A destructive tornado struck Albufeira in Portugal at around 11:00 LT on Saturday, November 15, 2025, leaving one person dead and injuring over 20 people. The event severely affected the Albufeira Campsite and Eden Resort Hotel, where multiple structures collapsed and vehicles were overturned.
A mud-volcano eruption occurred in Pingtung County, Taiwan, on November 12, 2025, producing five vents that expelled mud and flames up to 2 m (6.5 feet) high. Village authorities created diversion channels to prevent mud from entering nearby farmland.
A shallow M5.3 earthquake struck near Paphos, Cyprus, at 16:23 LT (14:23 UTC) on November 12, 2025, producing a rare rapid aftershock cluster. More than 20 aftershocks were recorded within the first hours, including M3.9 and M4.3 events occurring five and ten minutes after the mainshock. By the morning of November 13, the total number of aftershocks had reached 50. The Geological Survey Department reported that the early activity rate and the presence of two closely spaced events were unusual for the region’s modern instrumental record.
Effusive eruption at Nyamuragira volcano, Democratic Republic of the Congo, continues at elevated levels. Sentinel-2 imagery from November 12, 2025, shows lava overflowing the northern rim of the caldera and extending about 6.5 km (4 miles) along the northwestern flank. On November 14, 2025, TROPOMI detected a high SO2 plume at approximately 15 km (49 200 feet) altitude, confirming intensified degassing linked to sustained magma supply.
A major long-duration solar flare measuring X4.0 erupted from Active Region 4274 at 08:30 UTC on November 14, 2025, producing a fast CME. The event started at 07:44 and ended at 08:40 UTC.
A strengthening low-pressure system offshore is forecast to spread heavy precipitation and mountain snow across the Sierra Nevada from Thursday, November 13 through November 15, 2025. Winter Weather Advisories are in effect for the Eastern Sierra Slopes, Greater Lake Tahoe Area and the West Slope Northern Sierra Nevada, with snow levels forecast to drop into November 14 and accumulations reaching 30–60 cm (12–18 inches) at the highest peaks.
Interior Mendocino and Lake counties are under a Flood Watch from late Wednesday, November 12, through Thursday morning, November 13, 2025, as 50–75 mm (2–3 inches) of rain is forecast within several hours. Marine Storm and Gale Warnings are also in effect offshore, where winds up to 95 km/h (60 mph) and seas up to 8 m (27 feet) are expected.
Coronal mass ejections produced by a long-duration X1.7 on November 9 and X1.2 on November 10 appear to have merged on their way to Earth and impacted our planet at 23:00 UTC on November 11, sparking G4 – Severe geomagnetic storming. Another CME, produced by a major X5.1 flare on November 11, is expected to impact Earth by the end of November 12, causing another round of severe geomagnetic storming. Aurora watchers have already reported impressive sightings as far south as Zacatecas, Mexico.
A period of renewed eruptive activity occurred at Planchón-Peteroa volcanic complex on the Chile–Argentina border between late October and early November 2025. Volcanic Ash Advisory Center (VAAC) Buenos Aires issued multiple warnings for continuous ash emissions reaching altitudes of up to 4 600 m (15 000 feet). Local monitoring networks reported persistent degassing and minor explosions. The volcanic alert level remains at Yellow.
A major X5.1 solar flare erupted from Active Region 4274 at 10:04 UTC on November 11, 2025, producing a large Earth-directed coronal mass ejection (CME). NOAA SWPC issued a geomagnetic storm watch predicting G4 – Severe or greater conditions for November 12, G3 – Strong for November 13, and G1 – Minor for November 14. On November 12 and 13, aurora may be visible as far south as Alabama and northern California.
