Halema‘uma‘u west vent—November 23, 2021

Detailed Description

Lava erupts through a perched lava pond in the active western vent of Halema‘uma‘u crater, and supplies lava to the lava lake. Spatter bursts like the one seen here disrupt the pond surface nearly continuously and occasionally throw lava outside the vent, building up the cone. This burst is approximately 5 meters (16 feet) tall. USGS photo taken by B. Carr on November 23, 2021.
