The effusive eruption of the volcano continues.
Vigorous lava fountains reached by lava jets surpassed 50 m-60 m (164 ft-197 ft) and produced amounts of pumice, Peleʻs hair and volcanic glass fragments downwind along the rim and beyond Halemaʻumaʻu crater.
Over the past several days, a thick layer (approximately 27 meters or 89 ft) of molten lava has accumulated as a lava lake at the base of the crater, partially drowning the vents resulting in subdued fountaining.
Sulfur dioxide (SO2) emissions decreased to a 12,000 t/d. Although the amount of gas and volcanic particle production has decreased since the eruption onset, they both remain significant local hazards within the plume.
However, the Hawaiian Volcano Observatory (HVO) lowered the alert level for the volcano to „orange“.
