This earthquake was caused by the Juisui Fault with a vertical movement of 70 centimeters (28 in). [5] [6] The Juisui Fault is a segment of the 150 kilometers (93 mi) long Longitudinal Valley Fault, which is a left-lateral fault with a reverse component. [7] The boundary between the Eurasian Plate and the Philippine Plate lies along the Longitudinal Valley Fault. [8]

The island of Taiwan was formed approximately 4 to 5 million years ago at a convergent boundary between the Philippine Sea Plate and the Eurasian Plate. In a boundary running the length of the island and continuing southwards, the Eurasian Plate is sliding under the Philippine Sea Plate. In the northeast of the island, the Philippine Sea Plate slides under the Eurasian Plate. Most of the island comprises a huge fault block tilted to the west.
