Uplift in the Yellowstone Caldera

This image of ground deformation was created using data from several satellite passes from 1996 through 2000. The image shows 125 mm of uplift centred within the northern end of Yellowstone caldera (black dotted line), about 10 km south of Norris. Each full spectrum of colour (from red to purple) represents about 28 mm of uplift. The uplift is approximately 35 km x 40 km in size.
