The eruption of the volcano has undergone a change from explosive to mainly effusive over the past few hours, INSIVUMEH reports in the latest bulletin last night (22h00 local time). Instead of a large sustained ash column, there are now smaller pulsating ash emissions reaching 3-700 m height, but instead the volcano is producing large (for Fuego) lava flows between 900 and 1,000 meters long and 150 wide. The different activity is also leaving a different type of seismic signature and has remained stable over the past hours. ... [more]

Fuego volcano's activity further increased after 03:25 local time on 13 Sep, and culminated in violent explosive activity with medium-sizes pyroclastic flows running down its slopes (mainly through Ceniza Canyon), INSIVUMEH reports.

There has been an increase in volcanic activity. During 24 hours observation 11-12 Sep, there were 13 explosions, 11 weak and 2 moderate ones producing ash clouds reaching 400-600 m height and drifting 6 km to the W and NW. At night, strombolian activity with incandescent material was seen ejected to 75-100 m height. Weak avalanches traveled towards Taniluya and Ash canyons. ... [more]

INSIVUMEH observed 5 weak explosions ejecting ash plumes to 400 m above the crater, drifting west and northwest accompanied by rumbling and degassing sounds lasting between 1-5 minutes. ... [more]

4 weak explosions with ash plumes rising 300 m and some glowing material ejected to about 100 m were observed during the past observation period 8-9 Sep. Small avalanches of rocks towards the Tniluya and Ceniza Canyons were produced by material falling back from the explosions. Weak degassing sounds are heard. ... [more]
