GE484 Geofare og skredkartlegging

Innhald og oppbygging

The course gives an overview of different kinds of geo-hazards; landslides, floods, tsunamis, earthquakes etc. We spend most of the time on landslides and explore rock slides, debris- slides and flows, quick-clay slides and snow avalanches. Examples from these are further investigated through practical exercises. An important part of the course is mapping of slides and risk analysis in the field and to evaluate trigger mechanisms for the various slides and other geo-hazards.
