    Abstract: 本研究係探討台灣沿海因地震所引起之海嘯危害,應用隨機滑移模型
    譜的冪律行為。在海嘯危害分析中,依k-square model 來產生多組的隨機滑
    嘯危害度分析。;We conduct probabilistic tsunami hazard analysis (PTHA) of Taiwan
    region for earthquake sources (the maximum event) in the south part of the
    Ryukyu trench and present the annual rate of tsunami wave heights exceeding z.
    Stochastic model describes uncertain and heterogeneous slip distributions on the
    fault. The values of slip distribution are following the boundary of heavy tail for
    the 2D white noise (X) and that also makes the power law deviate to the k square
    model. In PTHA, we synthesize patterns of differently complex and
    heterogeneous slip distributions induced the vertical seafloor displacements by
    stochastic model. The results clearly show the tsunami prorogation is affected
    along with the slip distribution pattern changing. That means the behavior of
    real tsunami is not the same even under the same conditions and suggest we
    ignore the possibility of wave height as estimating the tsunami hazard before
    and have a chance to underestimate. This study supplies a more realistic method
    of the tsunami hazard analysis and obtains more information.
