Overview
- INSIVUMEH reported the eruption began on Monday, August 3, and intensified into a paroxysmal phase with 200–300 metre lava fountains, large ash columns and repeated pyroclastic density currents.
- CONRED declared a nationwide orange alert and ordered preventive evacuations of El Porvenir and Las Lajitas, moving about 50 families into shelters and urging residents to self-evacuate if at risk.
- Pyroclastic flows have descended multiple ravines — including Seca, Ceniza, Taniluyá and Las Lajas — traveling roughly 5–7 km toward the volcano base and representing the primary immediate hazard to nearby towns.
- Authorities closed National Route 14, suspended in-person classes in affected municipalities, advised aircraft to avoid ash between roughly 4,450–6,000 m and urged people to protect water, food and breathing with masks or damp cloths.
- Fuego is one of Guatemala’s most active volcanoes with a deadly 2018 history, so officials are keeping emergency operations and monitoring in place and telling residents to keep 72-hour emergency kits ready.
