The Hawaiian Volcano Observatory (HVO) reports that „episode 30 vigorous fountaining of the ongoing Halemaʻumaʻu eruption began at approximately 1:20 a.m. HST on august 6 and is currently producing broad fountains150-300 feet (45-90 meters) high from the north vent.
Lava flows from the north vent have covered about 20% of the floor of Halemaʻumaʻu crater. There is a line of small fountains that formed south of the old south vent area that are producing lower volume flows. This appears to be a new vent for this eruption and seems to be associated with a cluster of small earthquakes just south of Halemaʻumaʻu.
Past episodes have produced incandescent lava fountains over 1000 feet (300 meters) high that produce eruptive plumes up to 20,000 feet (6000 meters) above ground level. According to the National Weather Service, winds are light and variable from the north direction, which suggests that volcanic gas emissions and volcanic material may be distributed to the south but may fall in a broader pattern than during typical trade winds.“
