Abstract
Consequences of catastrophic rock slope failures (i.e. rock avalanches) are usually of large magnitude as they can run across large areas and can trigger secondary processes (e.g. displacement waves, river damming, valley flooding) that can produce large economic and life losses. Early detection of rock slope instabilities and definition of their hazard zones can help society to reduce the impact of these catastrophic failures. This contribution presents the results of the analysis done for an area in the Manndalen Valley, northern Norway. The site has been monitored by remote sensing techniques and the possible runout areas of a catastrophic failure have been defined using numerical modeling for three volume scenarios. Results show that the hazardous area is limited to the eastern valley flank and part of the valley bottom with no secondary processes triggered by the rock avalanche event.
