Kīlauea summit, Hawaii, is showing strong gas pistoning and overflows ahead of the next eruptive episode, with Pele’s hair and volcanic gas already affecting the summit area and nearby communities. The Hawaiian Volcano Observatory (HVO) warns that episode 33 lava fountaining is expected to begin over the next 1 to 3 days.
Episode 23 of the Halemaʻumaʻu eruption at Kīlauea volcano, Hawaiʻi, began at 16:15 HST on May 25, 2025, with lava fountains exceeding 300 m (1 000 feet) from the north vent.
Lava fountains reached 215 m (700 feet) at Kilauea volcano on Tuesday, April 1, 2025, during episode 16 of the ongoing Halemaʻumaʻu eruption.
Episode 13 of Kīlauea’s ongoing eruption at Halema’uma’u crater ended at 01:13 UTC on March 12, 2025, after 12 hours and 37 minutes of lava fountaining. Lava covered over 60% of the summit floor, and sulfur dioxide (SO2) emissions peaked at 40 000 tonnes per day.
Episode 12 of the ongoing Halema’uma’u eruption began at 07:30 LT (17:30 UTC) on Tuesday, March 4, 2025, with sporadic lava flows from the north and south vents. Continuous fountaining reached heights of 150–165 m (490–540 feet) by 00:20 UTC on March 5 and is expected to increase further. The eruption is part of the ongoing activity that started on December 23, 2024. The USGS maintains the Volcano Alert Level at Watch and the Aviation Color Code at Orange.
Episode 9 of the ongoing Halemaʻumaʻu eruption began at 10:16 LT (20:16 UTC) on February 11, 2025, producing lava fountains up to 100 m (330 feet) high. The eruption is part of the activity that started on December 23, 2024. The USGS maintains the Volcano Alert Level at Watch and the Aviation Color Code at Orange.
Volcanologists reporting in Oxford’s Academic Journal of Petrology have confirmed that the Kīlauea and Mauna Loa volcanoes share a deep magma source within the Hawaiian plume.
A period of increased seismic activity was detected at the Kama’ehuakanaloa Seamount on January 21, 2025. While the exact cause remains undetermined, the seismic activity may be linked to magma movement beneath the volcano.
The eruption at Kilauea volcano’s summit resumed at 09:15 LT (19:15 UTC) on January 15, 2025, with lava flowing from the 2 north vents at Halema’uma’u summit. It marks the fourth eruptive episode since December 23, 2024.
Volcanic activity at Kilauea transitioned to a more vigorous phase at 04:00 UTC on December 29, 2024, with lava fountains rising 20 to 30 m (60 to 100 feet) high and covering 20% of the Halema’uma’u floor.
