Volcano

Guatemala
On 3 September 2026, the National Institute of Seismology, Volcanology, Meteorology and Hydrology (INSIVUMEH) and the National Coordinator for Disaster Reduction (CONRED) of Guatemala reported that the Fuego volcano maintained high levels of eruptive activity, with up to nine explosions per hour and ash columns reaching more than 4,500 meters above sea level. The activity represents a continuation of the eruptive cycle that began on 4 August 2026, which prompted an institutional Red Alert and the preventive evacuation of approximately 1,700 people, including 659 people registered in shelters from eight rural communities. Ashfall has continued to affect communities downwind of the volcano. Additionally, authorities continue to monitor drainage ravines (barrancas) due to the risk of lahars triggered by seasonal rainfall, while civil protection authorities maintain active alert measures.
