Interferogram shows range change at Mauna Loa and Kīlauea

Color interferogram showing ground deformation

Detailed Description

Data from the European Space Agency (ESA) Sentinel-1A and Sentinel-1B satellites on March 31, 2019, and January 31, 2020, produced this interferogram. Each fringe, or band of colors, represents 2.83 cm (1.1 inches) of range change—the distance between the satellite and the ground. Counting fringes gives the total range change between two satellite passes.
