Estimation of tsunami or storm surge height is usually based on the historical maximum record or an assumed maximum value. This study proposes probabilistic evaluation procedure of storm surges employing stochastic typhoon model and applies to Suruga Bay, Japan. Typhoon tracks passed the target area are extracted from synthetic typhoon track data set for 5000 years generated by the stochastic tropical cyclone model. Occurrence probabilities of storm surge height are estimated along the coast in Suruga Bay. The estimated hazard curves of storm surge can estimate the return period of the design storm surge in each regional coast.
