   Disaster- and Risk Assessment from Extreme Value Statistics 

by Reinhart Kühne




More than 50 years of daily water level recordings of the Danube river are the basis for precise water level fluctuation statistics, paving the way for a statistical analysis of natural disasters like floods or earth quakes. Starting with models for the dynamic time evolution of the characteristic variables including fluctuating forces the temporal development of the probability distribution for a certain water level height, a certain seismic elongation or another disaster variable is derived and compared with measurements. Applications to stock prices at the stock exchange or to traffic breakdowns and congestion formation as man made disasters are given as well. The calculation of the time when reaching a critical value for the first time (first passage time) turns out to be the key element for applying extreme value statistics to disasters. Besides this determination of the first passage time distribution, the maximum value distribution finally completes the investigations.
