From: Shallow deformation of the San Andreas fault 5 years following the 2004 Parkfield earthquake (Mw6) combining ERS2 and Envisat InSAR

Figure 4

Across fault profiles, 25 km long and 10 km width, derived from the stacked interferograms (Fig. 3, black rectangle) for each periods and comparison with the GPS data. PA and NA reference the Pacific Plate and the North American plate respectively. Grey dots represent InSAR values in fault strike geometry and black lines their spline interpolation. The red dots present the GPS velocities converted from north-east-up components to LOS and to fault strike geometry in order to allow reliable comparison with InSAR derived estimations. Blue dots present the GPS horizontal fault strike component (case 2). The Root Mean Square Error (RMSE) is estimated between InSAR and GPS (case 2). To avoid data saturation, the vertical scales were adapted accordingly to the data range variability.
