Two lava fountains from Kilauea's Halema'uma'u crater on 9 November (image: HVO live webcam)Another such vigorous effusive episode started at the volcano yesterday.The 36th lava fountaining episode is ongoing within the Halemaʻumaʻu xcrater floor. The eruption came at 4:16 PM HST on November 9, after just under five hours of continuous overflows.The north vent ceased erupting around 3:38 PM, while the south vent’s fountain height dropped from 1,000 to 500 feet (300–150 meters) by 3:48 PM, remaining steady for a short time before gradually declining and stopping at 4:16 PM HST—marking the end of the episode.During the episode, lava fountains reached peak heights of 1,000–1,100 feet (300–330 meters). The event lasted just over five hours and produced an estimated 10–11 million cubic yards (8–9 million cubic meters) of lava. The combined average effusion rate exceeded 650 cubic yards per second (500 cubic meters per second), the highest rate recorded so far in this eruption. Lava flows from the fountains covered roughly 60–80 percent of the Halemaʻumaʻu crater floor.
