• Kīlauea enters eruptive episode 39 exactly one year into ongoing summit eruption, with lava fountains rising over 420 m (1 400 feet)

    ByTeo Blašković

    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

    ByTeo Blašković

    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).

  • Ambae volcano erupting after months of quiet, Vanuatu

    ByTeo Blašković

    Low-level eruptive activity resumed at Ambae volcano (Manaro Voui) in Vanuatu, with intermittent ash emissions observed since December 1, 2025. Satellite imagery from Himawari-9 confirmed continuous low-level ash and gas plumes reaching up to 1.8 km (6 000 feet) above sea level, drifting northwest. The Wellington Volcanic Ash Advisory Centre (VAAC) issued its latest advisory on December 4, describing the eruption as continuous but confined within the volcano’s summit area.

  • Orange alert in effect for Puracé volcano after renewed eruptive activity, Colombia

    ByTeo Blašković

    Volcanic activity at Puracé, Colombia, intensified on November 30, 2025, prompting authorities to raise the alert level to Orange for the Los Coconucos volcanic chain in Cauca Department on December 1. Since then, continuous tremor, long-period seismicity, and sustained gas-and-ash emissions have been recorded, with columns exceeding 700 m (2 300 feet) above the summit (4 650 m / 15 260 a.s.l.) and occasional ashfall reported in nearby communities.

  • 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.

  • Hayli Gubbi volcano erupts for the first time in recorded history, Ethiopia

    ByTeo Blašković

    Hayli Gubbi volcano in Ethiopia erupted for the first time in at least 12 000 years on November 23, 2025, marking its first confirmed Holocene activity. The eruption generated a plume rising to about 14 km (46 000 feet) above sea level before drifting toward the Arabian Peninsula. Updated satellite data from IASI-C on November 24 detected a large SO2 plume between 5 km (16 400 feet) and 17 km (55 800 feet), with a centre-of-mass height near 16 km (52 500 feet) and a total mass loading of 58.4 kt.
