We collected GPS and precise leveling data in Meinong area between 2000 and 2003. We established 20 GPS stations and 16 leveling benchmarks in the area to investigate fault activities. GPS data were processed with BERNESE GPS software V4.2 developed at the Astronomical Institute of the University of Berne and QOCA Version 1.21 developed by Dr. D. Dong at Jet Propulsion Laboratory. We discuss the velocity field, principal strain rate field and the shear strain rate field using the processed GPS data. On the other hand, we processed the precise leveling data according to the first-order level surveying standard (Ministry of Interior, 2001).
