Risk assessment of a tsunamigenic rockslide at Åknes

This paper introduces the application of a simple and practical method for estimating the risk associated with a potential tsunamigenic rockslide, by assessing quantitatively hazard, vulnerability, and elements at risk. The proposed method introduces empirical relations between the risk components and illustrates the uncertainty propagation through the steps in the risk analysis. A case study is presented, showing the applicability of the method for estimating the risk associated with the tsunamigenic Åknes rockslope in Stranda municipality in western Norway. Results show, preliminary risk estimates that will be of significant value for future policy and decision making. Copyright Springer Science+Business Media B.V. 2011
