Current events help to emphasise the importance of the analysis and management of risk to planners and researchers around the world. Natural hazards such as floods, earthquakes, landslides, fires and others have always affected human societies. The more recent emergence of the importance of man-made hazards is a consequence of the rapid technological advances made in the last few centuries. The interaction of natural and anthropogenic risks adds to the complexity of the problems. Presented at the 12th International Conference on Risk Analysis and Hazard Mitigation, the included research works cover a variety of topics related to risk analysis and hazard mitigation, associated with both natural and anthropogenic hazards.
