Fuego volcano eruption with pyroclastic flows.
Activity Type: vulcanian
Body type: composite Stratovolcano
Geographical location: 14 ° 28’54 “N Latitude; 90 ° 52’54” W. Longitude
The Fuego volcano continues its eruptive activity, generating pyroclastic flows like “Boiling Over” (phenomenon caused by overheating of the magma, then leaving the crater quickly with abundant volcanic material and hot clouds). Seismic recording of FG3 station shows the descent of small pyroclastic flows circulating through the canyon of Las Lajas, causing avalanches on their way.
This type of eruption provides a lot of debris in the canyons, filling up, so they can overflow in areas where it already exists deposits from past eruptions.
Due to weather conditions, these materials can cause lahars at high temperatures and affect downstream channels, causing floods.
Ash falls on the southern flanks, Southwest and West of the volcanic complex, at a distance of 20 km is not excluded.
The ash in contact with drops of water form the mud, it is advisable not to leave the house and to remain attentive to this activity.
This is an eruptive phase of Fuego volcano that can continue in the coming hours, days or weeks, it is not appropriate to be in the canyons or near them.
Therefore, the INSIVUMEH recommends:
At the SE-CONRED:
Implementing vigilance deems necessary depending on the activity and to be aware of the behavior of the volcano, given the existing deposits of current material can generate large lahars in the ravines of Las Lajas and El Jute in the evening because of rainfall today.
At civil aviation:
It is recommended to take precautions with air traffic, the ash plume moves to the South, Southwest and West, a distance of 20 km, with the opportunity to move further in the hours.
