Detailed Description

During a USGS Hawaiian Volcano Observatory monitoring overflight the morning of January 24, 2025, geologists observed that parts of the recently erupted lava flows are already showing signs of alteration. Fumarolic areas where degassing has occurred are marked by white alteration that has developed on the lava flows that make up the floor of Halema‘uma‘u. USGS photo by J. Barnett.
