In addition to the 45 permanent GPS stations currently operated by the Ministry of
Interior, Central Weather Bureau (CWB), Academia Sinica (IES), and other institutions,
150 continuous GPS stations will be newly established in the Taiwan area within the 5-
year period from 2001 to 2005. 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.

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
