碩士 / 國立中央大學 / 水文與海洋科學研究所 / 106 / The purpose of this research contains two parts: first, assessing the potential threats of the tsunamis of 1960 Chilean Tsunami and 1867 Keelung Tsunami, second, locating the latter event. Both parts involve COMCOT (Cornell Multi-
grid Coupled Tsunami Model) integrated with IIA (Impact Intensity Analysis), and TATA (Tsunami Arrival-Time Analysis), which accuracy has been proved
by applying to the scenarios for Yap Trench and Mariana Trench. Through applying the methods of IIA and TATA, it has been found that the impact in Taiwan is not significant due to the source of 1960 Chilean Tsunami. The cross- validation shows that the height of tsunami at Keelung would have increased 70%, while the one at Hilo City would increased 50%, if the souse of 1960 Chilean Tsunami had been shifted 500 kilometers toward north referred to the source. Results of IIA at Jinshan and Keelung in northern Taiwan were used to design scenarios. It was found that the wave heights at Chilung Valley, Mien-Hua Canyon and the unnamed submarine volcano is located in the northeast of the second nuclear plant, concur with the literature. In addition, it reveals also potential tsunami hazard to the north of Taiwan caused by the movements in Hoping Basin. The map obtained by the comparison of linear and nonlinear IIA results is used to understand the distribution of nonlinear effects of the complex bathymetry in northern Taiwan.
