Abstract
In order to carry out disaster reduction efficiently, it is important to know well the probability of the damage, it means the risk assessments due to disasters. Two types of method on tsunami risk assessments were compared for the Ibaraki prefecture coasts where not many tsunamis have arrived, one is using the logistic tree for probabilistic occasion, magnitude of landslips and so on, and the other is extreme statistics analysis from the tsunami records. The results of probabilistic inundation map, causality and damage of houses show that large uncertainly remains.
