Figure 1

The observed (black arrows) and predicted (magenta arrows) coseismic displacements at the 847 GPS sites. (a) and (b) Horizontal and vertical displacements, respectively, at 474 sites within 600 km epicentral distance. (c) and (d) Horizontal and vertical displacements, respectively, at the other 373 sites with epicentral distances from 600 to 1,000 km. The black rectangle denotes the boundary projection of the fault plane and the black pentagram indicates the epicenter (the same in subsequent figures).
