The western vent (lower right) remains the dominant source of fountaining, while low lava fountains are still emerging through the southern portion of the lava lake (center right) (image: HVO)
The effusive eruption of the volcano continues within the Halemaʻumaʻu crater.
The activity is mainly focused at the western fissure where vigorous lava spattering has been building a horseshoe-shaped spatter cone around the vent. Low lava fountains continue to erupt from the chain of vents stretching from the lake’s center to its southern margin.
The lava lake crust develops a complex pattern as it flows away from its source at the western vent.
Sulfur dioxide (SO2) emissions remain elevated at approx. 7000 tonnes/day measured yesterday.
