Yellowstone Supervolcano: Earthquake Swarm, New Map Shows Ground Deforma...







The map, by USGS geophysicist Chuck Wicks, shows movement around the caldera between 2015 and 2017 using radar images of Earth’s surface collected from orbiting satellites.

In this time, the ground around the Norris Geyser Basin rose by just under 3 inches, while there was a downdropping of the earth within the Yellowstone caldera. In the map, the rings of color show where the ground’s elevation has changed.
