West vent activity in Halema‘uma‘u

Telephoto image of the west vent in Halema'uma'u crater that is erupting low fountains and emitting a gas plume

Detailed Description

During a helicopter overflight of Halema‘uma‘u crater on November 9, HVO geologists observed spattering within the west vent cone and lava entering the lake via a spillway that is now tubed-over. Sulfur dioxide (SO2) emission rates remain elevated with the largest volcanic gas plume coming from the west vent. USGS photo by B. Carr.
