Volcano Discovery Sept 7. 2013
Etna (Sicily, Italy): Last night, very deep-seated strombolian activity could be observed from both the Bocca Nuova and the New SE crater. This indicates that (similarly to early this year) magma has risen into the upper parts of the conduits beneath both vents. It might only be a question of time until this activity increases (perhaps even towards new paroxysms) and maybe becomes focused on one of the two craters.
El Hierro (Canary Islands, Spain): (6 Sep) Earthquake activity remains elevated, although most quakes are extremely small and not felt. The area of the hypocenters is about 10 km below the central part of the island.
Fuego (Guatemala): The volcano observatory reports an increase in seismic and explosive activity occurred yesterday. There were frequent moderate to strong explosions, generating shock waves that could be heard and felt in up to 12 km distance.
Ash plumes rose up to 1 km from the summit and moved in westerly directions for about 10 km distances. Constant glowing avalanches were observed on the upper southern flank towards the Ceniza canyon.
Reventador (Ecuador): While the other notoriously active Ecuadorian volcano, Tungurahua, has been very calm recently, eruptive activity from Reventador has increased again. Ash emissions and explosions occur more frequently and have gained in strength again, following a phase of less intense activity.
At least one of the recent explosions generated a pyroclastic flow on 5 Sep on the south side of the volcano. The following time-lapse video shows explosive activity yesterday seen from the webcam, during a phase of (rare) relatively clear weather.
