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…
Around 71 percent of wells in Myanmar’s Ayeyarwady Delta exceed World Health Organization (WHO) safe drinking water limits, placing up to 12 million people at risk of long-term arsenic exposure, a new study led by the University of Portsmouth finds. Travelers and residents relying on untreated well water may be exposed if they consume or use it for cooking.
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.
Indonesia’s Geological Agency raised the alert level for Semeru volcano to the highest (Level IV) following a major eruption on November 19, 2025, that produced an ash column up to 17.9 km (59 000 feet) above sea level. Authorities ordered evacuations of at least 300 residents from nearby villages and expanded exclusion zones up to 8 km (5 miles) from the crater and along the Besuk Kobokan valley. No casualties have been reported so far.
The Weather Prediction Center (WPC) has issued a Moderate Risk of Excessive Rainfall for south-central Texas through Thursday, November 20, 2025, with 75–125 mm (3–5 inches) of rain possible and locally higher totals. The same frontal system is forecast to advance eastward into eastern Oklahoma and the Ozarks by Thursday night, bringing a Slight Risk of excessive rainfall to those regions.
A major eruption took place at Semeru volcano, Indonesia, on November 19, 2025, producing large pyroclastic flow and ash column up to 16.5 km (54,000 feet) above sea level. The Aviation Color Code was raised to Red while authorities issued exclusion zones along Besuk Kobokan.
Ground-based observations on November 16 and 17, 2025 captured multiple jets on the interstellar object 3I/ATLAS, including sunward jets and an extended anti-tail. The images were obtained from telescopes in New Mexico, USA and France. A public online observation by the Virtual Telescope Project is scheduled at 04:15 UTC on November 19, 2025.
