A strong and shallow earthquake registered by the USGS as M6.6 struck near Sinabang, Indonesia, at 04:56 UTC on November 27, 2025. The agency is reporting a depth of 25.4 km (15.8 miles). EMSC is reporting the same magnitude and depth. According to the Indian Ocean Tsunami Warning and Mitigation System (IOTWMS), there is a potential tsunami threat to countries bordering the Indian Ocean.
A powerful hailstorm hit Erechim, Rio Grande do Sul, Brazil, on November 23, 2025, producing hailstones up to 10 cm (3.9 inches) in diameter and injuring over 150 people. Authorities declared a state of emergency after damage extended across hundreds of homes and dozens of schools.
A powerful explosive eruption took place at Bezymianny volcano in Kamchatka, Russia, on November 26, 2025, with ash reaching 11.4 km (37 400 feet) a.s.l., as of 04:00 UTC. The Aviation Color Code was raised to Red due to ongoing explosions that could affect regional and international flights.
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.
China launched the uncrewed Shenzhou-22 spacecraft at 04:11 UTC on November 25, 2025, to restore a safe return option for the three-member Tiangong space station crew, after debris damage earlier in the month rendered their original Shenzhou-20 return module unusable. The previous crew returned using the Shenzhou-21 arrival vehicle, leaving the current crew without an evacuation craft until Shenzhou-22’s launch. The astronauts remain in stable condition as docking procedures proceed.
Ash and sulfur dioxide released by Ethiopia’s Hayli Gubbi volcano, erupting for the first time in at least 12 000 years, disrupted regional air travel between November 24 and 25, 2025. The eruption produced a high-altitude plume reaching about 14 km (46 000 feet) above sea level, spreading eastward across the Arabian Peninsula and India, where aviation authorities issued advisories, rerouted long-haul flights, and temporarily suspended operations on affected routes.
Severe mid-November flooding across central Vietnam has left 102 people dead or missing as of November 24, 2025, with Đắk Lắk suffering the worst losses and widespread destruction reported to homes, agriculture, and transport infrastructure.
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.
Tropical cyclone activity and heavy rainfall affected northern and central Vietnam from October through mid-November 2025, triggering flooding and landslides that killed at least 300 people and affected around 189 000. Vietnam activated the Union Civil Protection Mechanism on November 13 to request emergency assistance, while rainfall totals of up to 500 mm (20 inches) were forecast through November 20, maintaining high risks of renewed flooding and landslides.
A major eruption at Mount Semeru, East Java, Indonesia, on November 19, 2025, produced large pyroclastic flows descending the southern slopes. One of them was captured on video, allowing both the sight and sound of the approaching flow to be recorded. The video shows a large pyroclastic density current moving downslope at high speed, generating…
