a) Topographic map of the LAGF area generated from SRTM Global DEM. White dashed lines are locations of topographic profiles represented in Figure 5b. Normal faults, interpreted from field and topography observations, and unresolved lineaments from 1/60,000 scale structural lineament mapping are shown as black lines. Viewpoint location of Figure 6 is shown on the map. b) Topographic profiles extracted SRTM Global DEM. Normal fault location is pointed out on the profiles.
