This report presents investigations, analyses and displacement measurements made between 2006 and 2012 on 131 unstable or potential unstable rock slopes in Møre og Romsdal County (Western Norway). An extract of this report is available in Norwegian (NGU rapport 2013.053).These investigations are part of the national plan for mapping of unstable rock slopes in Norway from the Norwegian Water Resources and Energy Directorate (NVE) and NGU. A total of 245 sites are known in Møre og Romsdal, but only 77 sites are classified as unstable rock slopes that are relevant for this project by being large enough to create either a rock avalanche or a displacement wave if impacting a water body. The remaining sites are classified either as potential unstable rock slopes (29 sites), not unstable rock slopes (91 sites) or have not yet been visited (48 sites) and have thus unknown status.
