A view of the plume rising above Halema‘uma‘u

A wide view of the lava lake in Halema‘uma‘u taken during a helicopter overflight on the morning of November 9, 2021. Lava is once again visible in the spillway of the west vent after a brief drop in activity on Monday, November 8. The dark linear feature in the foreground (near center) is a remnant of the April 30, 1982 fissure, which partially collapsed into Halema‘uma‘u during the 2018 summit collapse events. The Southwest Rift Zone of Mauna Loa is visible in the background. USGS photo by L. Gallant.
