Guatemala: Increased volcanic activity at Fuego Volcano as of July 10 /update 1

Event

Officials have reported ongoing volcanic activity at Fuego Volcano as of July 10. Scientists have recorded two to five explosions an hour, gas emissions every one to five minutes, and ash dispersed up to 15 km (9 miles) to the west and southwest. Lava ejections are producing moderate-to-strong avalanches towards the Ceniza chute, and lava flows have been observed at the summit. Authorities have not yet called for any evacuations.

Researchers warn that lava flows are possible in the coming days. Residents are advised to avoid the Panimache I and II drainage areas, Morelia, Santa Sofia, Yucales, Palo Verde, El Porvenir, La Rochela, Guadalupe, and El Zapote. Guatemalan civil protection authorities are on alert and in communication with nearby community leaders; police and relief workers have also been on standby.

An eruption could cause localized transport disruptions; flight delays are possible at La Aurora International Airport (GUA) in Guatemala City if there is a significant ash plume. Ground transport disruptions could also occur. Falling ash could cause slick driving conditions on nearby roads and reduced visibility, leading to localized traffic disruptions.

The Fuego Volcano is located at the juncture of Chimaltenango, Escuintla, and Sacatepequez departments, approximately 40 km (25 miles) west-southwest of Guatemala City.

Context

Fuego Volcano is Guatemala's most active volcano. Eruptions on July 4 included lava flows of more than 1 km (0.6 miles) towards the Ceniza chute, extensive degassing, pyroclastic explosions reaching more than 8 km (5 miles) away), and ash emissions. An eruption in March 2022 prompted the evacuation of 400 people, though there were no reports of fatalities. An eruption on June 3, 2018, left 431 people dead or missing.

Advice

Heed the advice of local authorities and obey restrictions around the volcano. If larger eruptions occur, confirm flight schedules, especially at GUA. Drive cautiously, as roads may be slippery from volcanic ash. If operating in areas affected by an ash cloud, consider remaining indoors when possible. Individuals who must be outdoors should use face masks and observe other precautions to avoid ash inhalation. Volcanic ash and gases can cause eye irritation and respiratory problems. Do not rub irritated eyes; flush them with water. Seek medical attention if you have trouble breathing.
