The island of Taiwan lies in a complex [[tectonics|tectonic]] area between the [[Yangtze Plate]] to the west and north, the [[Okinawa Plate]] on the north-east, and the [[Philippine Mobile Belt]] on the east and south. The upper part of the crust on the island is primarily made up of a series of [[terrane]]s, mostly old [[island arc]]s which have been forced together by the collision of the forerunners of the [[Eurasian Plate]] and the [[Philippine Sea Plate]]. These have been further uplifted as a result of the detachment of a portion of the Eurasian Plate as it was [[subduction|subducted]] beneath remnants of the Philippine Sea Plate, a process which left the crust under Taiwan more buoyant.<ref>{{cite web|url=http://www.geo.arizona.edu/~anderson/taiwan/tai_index.html |title= Taiwan |first1=Megan |last1=Anderson |date=2001 |publisher=University of Arizona |access-date=1 August 2010 |url-status=dead |archive-url=https://web.archive.org/web/20101205022356/http://www.geo.arizona.edu/~anderson/taiwan/tai_index.html |archive-date= Dec 5, 2010 }}</ref>

The east and south of Taiwan are a complex system of belts formed by, and part of the zone of, active collision between the North Luzon Trough portion of the [[Luzon Volcanic Arc]] and South China, where accreted portions of the Luzon Arc and Luzon forearc form the [[Haian Range|eastern Coastal Range]] and parallel inland [[Huatung Valley|Longitudinal Valley]] of Taiwan, respectively.<ref>Clift, Schouten and Draut (2003) in ''Intra-Oceanic Subduction Systems: Tectonic and Magmatic Processes'', {{ISBN|1-86239-147-5}} p84–86</ref>

The major seismic faults in Taiwan correspond to the various suture zones between the various terranes. These have produced major quakes. On 21 September 1999, a 7.3 quake known as the "[[1999 Jiji (Chichi) earthquake|921 earthquake]]" killed more than 2,400 people. The [[seismic hazard map]] for Taiwan by the [[United States Geological Survey|USGS]] shows 9/10 of the island at the most hazardous rating.<ref>{{cite web|url=http://www.seismo.ethz.ch/GSHAP/eastasia/asiafin.gif |archive-url=https://web.archive.org/web/20000303055258/http://seismo.ethz.ch/gshap/eastasia/asiafin.gif |archive-date=3 March 2000 |title=USGS seismic hazard map of Eastern Asia |publisher=Seismo.ethz.ch |access-date=30 May 2011 }}</ref>
