Cathastrophic Hazard Events

Geohazards, such as earthquakes, landslides, volcanic eruptions and flank collapses, and derived tsunamis, can have devastating effects on populations, economies and landscapes around the world. Understanding and developing effective and sustainable strategies to assess the risks and minimise the impacts of these hazards is and will increasingly become a major task for geoscientists. This module provides basic knowledge about the underpining geoprocesses. Such knowledge is essential in order to be able to develop sustainable strategies in the future.

1) introduction and overview about submarine geohazards
2) earthquake mechanics and risk maps
3) volcanic flanc eruption and flank collapse
4) submarine landslides: triggers and slope stability analyses
5) tsunami: generation and impact, risk assessment

Various exercises for the individual topics
