December 6, 2025—Video views of episode 38 in Halemaʻumaʻu crater, Kīlauea summit

Views of Kīlauea summit eruption lava fountaining episode 38 in Halema‘uma‘u crater on the Island of Hawai‘i. This eruptive episode began from the north vent at about 8:45 am HST this morning, December 6. Smaller fountains began from the south vent at 8:49 am HST and quickly grew to over 1000 feet (300 meters) high and inclined to the south, towards a closed area of Hawaiʻi Volcanoes National Park. The north vent stopped erupting at 11:50 a.m. In addition to the tephra, volcanic gas is being emitted, with sulfur dioxide emission rates likely exceeding 50,000 tonnes per day. The high effusion rate of this episode is also producing a very dramatic plume extending over 20,000 feet above sea level. Both the National Weather Service and Washington Volcanic Ash Advisory Center issued special advisories about this plume, and the Hawaii County Civil Defense Agency issued a message about the potential for fine glass particles in communities downwind.
