The 50 new stations are going to be evenly distributed around the Taiwan Island. The other 100 stations will be densely deployed near the active faults and potential earthquake source area. In 2001-2002, 60 new stations were set up and in operation as a collaborated effort between the CWB and IES. These stations are distributed in the Chu-Miao, Chia-Nan, Hua-Tun areas and central Taiwan. 301 Preliminary analysis of the continue GPS data from new stations established in 2000-2001 shows that significant postseismic displacements were found in the hanging wall of the Chelnngpu fault. A dense continuous GPS array in Taiwan will be completed by the end of 2005. The enormous continuous GPS data collected by the array will give us the unprecedented opportunity to study the crustal deformation of different space and time scales. The near real time spatial and temporal variations of crustal strain can be realized and their correlation with seismic activity will be studied. In the event of a major earthquake, the continuous GPS array provides the precise observations on the preseismic, coseismic, and postseismic deformations. Then we
