Fuego volcano (Guatemala) activity update: weak to moderate explosions, lava flows
Saturday Sep 15, 2012 12:05 PM | BY: T
In the course of the night there were 7 explosions, 4 weak and 3 moderate expelling fine ash at 500 and 800 meters above the crater. The stronger explosions were accompanied by rumbling noises and created plumes that drifted 7 km to the west and SW where fine ash fall occurred in the Sangre Cristo area.
The Taniluya lava flow is reportedly now 1200 m long (although the special bulletin the evening before said 200 m), and the Ceniza flow 200 m long. Both are still active.

The Fuego volcano eruption has decreased to normal activity, INSIVUMEH reports last night. The seismic station FG3 shows signals typical for weak explosions that send fine ash clouds up to 500 meters above the crater. ... [more]
The eruption has started to decline from 10 am in the morning today 14 Sep, INSIVUMEH reports. ... [more]

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]
