Etna (Sicily, Italy): No significant change in activity has occurred during the past days. Degassing from the New SE crater has decreased again, probably because the magma column has dropped again, and tremor is currently low.

Mild strombolian explosions seem to continue from Voragine, as suggested by small puffs of ash visible. Strong degassing and perhaps dilute ash emissions are also originating from the NE crater where deep-seated explosive activity occurs and can be heard when on its rim.
Karymsky (Kamchatka): Tokyo VAAC reported an ash plume at 12,000 ft (3.6 km) altitude extending east from the volcano this morning. Occasionally, the volcano has stronger than average strombolian to vulcanian-type explosions.
It is one of the few volcanoes in the world that have been in more or less constant eruption for several centuries.
Rinjani (Lombok): The eruption continues with no significant change. When observed yesterday on location, the Barujari cone was in violent strombolian activity and the lava flow was still weakly alimented, creating a small steam plume at the lake entry of the flow.
Impressively, the lake temperature has risen so much that large parts of the surface are steaming. The volcanic activity has been producing only smaller ash plumes during the past days, which did no longer affect air traffic to / from Lombok and Rinjani.
Dukono (Halmahera): Near constant ash emissions continue from the volcano. An ash plume at 8,000 ft (2.4 km) altitude extended 40 km SW this morning (Darwin VAAC).
Colima (Western Mexico): Explosions of small to moderate size continue to occur from time to time. The more violent and ash-rich ones produce eruption lightning as the one attached, taken by our friend Hernando on 15 Nov 2015.
Tungurahua (Ecuador): The activity of the volcano has increased during the past days. Near-continuous explosive eruptions at the summit crater have been creating ash plumes that rose up to 3 km and drifted into westerly directions. Up to 2 mm of fresh ash fall occurred in areas up to 10-20 km west of the volcano. Incandescent bombs were seen ejected during the explosions as well.
The ash falls already started to cause significant damage to infrastructure (roads, buildings) and farmland. In particular, fields in the village of Choglontus located only 6 km southwest of the summit have almost completely been destroyed by the ash.
Piton de la Fournaise (La Réunion): The alert level of the volcano was lowered today as no more eruptive activity occurred since the last phase of the latest eruption ended more than two weeks ago.
Most trails inside the Enclos are now again open for public, with the exception of the wide area of and around the still hot pahoehoe lava flow field emplaced at the western foot of Dolomieu crater during the recent eruption.
(A significant, potential lethal hazard is breaking through the fragile crust of the shelly pahoehoe lava, potentially falling into still very hot hollow spaces underneath).

Karangetang (Siau Island, Sangihe Islands, Indonesia): (15 Nov) Activity at the volcano has decreased a bit, judging from the overall thermal signal, but continues with slow lava extrusion and small explosions at the summit crater, generating incandescent avalanches. ... read all
