Abstract
Overlap of several hazards: storm surge, high waves, river runoff and flood etc. accumulates risk and its prediction will become troublesome. The importance of statistical distribution of joint occurence is now increasing in disaster risk reduction plan, but it is hard to say that bivariate GP distribution has been developed for those applications. Though GP distribution requires a suitable threshold to extract the extremes of hazard magnituides, the methods of threshold choice has not enough discussed for bivariate extremes. This reserch focuses on the correlation coefficient of occurrence rates, whose efficiency is examined through the observed data of wind velocities at two cities in Germany.
