InSAR image of Yellowstone ground movement from Sept 2004 - Aug 2006.

Yellowstone ground movement map from Sept 2004 - Aug 2006....

Detailed Description

This interferogram provides a map view of ground movements at Yellowstone. Each color contour represents a line of equal uplift relative to the ENVISAT satellite between Sept. 2004 and Aug. 2006. The center of the uplift is an elliptical region stretching from the northeastern part of the Yellowstone Caldera (the dashed black line) to the southwest. This area of maximum uplift encompasses both Yellowstone's resurgent domes, features long known for similar movements. During this time period, the north-rim uplift anomaly subsided (bullseye in the upper left part of the interferogram). The yellow lines are roads. The yellow triangles are locations of GPS stations with continuous data. The light blue lake within the caldera is Yellowstone Lake. Thin black lines are mapped faults. Figure courtesy of C.
