GPS Horizontal Velocity Dataset

This table contains GPS station velocities with respect to the South China block. This dataset is derived from GPS data observed during a time period of 1999-2011 under the projects of the Crustal Motion Observation Network of China (CMONC), the Continental Tectonic Environmental Monitoring Network of China, and the National Basic Research Project. These data are first combined with GPS data from the global IGS tracking stations and processed to obtain station positions and velocities with respect to a global reference frame (Wang, 2009). Stations located in the vicinities of strong earthquakes such as the 2008 Wenchuan earthquake also have their coseismic offsets and postseismic displacements (modeled as logarithmic decays) estimated. Regional station velocities are subsequently transformed to the South China reference frame using angular rotation rate of the South China block calculated from the velocities of GPS sites located within the block.
