Fig. 1 – East (A) and up (B) components mean velocity maps of the Gargano area with main tectonic features. In panel A, the blue colors represent positive velocities (eastward) and in red the negative ones (westward). In panel B, the blue colors represent positive velocities (upward) and in red the negative ones (downward). Black flags represent the GPS permanent stations and the red line is the trace of the velocity profiles (2.5 km buffered) shown below. In panel C, D and E the mean LOS velocity maps from (C) ascending track 156, (D) descending track 206 and (E) descending track 435 (from Pezzo et al. , 2012). Positive velocity values (blue colors) indicate ground movement toward the satellite along the LOS direction (inclined 23 from the vertical), negative ones (red colors) indicate the opposit. In red we show the DFS system trace; other faults in the region are in black. Black triangles indicate the reference point; black boxes mark the ~20 km buffered velocity profiles reported with the profile (A), (B) and (C), used in the data inversion; dashed black lines mark the intersection with the DFS trace. We show velocity error bars of 1 mmy -1 . All the maps are geo- referenced in UTM WGS84, Zone 40 N. 95 GNGTS 2013 S ESSIONE 1.1
