Normal faults in rifting environments create scarps with 10s to 100s of meters of relief, with strikes perpendicular to the spreading direction. Medium scale digital topography, with elevation spacing of 30-100 m, captures these features and allows extraction of the fault scarp orientations and relief. Digital elevation models like SRTM and ASTER GDEM cover the entire land surface at this scale, and significant underwater bathymetry exists, especially over mid-ocean ridges. Statistical techniques can identify fault scarps in these environments.
