Fuego volcano: large lahar through Ash Canyon towards towards OsnunaSaturday Sep 29, 2012 10:08 AM | BY: T
A large lahar traveled through the Ash Canyon (Barranco Ceniza) towards the community of Osnuna on 27 Sep between 14.30-15:50. More than 55 m of rainfall during a single hour (2.2 inches) remobilized still hot pyroclastic flow deposits from the 13 Sep eruption in the canyon including large tree fragments and boulders more than 1.5 meters in diameter. The lahar, strongly smelling of sulfur, cut the dirt road between San Andrés Osuna and Siquinalá. It was the first of these dimensions, but INSIVUMEH warns that more are possible.

In its latest report, INSIVUMEH counted 18 eruptions during 27-28 Sep, out of which 10 were moderately sized and produced ash plume up to 1 km height, and fountains of incandescent material of up to 200 m height, which generated avalanches on the upper crater flanks. ...

The volcano continues to increase its activity slowly. Incandescent strombolian pulses were seen at night throwing bombs to 100-150 meters above the crater and some of the material generated weak to modest avalanches when falling back. Rumbling and degassing sounds were noted at intervals of 1-6 minutes. ...
