A non-extensive approach to risk assessment
Technological Educational Institute of Crete, Department of Natural Resources and Environment, Geophysics and Seismology Laboratory, 3 Romanou str., Chania, 73133, Crete, Greece
Abstract. We analytically estimate the risk function of natural hazards (earthquakes, rockfalls, forestfires, landslides) by means of a non-extensive approach which is based on implementing the Tsallis entropy for the estimation of the probability density function (PDF) and introducing a phenomenological exponential expression for the damage function. The result leads to a power law expression as a special case and the b-value is given as a function of the non-extensive parameter q. A discussion of risk function dependence on the parameters of hazard PDF and damage function for various hazards is given.
