Abstract:	摘要： This study first presents the series of peak ground acceleration (PGA) in the three major cities in Taiwan. The PGAs are back-calculated from an earthquake catalog with the use of ground motion models. The maximums of the 84th percentile (mean + one standard deviation) PGA since 1900 are 1.03, 0.36, and 0.10 g, in Taipei, Taichung, and Kaohsiung, respectively. Statistical goodness-of-fit testing shows that the series of PGA follow a double-lognormal distribution. Using the verified probability distribution, a probabilistic analysis was developed in this paper, and used to evaluate probability-based seismic hazard. Accordingly, given a PGA equal to 0.5 g, the annual exceedance probabilities are 0.56, 0.46, and 0.23 % in Taipei, Taichung, and Kaohsiung, respectively; for PGA equal to 1.0 g, the probabilities become 0.18, 0.14, and 0.09 %. As a result, this analysis indicates the city in South Taiwan is associated with relatively lower seismic hazard, compared with those in Central and North Taiwan. 其他題名： Nat Hazards 出版者： Dordrecht: Springer Netherlands 出版日期： 2012-11-01 出處： Natural hazards (Dordrecht), 2012-11, Vol.64 (2), p.1373-1390 資源來源： Agricultural & Environmental Science Collection 版權： Springer Science+Business Media B.V. 2012 版權： 2014 INIST-CNRS 版權： Springer Science+Business Media Dordrecht 2012 識別號： ISSN: 0921-030X 識別號： EISSN: 1573-0840 識別號： DOI: 10.1007/s11069-012-0298-y 識別號： CODEN: NAHZEL
