Tracking Changes in Yellowstone's Restless Volcanic System

Release Date:

Satellite-based surveying techniques (InSAR) allow scientists to view changes to the ground surface at Yellowstone. For more information see the Tracking Changes in Yellowstone's Restless Volcanic System fact sheet.

Over the past ten years scientists have been applying new satellite-based surveying techniques to monitor changes in the land surface elevation within Yellowstone Caldera. These new measurements add to monitoring data collected over the past 25 years and help increase our understanding of the slow up and down ground movements of the Yellowstone caldera above the subterranean magma and hydrothermal systems.
