- Abstract:
- Firstly,we choose 6 sites—Zhoushan,Ningde,Xiamen,Hongkong,Haikou,and Gaoxiong in the southeastern coastal areas in China as the research samples.Then we suppose the Manila trench subduction zone and the Ryukyu trench subduction zone are the potential sources of the earthquake-induced tsunami.We estimate the uncertainty of the magnitude by the Generalized Extreme Value method and the Generalized Pareto Distribution.By probabilistic statistics,we get the predominant distribution of the focal depths of the potential earthquakes in these two subduction zones.By fitting the function of slip angle's distribution and by coupling the uncertainty of magnitude,focal depth,and slip angle,we estimate that the potential earthquakes in the Manila trench subduction zone and the Ryukyu trench subduction zone would induce tsunamis whose wave height exceeds 0.4 m at the 6 sites in next 30,50 and 100 years.
