Footwall releif measurements for faults in the Zomba Graben Malawi. Footwall relief was measured every 1 km along strike using stacked profiles of TanDEM-X topographic data that had been sampled every 100 m along strike. We measured the difference in elevation between the highest point on the footwall within 3 km of the fault surface trace, and the elevation of the fault itself. #1 - Longitude #2 - Latitude #3 - Footwall Relief (m) #4 - Uncertainty (m)
