The study of the statistics of extreme events is an essential first step
in the mitigation of natural catastrophies. This book reviews the
theoretical and practical aspects of the statistics of extreme events in
nature. Topics range from high and low flows, to earthquakes and
volcanic eruptions, land slides, avalanches, windstorms, extreme sea
levels and high waves, forest fires and other disasters that threaten
lives and properties and often cause severe economic losses worldwide.
In many applications it is important to consider extreme events in a
bivariate or multivariate context. Copulas exactly describe and model
the dependence structure between random variables independently of the
marginal laws involved. This approach simplifies the analysis of
phenomena involved and makes it possible to introduce new parameters for
the characterization of the extreme behaviour of a system.
