Risk Analysis 2020 is the 12th International Conference on Risk Analysis and Hazard Mitigation. Risk Analysis 2020 follows on from the other successful meetings in this series, which first started in Valencia, Spain (1998) and continued in Bologna, Italy (2000); Sintra, Portugal (2002); Rhodes, Greece (2004); Malta (2006); Cephalonia, Greece (2008); Algarve, Portugal (2010); the island of Brac in Croatia (2012), the New Forest, home of the Wessex Institute of Technology (2014), Crete, Greece (2016) and Seville, Spain (2018).

The conference covers a series of important topics of current research interests and many practical applications. It is concerned with all aspects of risk analysis and hazard mitigation, associated with both natural and anthropogenic hazards.

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.

The papers presented at the Risk Analysis Conferences cover a variety of topics related to risk analysis and hazard mitigation. They are published as volumes of WIT Transactions on Engineering Sciences, which is widely disseminated around the world in both hardcover and digital formats. Furthermore, all the papers are also archived in the WIT eLibrary (www.witpress.com/elibrary), where they are freely and permanently available to the international scientific community.
