“…We compare the maximum tsunami amplitudes corresponding to the 100 (

h_{c false(T_{100} false)}

) and 1,000 (

h_{c false(T_{1000} false)}

) year mean return periods. These periods are associated with the tsunami classification “Level 1 ( T 100 )” and “Level 2 ( T 1000 )” adopted by the national government of Japan (Santiago‐Fandiño et al, ). The uncertainty of the rupture area impacts Hong Kong and Kao Hsiung equally, with variations of the tsunami amplitude reaching 9.8% and 26.8% for mean return periods of 100 and 1,000 years, respectively.…”

In this paper, we have conducted a probabilistic tsunami hazard assessment (PTHA) for Hong Kong (China) and Kao Hsiung (Taiwan), considering earthquakes generated in the Manila subduction zone. The new PTHA methodology with the consideration of uncertainties of slip distribution and location of future earthquakes extends the stochastic approach of Sepúlveda et al. (2017). Using sensitivity analyses, we further investigate the uncertainties of probability properties defining the slip distribution, the location, and the occurrence of earthquakes. We demonstrate that Kao Hsiung and Hong Kong would be significantly impacted by tsunamis generated by M W > 8.5 earthquakes in the Manila subduction zone. For instance, a specific M W 9.0 earthquake scenario is capable of producing tsunami amplitudes exceeding 4.0 and 3.5 m in Kao Hsiung and Hong Kong, respectively, with a probability of 50%. Despite the significant tsunami impact, great earthquakes have long mean return periods. As a result, the PTHA shows that Kao Hsiung and Hong Kong are exposed to a relatively small tsunami hazard. For instance, maximum tsunami amplitudes in the assessed locations of Kao Hsiung and Hong Kong exceed 0.32 and 0.18 m, respectively, with a mean return period of 100 years. The inundation hazard in populated areas is small as well, with mean return periods exceeding 1,000 years. Sensitivity analyses demonstrate that the PTHA can be affected by the uncertainties of the probability properties defining the slip distribution, the location, and the occurrence of earthquakes. However, PTHA results are most sensitive to the choice of the earthquake occurrence model.

“…Effects were wide-ranging, with sand and mud mixed with debris littering the coastal areas, extensive contamination by saltwater and other potentially toxic elements (e.g.Komai et al 2012;Santiago-Fandiño and Kim 2015), as well as the radioactive contamination due to the Fukushima Daiichi nuclear power plant (FDNPP) accident (e.g Mimura et al 2011…”
