  • Investigation on the Dependence of Tsunami Trace Heights Distribution for Tsunami Source Presumption

抄録

In order to refine previous source estimations of historical earthquake tsunami, the tsunami source from the 2011 Tohoku-oki earthquake tsunami was estimated using the corresponding tsunami trace heights distribution. The tsunami source assessment was performed by applying a sensitivity analysis and evaluating the effects of the heights distribution based on a grid search method. We selected 7 cases of the heights distribution, and minimizing the uncertainty of crustal deformation. The results obtained show that in order to minimize the uncertainty in evaluating the tsunami source, 1) the distribution length of the trace height should be equivalent to the fault length, 2) The interval of the trace points should be 5 % of the fault length or less.
