• HVO reports increased earthquake activity beneath Halemaʻumaʻu, first notable summit unrest since December 2024

    ByTeo Blašković

    A series of three small earthquake swarms occurred beneath Halemaʻumaʻu crater at the summit of Kīlauea Volcano, Hawaii, between January 13 and 14, 2026, marking the most notable shallow seismic unrest since the eruption’s onset in December 2024. The U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO) reports all events were below magnitude 2 and located 1.5–4 km (0.9–2.5 miles) beneath the surface. The activity follows the high fountain eruption of episode 40 on January 12, which produced 5.5 million m³ (7.2 million yd³) of lava within less than 10 hours.

    Kīlauea entered eruptive episode 39 at 20:10 HST on December 23, 2025 (06:10 UTC on December 24) as lava fountains rose from twin vents on the floor of Halemaʻumaʻu crater. Within about 95 minutes, fountain heights increased from 10 m (30 feet) to more than 420 m (1 400 feet), with lava flows covering 10–20% of the crater floor by 21:14 HST and a plume reaching 6 000 m (20 000 feet).

  • USGS V3 camera destroyed by lava fountain during Kīlauea’s Episode 38, Hawaiʻi

    A powerful lava fountain from Kīlauea’s Halemaʻumaʻu crater, Hawaiʻi, destroyed the USGS Hawaiian Volcano Observatory’s V3 streaming camera at around 10:00 HST (20:00 UTC) on December 6, 2025. The camera was recording live when an inclined fountain from the south vent buried it in hot pumice and tephra during Episode 38 of the ongoing summit eruption.

  • Episode 38 at Kīlauea produces extremely rare triple-fountain event and destroys USGS camera, Hawaiʻi

    Kīlauea’s Halemaʻumaʻu crater, Hawaiʻi, began erupting at 08:45 HST (18:45 UTC) on December 6, 2025, when fountains emerged from the north vent, marking the start of Episode 38 of the ongoing summit eruption. Within minutes, a south vent opened, and by 09:15 HST a rare triple-vent lava fountain was active, producing jets up to 370 m (1 200 ft) high and a 6 km (20 000 feet) plume above the summit. The eruption lasted 12.1 hours, covered more than half of Halemaʻumaʻu crater with new lava, destroyed the USGS V3 streaming camera, and ended abruptly at 20:52 HST on the same day (06:52 UTC on December 7).

  • New eruptive episode at Kīlauea produces strong lava fountaining and high sulfur dioxide emissions

    ByTeo Blašković

    Episode 37 of the ongoing Kīlauea eruption began at 14:30 HST on November 25, 2025 (00:30 UTC, November 26), producing sustained lava fountains about 120 m (400 feet) high from the north vent inside Halemaʻumaʻu crater. The eruption remains confined within Hawaiʻi Volcanoes National Park, with no impacts beyond the summit area. Seismic tremor intensified at the onset, and sulfur dioxide (SO2) emissions rose to around 50 000 tonnes per day, generating volcanic gas plumes and vog drifting southwest under light northeast winds.

  • Record-high effusion rate measured during episode 36 of Kīlauea’s Halemaʻumaʻu eruption

    Episode 36 of the ongoing Halemaʻumaʻu eruption at Kīlauea volcano, Hawaiʻi, ended at 16:16 LT on November 9 (02:16 UTC, November 10), 2025, after just under 5 hours of continuous fountaining. The event produced record-high lava effusion rates of around 500 m³/s (650 yd³/s) and built fountains up to 330 m (1 100 feet) high, covering 60–80% of the Halemaʻumaʻu crater floor.

  • Record lava fountains reach 460 m (1 500 feet) during episode 35 of Kīlauea summit eruption, Hawai‘i

    Episode 35 of the ongoing Halemaʻumaʻu eruption at Kīlauea volcano began at 20:05 HST on October 17, 2025 (06:05 UTC on October 18), producing simultaneous fountains from the north and south vents that reached record heights of approximately 460 m (1 500 feet). The eruption cloud rose above 6 000 m (20 000 feet) while lava flows remained contained within the crater.

  • Dual lava fountains from Kīlauea’s Halemaʻumaʻu crater reach 400 m (1 300 feet), Hawaii

    ByTeo Blašković

    Episode 34 of the ongoing Kīlauea eruption ended at 07:03 HST (17:03 UTC) on October 1, 2025, after 6 hours of lava fountaining from two vents in Halemaʻumaʻu crater at the volcano’s summit, Hawaii. Lava fountains reached up to 400 m (1 300 feet), erupting about 9 million m³ of lava at a peak effusion rate of 500 yd³/s. The eruption filled much of the western crater floor before activity ceased.

  • Lava fountains over 150 m (500 feet) in new eruption at Kilauea, Hawaii

    ByTeo Blašković

    A new eruptive episode started at Kīlauea’s Halemaʻumaʻu crater at 13:11 UTC (03:11 HST) on September 19, 2025, producing lava fountains over 150 m (500 feet) and a volcanic plume up to 3 000 m (10 000 feet) high. The eruption remains confined to the summit caldera within Hawaiʻi Volcanoes National Park.
