Halema‘uma‘u Lave Lake—October 15, 2021

The eruption within Halema‘uma‘u continues. Lava fountaining from the western vent (center) feeds a rising lava lake. Activity has decreased over the past week and much of the eastern half of the lake surface (seen here in the foreground) has cooled and formed a solid crust. Lava from the active western lake surface occasionally flows over this crust on the north and south sides of the lake. USGS photo taken on October 15 by B. Carr.
