Figure Caption. This is a "Phase Unwrapped" image produced by interferometric processing of the radar scene. This image can be thought of as contour map of topography along the northern coast of Chile. This image combined with a dozen or so ground control points will provide a good digital elevation model. An earthquake occured in this image near the lower central portion and after "Double Differencing", the topographic change related to the seismicity will become evident.
