This USGS video was taken during a helicopter overflight at approximately 10:30 a.m. Thursday, Jan. 7, 2021. It shows the ongoing eruption within Halema‘uma‘u crater.
Video is shown at 3-times normal speed.
Hawaiian Volcano Observatory geologists noted that the dome fountain, which had been persistent near the base of the west vent area, had subsided and was no longer present. Lava continues to enter the lake at the base of the west vents. Visual and thermal imagery collected during the overflight are used to map the ongoing activity.
