Fuego volcano (Guatemala): increasing explosive activity, ash plumes up to 2 km high

Nov 23, 2011 - The Guatemalan geophysical survey SERNAGEOMIN reports increasing explosive activity from Fuego volcano, one of the country's most active volcanoes. Fuego was observed producing ash clouds reaching 1500-2000 m above the summit crater (at ca. 3600 m altitude) which drifted SW and reached up to 20 km distance where they produced some ash fall, reported in the communities of Panimaché, Morelia, Sangre de Cristo, and Santa Sofía.

The explosions were accompanied by moderate to strong booming noises and shock waves that could be felt in up to 15 km distance. Near-constant rock avalanches are observed on the upper slopes beneath the summit crater, some of which reach the vegetated areas.
