Earthquakes in Taipei

Taipei sits in a region of high seismic risk, part of one of the most tectonically active zones on the planet where the Philippine Sea plate collides with Eurasia. The city occupies a soft-sediment basin ringed by mountains, and the active Shanchiao Fault runs along its western edge, capable of generating a strong local earthquake directly beneath the metropolis. The basin's loose deposits can amplify ground motion significantly, a factor that shapes the city's demanding building codes.

Although Taipei has been spared a direct catastrophic hit in modern times, the island's vulnerability was made devastatingly clear by the magnitude 7.6 Chi-Chi earthquake of 21 September 1999 in central Taiwan, which killed around 2,400 people. That distant quake still caused deaths and a notable building collapse in the capital, and the powerful magnitude 7.4 Hualien earthquake of April 2024 again swayed Taipei's towers. These events keep earthquake preparedness at the centre of civic life in the Taiwanese capital.
