The Taichung Domain was moving northwestwards before the 1999 Chi-Chi earthquake: in the footwall of Chelungpu Fault the slip rate was ~10 mm/yr, while in the hanging wall the rate increased eastwards up to 10-30 mm/yr. Two years prior to the earthquake, in the footwall of Changhua Fault the deformation direction changed from WNW to almost due N, and velocity gradient changed from increasing northwards to increasing eastwards, suggesting possible precursor of a large earthquake.
