Map of recent earthquakes under El Hierro (IGN)
Fuego yesterday morning (INSIVUMEH)
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.
Ash emission yesterday from Reventador
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:

Volcanic activity worldwide 6 Sep 2013: Ubinas, Sakurajima, Rabaul (Tavurvur), Pacaya, Fuego, Karyms...
Etna (Sicily, Italy): Since a few days ago, the New SE crater has been producing weak ash emissions occasionally. Whether this is the precursor to more vigorous activity and when this will occur, is difficult to say at the moment, but it is a sign that the volcano is waking up from the slumber it has been in during the past 4 months. ...

Sakurajima (Kyushu, Japan): (4 Sep) A moderately large vulcanian explosion occurred this morning, producing significant fallout of lapilli and small bombs in several kilometers distance. Cars parked at the Arimura Lava observatory observation point to the south of the volcano were damages and windshields broken, at a distance of about 4 km. There are no reports of injuries to people. ... Lees alle

Tolbachik (Kamchatka): Although believed to have more or less stopped a week ago, it seems that weak eruptive has continued and regained some strength again now. Weak tremor has reappeared and incandescence could be seen again at the active vent at Tolbachinsky Dol at night. Tourists could observe strombolian activity and effusion of lava into the tube system on 30 August. ... Lees alle
