Volcanic Maps

The USGS Volcano Hazards Program enhances public safety and minimize social and economic disruption from volcanic unrest and eruption. We accomplish this by delivering effective forecasts, warnings, and information about volcano hazards based on scientific understanding of volcanic processes. Learn more by exploring USGS volcanic maps.

December 21, 2020—Kīlauea summit interferogram

This “interferogram” was created from satellite radar data acquired over Kīlauea Volcano on December 6 and 21 (at 6 PM HST each day). The colored fringes show ground deformation that occurred during that 15-day period. Each fringe is equivalent to about 1.55 cm (0.6 in) of ground deformation towards or away from the satellite.
