Abstract
Landslides can generate large tsunamis when falling into lakes and the sea. In order to protect coastal areas and communities we need to predict these events. Mathematical models have become a popular method for this task. However, current models neglect various aspects of either the landslide or the tsunami and predictions can be uncertain and unreliable. In my thesis I developed a model that considers the most important characteristics of landslides, tsunamis and their interaction. The model is tested with a large range of small scale laboratory experiments and with the simulation of a real event. The model gives us new and detailed insights into these catastrophic events. It improves our understanding and our capabilities to predict and mitigate future events.
