Geodetic observation, model prediction and residuals. (a), (d) and (h) show the observed InSAR displacements. (b), (e) and (i) show the model predictions. (c), (f) and (j) show the corresponding residuals. (k) Black arrows are the observed GPS site displacements; red arrows represent the model predictions. (l) shows the residuals of GPS data, error ellipse indicates 95% confidence level. The red star corresponds to the epicenter of the Muji earthquake (U.S. Geological Survey [USGS]), and the black line indicates the surface trace of our source model.
