Welcome to the SAMA group's Extreme Events page.
This theme is coordinated by Philippe Naveau
Currently there is an increasing research activity in the area of geophysical extremes
because they represent a key manifestation of non-linear systems and an enormous impact
on economic and social human activities. Our understanding of the mean behavior in
geosciences and its "normal" variability has been improving significantly during the
last decades. In comparison, extreme events have been hard to study and even harder to
predict because they are, by definition, rare and obey different statistical laws than
averages. In this context, the motivation of this SAMA group is to educate scientists
about the basic principles of Extreme Value Theory and to take advantage of the most
recent advances in this field of statistics and applied probability in order to better
quantity the uncertainty linked to extremes.
