Following two major landslide incidences in Ireland in 2003 in Galway and Mayo the Geological Survey Ireland established the Irish Landslides Working Group (ILWG) in 2004. It was felt important that it should be a multi-disciplinary team, bringing together various types of expertise which are relevant to landslide studies. This point is often stressed in the international literature on the subject (Brunsden, 1993). The Group includes expertise on geology (Bedrock and Quaternary), geomorphology, geotechnical engineering, planning, and GIS. The participants were drawn from state and semi-state agencies, and also the universities.
