  • Partial collapse at Mount Merapi sends lava down slopes, Indonesia

    ByTeo Blašković

    A partial collapse occurred at Mount Merapi volcano, Central Java Province, Indonesia, on November 10, 2025, producing lava flows on its slopes. The event follows continuous volcanic activity observed in recent days, including a pyroclastic flow that traveled about 1 500 m (4 921 feet) southwest at 15:19 LT (08:19 UTC) on November 9, lasting 188.32 seconds. The volcano remains at Alert Level III (Siaga), and residents are advised to follow official safety recommendations.

  • Heavy lake-effect snow creates whiteout conditions, disrupts travel south of Chicago

    ByTeo Blašković

    Powerful bands of lake-effect snow brought traffic on parts of Interstate 57 (I-57) south of Chicago, Illinois, to a standstill amid whiteout conditions on the morning of November 10, 2025. The National Weather Service (NWS) warned drivers to use extreme caution as snowfall rates exceeded 7 cm/h (3 in/h) in localized bands, producing near-zero visibility and hazardous travel across portions of northeastern Illinois.

  • Rio Bonito do Iguaçu tornado upgraded to EF-4, placing Brazil among sites of 2025’s most violent tornadoes worldwide

    ByTeo Blašković

    A new assessment by MetSul Meteorologia confirms that the deadly tornado that struck Rio Bonito do Iguaçu, Paraná, Brazil, on November 7, 2025, reached EF-4 intensity on the Enhanced Fujita Scale, with estimated wind speeds between 250 km/h and 300 km/h (155 mph to 186 mph). The event killed six people, injured more than 400, and destroyed much of the city’s urban area, making it one of the most intense tornadoes recorded globally in 2025.

    ByTeo Blašković

    A lava overflow started from Stromboli’s North Crater area at around 10:00 UTC (11:00 LT) on November 9, 2025, feeding a lava flow on the upper Sciara del Fuoco. The activity, observed by the National Institute of Geophysics and Volcanology (INGV) through surveillance cameras, was accompanied by modest but continuous spattering from at least two vents in the North Crater area.

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

    ByTeo Blašković

    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.

  • Earthquake swarm in progress along Calaveras fault near San Francisco, California

    ByTeo Blašković

    Over 40 earthquakes were recorded along the Calaveras fault southeast of San Ramon, California, between November 9 and 10, 2025. The largest event, M3.8, occurred at 09:38 LT (17:38 UTC) on November 9 at a depth of 9.2 km (5.7 miles). Geological and seismic studies show that the Calaveras fault is capable of generating an event in the M6.5 to M7.0 range over long-term timescales.
