Activities

The European Landslide Expert Group has produced guidelines for delineating areas at risk of landslides in Europe using harmonised approaches and common thematic datasets, as suggested by the EU Thematic Strategy for Soil Protection and the related Proposal for a Soil Framework Directive. Such approaches initially focus on landslide susceptibility mapping and are based on Tiers. These consist of hierarchically-ordered, geographically-nested approaches whereby areas identified as of high susceptibility to landslides in the initial, synoptic-scale Tier (Tier 1) are subsequently evaluated and mapped at higher resolution in successive Tiers.

The Group has additionally developed models for landslide susceptibility assessment at European scale (Tier 1) and national scales (Tier 1 and 2) using available landslide conditioning factor datasets and landslide inventory data. As a result, landslide susceptibility maps have been produced for Italy and France, as well as a first version of the European Landslide Susceptibility Map (ELSUS1000 v1), released on 15 February 2013, and a second version (ELSUS v2) on 12 February 2018 (see Data and Publications sections below).

Current work focuses on (1) evaluating the accuracy of ELSUS v2; (2) testing statistical approaches for landslide susceptibility assessment in selected areas of Europe where landslide inventory data are more complete; and (3) assessing landslide susceptibility at pan-European and national scales in selected countries separately for major landslide types. These activities are carried out in collaboration with some members of the European Centre on Geomorphological Hazards (CERG) and of EuroGeoSurveys’ Earth Observation and Geohazards Expert Group, as well as with other European landslide experts.

Data

To get access to the new European Landslide Susceptibility Map ELSUS v2, including ancillary spatial datasets and metadata, please compile the Request form; instructions on how to download the data will then follow. 

Please note that ELSUS v2 shows larger geographical coverage, higher spatial resolution and higher prediction model performance than the former version ELSUS1000 v1. The latter has been removed from ESDAC following publication of ELSUS v2.

Meetings

A number of meetings and hands-on workshops have been held in Ispra, Hannover, Vienna, Berlin and Perugia, including two plenary meetings.

1st Plenary Meeting

On 23-24 October 2007 a meeting on Guidelines for Mapping Areas at Risk of Landslides in Europe was held at JRC, Ispra, in support of the EU Thematic Strategy for Soil Protection and the related Proposal for a Soil Framework Directive, with main focus on the task of “identification of areas at risk of landslides” in EU Member States. See the Agenda and the List of Participants.

Main terms of reference

1. Objectives

  • To provide scientific and technical advice and assistance to the European Commission's Joint Research Centre (JRC) on its landslide-related scientific and technical activities in support to EU soil policy making by the relevant Commission services, with main focus on the EU Soil Thematic Strategy, through collaborative discussions and research.
  • To liaise and build partnerships with other international organizations and associations dealing with landslide hazards (e.g. EuroGeoSurveys, International Consortium on Landslides (ICL), European Centre on Geomorphological Hazards (CERG), ESA, UNESCO, UN-ISDR, IUGS, IAEG, IAG, EFG, etc.).
  • To promote and participate in international initiatives and research projects regarding mainly landslide prevention and mitigation, and geospatial information systems together with other partners.
  • To produce, or contribute to, scientific and policy publications of the European Commission and other international bodies regarding landslides, and to joint articles in scientific journals and conference papers. Likewise, to organise specific sessions in international conferences.

2. Membership and operation

  • Membership will combine expertise and different views from geological surveys, research organizations and universities in Europe.
  • Membership is open to European landslide experts,.
  • Initial membership will include a relatively small number of members from the above-mentioned types of institutions, while being extensible to additional and/or temporary members in order to cater for specific activities upon requests from European Commission services, including JRC, and possibly from international and Expert Group members' organizations.
  • Membership will be compatible with that of other working groups.
  • Work duplication with that of other committees or working groups should be avoided. Collaboration with them should be pursued when necessary.

3. JRC support to the Group operation

In order for the Expert Group to meet its objectives, the JRC will:

  • Provide financial support for travelling and lodging to Group members participating in Group meetings. These will be held at JRC's Ispra site or, alternatively, at a member's organisation site or at an international conference venue.
  • Create and maintain a dedicated section on the Group activities and research results within the European Soil Data Centre
  • Produce and distribute limited hardcopy editions of the main Group reports.
  • Search for possible additional financial support to the Group operation from JRC and other Commission services.
