vector formats.

The study area is located in Umbria, central Italy, where climate is Mediterranean and rainfall occurs mostly from October to December and from March to May. In the region crop out sedimentary rocks pertaining to the Umbria-Marche stratigraphic sequence, Lias to Eocene in age, overlaid by lake and fluvial deposits, lower Pliocene to Quaternary in age, and by fluvial deposits of Recent age.
The study area is located along the northeastern part of Sicily, Southern Italy, in the Peloritani and the Nebrodi ranges. Climate is Mediterranean with hot and dry summers and precipitation falling mostly in the period from October to January. Elevation ranges from sea level to 1847 m. Sedimentary and crystalline rocks predominate, including limestone, dolomite and flysch deposits, Jurassic to Pliocene in age, and crystalline rocks Paleozoic to Tertiary in age.
The island of Majorca (Spain), located in the western Mediterranean, has a variety of different geomorphological domains, most prominently the Tramuntana Range (1,100 km2) in the north-western part of the island. The steep topography of this chain, which is linked to its geological complexity and Mediterranean climate, determines intense slope dynamics with the consequent movements of all categories.
The study area comprises two zones both located in the Swiss Alps: (i) the Mattervalley, going up from Visp in the bottom of the Rhonevalley to Zermatt, and (ii) the St. Moritz - Engadin valley area. In the Mattervalley area mainly metamorphic rocks (schists and gniesses) crop out. In the valley there are numerous instable slopes, including some densely populated regions prone to landslides.
The Kaohsiung region is almost entirely covered by the 3,242 km2 Kaoping watershed, originated by the Kaoping river, the longest in Taiwan. The elevation ranges from the highest peak of the Central Mountain Range at 3,952 m a.s.l. to the basin outlet at 0 m a.s.l.. Ninety percent of annual precipitation (~2,800 mm) falls in the wet season (May to September) (Water Resource Agency, 2008).
The study area is located in the Cerros de Escazú, province of San José, which is a mountain range in central Costa Rica located southwest of the city of San Jose. The climate is predominantly tropical and rainfall occurs mostly from May to November; abrupt changes between sunny and rainy weather are common. It borders the Central Valley to the south, and along with the Cedral massif forms the Fila de la Candelaria, which is considered the northernmost part of the Cordillera de Talamanca.
The study area is located in upper part of Valle de Tena, the headwaters of the Gállego River in the central Spanish Pyrenees (Huesca), where climate is characterized by a marked seasonality, classified as of the mediterranean mountain type with Atlantic and Continental influences. The average annual precipitation is around 1500 mm with rainfall concentrated mainly in spring and autumn, followed by winter and with punctual intense convective storms during the summer.
The Pogliaschina valley extends for about 11 km2 in the Municipality of Borghetto Vara in the Liguria Region. The Pogliaschina torrent and the Cassana torrent flow into the Vara River close to the Borghetto Vara village. In the Pogliaschina valley crop out sedimentary rocks mainly belonging to the M. Gottero sandstones formation (Upper Cretaceous and Paleocene) with minor outcrops of the Macigno and Scaglia Toscana formations.
