GE484 Geohazards and landslide mapping

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 falls and rock avalanches, 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 landslide deposits in the field.

Learning Outcome

Knowledge

• 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.

Skills

• Students are able to identify and interpret different kinds of traces from landslides in the field.

General competence

• Students are able to investigate and map previous slide events in an area and to discuss the risk for future events.
