Geological Hazards

This module takes a broad look at geological hazards, covering contemporary events, to those that have shaped the Earth over geological time. Specific hazards are addressed, including earthquakes and tsunamis, terrestrial and sub-marine landslides at a variety of differing scales, landslide triggering and principles of run-out, volcanic hazards (eruption styles, plumes and pyroclastic flows) and extreme events which civilisation has yet to witness.

The module explores in depth the fundamental processes involved, and to what extent events can be predicted. Case histories of national and international disasters will be used to illustrate these hazards, with the inherent risks and potential mitigation measures discussed. The module develops a sense of human-place in the geological world, promoting an understanding of how the geological world impacts human society, and what can be done to limit that impact.

Students will be able to describe and explain the processes responsible for the occurrence, recurrence and magnitude of geological hazards, and will gain the knowledge needed to evaluate hazard prediction methods. Additionally, students will gain a critical understanding of risk mitigation strategies, with reference to examples from around the world, and will gain the practical knowledge required to apply simple principles of analysis of slope failure using a variety of natural hazard situations. Students will also be able to demonstrate how simple probabilistic models may be applied to forecasting earthquakes, and discuss the uncertainties inherent in these techniques.
