Figure 18. IFSAR-based terrain motion map showing land subsidence in Las Vegas, Nevada over a nearly four-year period. (a) IFSAR-based terrain motion map. Subsidence is significant primarily in the outlined regions, with the subsidence being greatest in the darker region in the upper left quadrant.
