Internal contact person: Mauro Cardinali

An Event Landslide Inventory Map (ELIM) shows the location and extent of landslides caused by a specific natural trigger, such as an intense rainfall event, a period of prolonged rainfall, a rapid snowmelt event, or an earthquake. The methods and tools developed by CNR-IRPI allow preparation of an ELIM anywhere recent landslides have left discernible signs.

Methods and technologies

CNR-IRPI prepares ELIMs at scales ranging from 1:25,000 (smaller scale) to 1:5000 (larger scale) in periods ranging from hours to months after the delivery of the high resolution (HR), very-high resolution (VHR) optical satellite images and/or stereo and ortho aerial photo. CNR-IRPI uses photo-interpretative and semi-automatic approaches to classify the images. CNR-IRPI can also prepare eLIM through extensive field surveys. eLIMs are delivered in raster and vector formats.

Civil Protection authorities use ELIMs in the aftermath of an event for improved rescue and recovery operation.

Planning & development authorities use ELIMs to identify areas recently affected by landslides, and avoid dangerous areas.

Transportation authorities & utility managers use ELIMs to evaluate the impact of landslides on transportation or utility network.

Agricultural & forest agencies use ELIMs to assess the impact of landslides on crops and forests.

Scientists use ELIMs to prepare multi-temporal inventories useful for erosional studies, and to determine the statistics of landslide areas.
