大阪湾内におけるリアルタイム津波予測手法の検討

抄録

There is a little time to react until the tsunami arrival in each port in Osaka Bay in case of Nankai Earthquake occurrence. Therefore, it is possible to take precautions against the tsunami if appropriate tsunami information can be obtained. In this study, the real-time tsunami forecast system which can complement the forecast of the Meteorological Agency is examined. The real-time tsunami forecast method which is proposed in this research forecasts the tsunami that reaches in Osaka Bay 1 to 1.5 hours later by using the observed data outside the bay. The Shirahama Observation Tower in Tanabe Bay, Wakayama is considered as one of the offshore tsunami observation facilities. As a result of the examination, the accuracy of this method using the observed data was well and usefulness was confirmed.
