Taiwan has 33 active faults and four suspected faults that have not been documented, Kuo said.

Known faults in northern Taiwan include the Jinshan and Shanjiao faults, while noted faults in central Taiwan include the Dunzejiao and Chelungpu faults, Kuo said.

Both the Chelungpu Fault and the Meishan Fault in southwestern Taiwan are 100 km long, Kuo said.

A 100-km-long fault can cause earthquakes exceeding magnitude 7, Kuo said.

「The longer the fault, the stronger the earthquake,」 Kuo said, adding that the length of the blind fault in Jenai may also span 100 km.
