FAQ for Earthquake

19. What is the classification of earthquake-resistant standards for buildings in Taiwan?

After the Chi-Chi earthquake on September 21 of 1999, the Construction and Planning Agency, Ministry of the Interior, revised the part for earthquake-resistant construction design in the Taiwan construction technology regulation according to the most updated strong ground motion data available in December 1999 (MOI Tai-88-Nei-Ying-Zih-8878473). According to the regional seismic horizontal acceleration coefficient, earthquake areas are divided into Earthquake Division A and Earthquake Division B, the corresponding acceleration coefficient is 0.33g and 0.23g, respectively. The seismic regions include the municipality, the county (city), and the township (town, city), and are tabulated as in the following table:

Earthquake Division A Earthquake Division B
Yilan County, Hsinchu City, Hsinchu County, Miaoli County, Taichung City, Changhua County, Nantou County, Yunlin County, Chiayi City, Chiayi County, Tainan City, Hualien County, Taitung County. Keelung City, Taipei City, New Taipei City, Taoyuan County, Kaohsiung City, Penghu County.
Kaohsiung City Qishan District, Sanmin District, Liugui District, Neimen District, Jiaxian District, Shanlin District, Meinong District, Taoyuan District, Maolin District. Kaohsiung City Fengshan District, Gangshan District, Dashe District, Daliao District, Dashu District, Renwu District, Tianliao District, Yong-an District, Alian District, Linyuan District, Ziguan District, Niaosong District, Jiading District, Luzhu District, Hunei District, Yanchao District, Qiaotou District, Mituo District.
Pingtung County Hengchun Township, Jiuru Township, Neipu Township, Ligang Township, Checheng Township, Mudan Township, Changzhi Township, Laiyi Township, Taiwu Township, Gaoshu Township, Chunri Township, Shizi Township, Majia Township, Wanluan Township, Manzhou Township, Wutai Township, Yanpu Township, Linluo Township, Sandimen Township. Pingtung County Pingtung City, Donggang Township, Zhutian Township, Linbian Township, Jiadong Township, Fangshan Township, Fangliao Township, Nanzhou Township, Kanding Township, Liuqiu Township, Xinpi Township, Xinyuan Township, Wandan Township, Chaozhou Township.

Kinmen and Matsu do not belong to either division; however, they would best fit Earthquake Division B according to the earthquake horizontal acceleration coefficient.
