Why?

Landslides are difficult to predict and still often to detect. They cause severe socio-economic constraints in mountainous regions and significant risks to people and infrastructures. These aspects call for sustainable land use planning with innovative mapping and modelling tools. eo4landslides aims to offer on-line services in order to exploit the full potential of satellite data coupled to advanced modeling for landslide hazards assessment in the mountain regions.

Observation

Radar and optical satellite images are increasingly used to support landslide risk management. Interferometry, offset-tracking and change detection methods applied to large volumes of images provide information on ground motion and landslide detection.

Modelling

Mapping terrain susceptibility and hazard to landslides is crucial for land use planning. This requires the construction of reliable landslide inventories, as exhaustive as possible, regularly updated, and providing advanced landslide descriptors.

Information sharing

Landslide products need to be shared between all Disaster Risk Management (DRM) actors, from scientists to private consultants and public authorities, involved at local, regional and national scales.

How?

The quality of satellite-based Earth observation (EO) products has improved considerably in recent years. This, combined with relevant advanced models, supports the development of operational geo-information services and products for landslide risk assessment. eo4landslides integrates three types of interlinked services:

Landslide-Motion

This service is dedicated to the survey of unstable slopes in near-real time and in a systematic mode, and generates landslide ground motion products.

Landslide-Inventory

This service is dedicated to the creation and update of detailed catalogues of landslide events.

Landslide-Hazard

This service is dedicated to the forecast of spatial landslide hazard and landslide evolution scenarios.

eo4landslides is user-tailored and adapted to several scales:

User-driven

The services are user-driven with the engagement of many authorities and stakeholders responsible for landslide Disaster Risk Management.

Scales of analysis

The services are tailored for three analysis scales using specific data and models (Tier 1: regional/basin authority level; Tier 2: municipality level; Tier 3: slope specific level).

Interoperability

The services are accessible online and optimized for high performance computing. They are designed as generic as possible for application in other settings and interoperability with other information systems.

eo4landslides is accessible online on the Geohazards Exploitation Platform (GEP)

More

What?

The services cover the key areas of interest to landslide practitioners, science and DRM communities seeking to better assess landslide hazard and risk.

System Concept

The founding eo4alps-landslides focused on pilot areas in the French, Swiss and Italian Alps

Who?

The eo4landslide app was developed during the eo4alps-landslides project (2021-2023), part of the Alpine regional scientific initiative funded by the European Space Agency and led by an international group of experts.

Partnership

The partners are landslide science experts, consulting companies in geological risks, InSAR processing and IT, and geological surveys.

Leading experts

The consortium is led by Dr Jean-Philippe Malet with the support of Dr Clément Michoud.

ESA regional initiatives

The European Space Agency has impulsed several regional initiatives to promote and foster the use of satellite data in society.
The Alps initiative (eo4alps) is sponsoring actions on snow, glaciers, air quality, ecosystems, and, in this case, landslides.
