It is necessary to establish a consistent evaluation scheme for estimating the height of tsunamis triggered by submarine landslides, since a standard framework for evaluation has not been established even though several models for calculation have been proposed and applied in practice. In this study, we propose a method of evaluating the height of a tsunami triggered by a submarine landslide using three schemes -the KLS model, Watts model and modified-KLS model for calculation, by setting the

As a result of the comparison of the tsunami height evaluation produced by each model, it was suggested that, comparing the experimental result and those of other methods, a safe-side evaluation result might be obtained by the KLS model, applying the maximum sliding velocity calculated by the Watts model as a parameter.
