• 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.

  • Media claims of Mount Rainier tremor proven false by USGS and PNSN

    ByTeo Blašković

    Contrary to recent media coverage suggesting Mount Rainier had entered an unprecedented tremor phase, the U.S. Geological Survey (USGS) confirmed that no volcanic tremor is occurring at the volcano. The abnormal seismic signal detected over several days in mid-November 2025 originated from ice buildup and communication interference at the STAR station on Rainier’s west flank. Monitoring data from the Pacific Northwest Seismic Network (PNSN) show no signs of volcanic unrest, and the Alert Level remains at Normal.

  • 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

    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.
