Fuego volcano (Guatemala) activity update: strombolian activity, glowing avalanches, ash plumes 500-800 m high
Thursday Apr 05, 2012 12:05 PM | BY: T
INSIVUMEH reported that during 31 March-1 April and 3-4 April explosions from Fuego produced ash plumes that rose 500-800 m above the crater and drifted 10 km W and NW.
During the night lava fountains rose 100-150 m above the crater and formed avalanches that traveled towards the Río Cenizas drainage. Based on analysis of satellite imagery, the Washington VAAC reported that on 1 April an ash plume drifted 13 km WSW and a well-defined thermal anomaly was observed.

INSIVUMEH reported that during 1-2 March explosions from Fuego produced ash plumes that rose 600 m above the crater and drifted 15 km W and SW. Ashfall was reported in Yepocapa (W), Sangre de Cristo (W), and Panimache II (SW). Some explosions produced rumbling and degassing sounds. A 300-m-long lava flow descended the SW flank and produced block avalanches that reached vegetated areas. On 4 March the number of explosions increased to about 4-5 per hour. Explosions generated ash plumes that rose 600 m above the crater and drifted 12 km SSW. Rumbling sounds were heard 7 km away. ... [more]

The effusion rate of the lava flow from the summit crater of Fuego seems to have increased in recent days. The flow is now reaching a length of 350 m, according to the latest reports of INSIVUMEH. Summit crater explosions (Strombolian style) are low to moderate in intensity. [more]

A slight increase at Fuego volcano has been observed in the past days. Occasional strombolian explosions are producing light gray ash columns between 200-500 m height above the crater, accompanied by rumblings. The explosions eject incandescent material to about 100 m. The bombs fall back in the area of the crater rim and cause weak avalanches. ... [more]
A white steam plume reaching 150 m in height is present all the time, dispersed to the west and southwest of the volcano. Occasional strombolian explosions producing light gray ash columns between 200-500 m height above the crater, accompanied by rumblings and ejecting incandescent material to about 100 m, which falls back in the area of the crater rim and causes weak avalanches. ...

Weak ash explosions continue at Fuego volcano. INSIVUMEH reported for 13 February that 9 eruptions were counted, producing plumes up to 500 m high and occasional rumbling noises. A steam plume is rising constantly about 100 m from the crater. The ash drifted 8 miles WSW. ... [more]
