Episode 36 of the ongoing Halemaʻumaʻu eruption on Kīlauea ended abruptly at 4:16 p.m. on Sunday, after just under 5 hours of continuous fountaining.

The north vent stopped erupting at approximately 3:38 p.m. The south vent dropped from 1,000 to 500 feet around 3:48 p.m. It held stead for a little while before slowly declining and eventually stopping erupting at approximately 4:16 p.m.

Lava fountains reached a maximum of 1,000 to 1,100 feet during this episode. It produced an estimated 10 to 11 million cubic yards of lava.



The combined average eruption rate was over 650 cubic yards per second from the dual fountains, which is the highest effusion rate recorded during this eruption. Lava flows from the fountains covered about 60 to 80% of the floor of Halemaʻumaʻu crater on the Big Island.

Volcanic gas emissions have greatly decreased. Lava flows from this episode on the floor of Halemaʻumaʻu within the southern part of Kaluapele (Kīlauea caldera) may continue to exhibit slow movement or incandescence as they cool and solidify over the coming days.
