effusive eruption



Activity: vulcanian

Height: 3,763m




As has been noted through reports daily bulletins, the Fuego volcano was increasingly active since 1 August, which generated at that time the beginning of a new phase of effusive eruption, accompanied by explosions forming moderate ash plumes 12 km long, west and south-west, with the deposit of fine ash on the villages of Santa Sofia, Panimache, Sangre de Cristo and Morelia.



This activity has also issued an incandescent source of 200 meters high, showing constant avalanches of blocks   on the slopes of the volcano, and lava flow into the Canyon Las Lajas, which reached 2 km long, with a potential in increase   .


This is an effusive eruption, but there is a possibility of an increased activity and even the generation of pyroclastic flows.






The INSIVUMEH recommends:
At CONRED, to implement the yellow warning phase state (2) and hold it for the activity of the Fuego volcano.
At civil aeronautics to take precautions for air traffic, because of the dispersion of ash over a distance of 12 km to the southwest and west. «
