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.

Kīlauea Volcano summit eruption — thermal map GIF

ANIMATED GIF: This animated image file (GIF) includes a series of thermal maps—ranging from daily to several weeks apart—made from helicopter overflight thermal imagery of Halema‘uma‘u crater, Kīlauea summit.

Halema‘uma‘u eruption sequence Digital Elevation Models

HVO uses regular Kīlauea summit helicopter overflights of Halema‘uma‘u crater to create digital elevation models (DEMs) of the crater.

Lava Lake Depth March 4th

Data from a Kīlauea summit helicopter overflight on March 4th allowed for the calculation of the depth of the lava in Halema‘uma‘u crater.
