영문 초록

There are more than thirty continuously recording GPS stations (CORS) have been set up at different geological sites and distributed throughout a 140 km by 140 km area in southern Taiwan beginning since 2000, and the amount of the CORS are still under increasing in this area which is recognized the suture zone between the Philippe sea plate and Eurasia plate. From the year 2000 to the end of 2005, we analyze the daily solutions to obtain the average station velocities before and after the Chengkung earthquake which occurred near eastern Taiwan at 04:38 UTC on 10 December 2003. After considering the effects of the coseismic and postseismic displacements, the difference of the horizontal components reaches 13 mm/year of the average station velocity happened in the east side of the Central Range. To the vertical component, all of the stations are risen which located in the Coastal Range, and the largest difference approaches 20mm/year.
