The quake was later identified to have been triggered by the movement of the Chelungpu Fault (車籠埔斷層), leaving a 105km-long surface rupture in central Taiwan, the bureau said. “We started developing the earthquake early warning system in the 1990s. By 1999, the system was able to locate an epicenter about 102 seconds after a quake occurred,” the bureau said. “After the 921 Earthquake, we further upgraded the system by installing more quake detectors across the nation and off the coast, and applying cutting-edge computing technology.
