Lava fountaining at Halema‘uma‘u west vent
On October 18, 2021, lava fountaining at the western vent in Halema‘uma‘u was generally a few meters (10 feet) high. However, frequent larger bursts—like the one in this photo—threw lava up to the height of the cone around the vent (approximately 25 meters, or 80 feet, high).
