The eruption is occurring within the summit caldera of Kīlauea and started with small spatter fountains around 2:57 p.m., followed by lava flows beginning just two minutes later. Currently small dome fountains are reaching heights of 16 to 33 feet (5 to 10 meters), feeding a short lava flow from the north vent. No activity has been observed at the south vent. Earlier in the day, there were brief periods of weak, intermittent spatter, but sustained lava effusion only began just before 3 p.m. Seismic tremor at the site increased at the same time as the lava flow began. Kilauea eruption paused, but likely to begin again The tiltmeter at Uēkahuna continues to show inflation beneath Halemaʻumaʻu, the volcano’s summit crater, though it is expected to shift to deflation as the eruption progresses. Each eruptive episode since late December has lasted between 14 hours and 8 days, with pauses in between that have ranged from less than a day to nearly two weeks. The ongoing eruption is currently within the boundaries of Hawai‘i Volcanoes National Park, and there have been no significant changes in the East Rift Zone or Southwest Rift Zone. The U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) is continuing to closely monitor the eruption and will provide updates as needed. The current Volcano Alert Level for Kīlauea remains at WATCH, and the Aviation Color Code is at ORANGE, indicating ongoing volcanic activity that may affect aviation.
