Abstract

We discuss a method to estimate the seismic tsunami hazard coupling uncertainty of upper magnitude limit and focal depth in this paper. The method of estimating uncertainties of upper magnitude limit and focal depth is discussed. Manila trench and Ryukyu trench subduction zones are chosen to be the potential seismic tsunami source areas and five off-shore sites near to Chinese southeast coastal region are used as site-specific. The uncertainty of upper magnitude limit is estimated by generalized extreme value method and the uncertainty of focal depth is calculated by probabilistic statistics method. Under the assumption that earthquake with the upper magnitude limit occurred in Manila trench and Ryukyu trench subduction zone, the seismic tsunami hazards that exceed 0.5m of tsunami wave height at five site-specific are estimated.
