Uncertainties and risks in geological activities and new ways of their handling

Gyorgy Bárdossy, Janos Fodor

Research output: Contribution to journalArticle


The authors review the main types of uncertainties occuring in connection with geological investigations. The general concepts of handling these uncertainties are outlined. The particular features of scalar, spatial and spatial-temporal evaluations are presented. Limitations of the traditional mathematical approaches - deterministic and probabilistic - applied to geological investigations are discussed. In the second part of the paper new mathematical methods are presented that are more suitable to handle uncertainties than the traditional ones. The fuzzy set theory seems to be one of the most efficient for geological purposes, among these methods. The problems of uncertainty in risk analysis are shortly discussed. Finally, results of test calculations performed by fuzzy arithmetic are presented.
