GE484 Geohazards and landslide mapping
Course description for academic year 2021/2022
Contents and structure
The course gives an overview of different kinds of geohazards; 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 geohazards.
Learning Outcome
- Students have a broad and general understanding of tsunamis, earthquakes, floods and landslides and how these can influence human society.
- Students gather detailed knowledge of different kinds of landslides; the slide process and trigger mechanism.
- Students are able to identify and interpret different kinds of traces from landslides in the field.
- Students are able to investigate and map previous slide events in an area and to discuss the risk for future events.
