Volcanic ash emissions from Fuego volcano observed at 4 300 m (14 000 feet) a.s.l., Guatemala

Volcanic ash from Fuego in Guatemala was observed at 4 300 m (14 000 feet) above sea level at 07:00 UTC on March 28, 2026. The advisory was issued by the Washington VAAC at 07:26 UTC.

The ash cloud was reported at an altitude between the surface and FL140, equivalent to 4 300 m (14 000 feet) above sea level. Volcanic ash was not detected in satellite imagery due to weather clouds in the summit area, but emissions were visible on the webcam. No Aviation Color Code was stated in this advisory.

According to the Smithsonian / USGS Weekly Volcanic Activity Report, eruptive activity at Fuego continued during the week of March 11-18, 2026, with daily Strombolian explosions producing gas-and-ash plumes that rose up to 1.2 km above the summit and drifting as far as 30 km (19 miles). Ashfall was reported in villages located downwind from the volcano during this period.

Fuego is a stratovolcano in southern Guatemala, characterized by frequent small to moderate explosive eruptions producing ash plumes, pyroclastic flows, and lava flows. Hazards include ashfall, pyroclastic flows, and lava flows, which can threaten nearby communities such as San Pedro Yepocapa, San Juan Alotenango, and Antigua Guatemala. The volcano is closely monitored due to its persistent activity and proximity to populated areas.
