Tremor has dropped sharply, but at the moment of updating, strombolian explosions, ash emission and the effusion of the lava flow continue at reduced level.

Fuego (Guatemala): An increase in activity was indicated by the volcano observatory today. The explosions (strombolian type) at the summit vent occur now at rates of 6-8 per hour and lava effusion increased. Currently, the lava flow is headed towards the Cenize canyon on the SW side. It is a possibility that this activity continues to build up towards another paroxysm, in which case the occurrence of pyroclastic flows (mainly by collapsing lava flow fronts) is a likely and dangerous scenario.
Puyehue-Cordón Caulle (Central Chile and Argentina): A significant ash(?) plume was spotted on Terra's satellite images yesterday afternoon. Since there are no other reports suggesting that a (larger in this case) eruption has occurred (e.g. heat signals, eyewitness reports, webcam), it seems likely that the plume was from wind-mobilized ash from the 2011-12 eruption.
If new evidence of an eruption becomes available, we'll follow up, and please post a comment if you have other data.
A passenger on a cruise ship reported: "Cruise ship Seabourn Quest sailing out of Castro, Chile, just passed what we believe is the actively erupting Chaiten volcano. Eruption ash cloud clearly visible throughout sunset, 8.15 to 9.00pm, 12/14/2013. Pyroclastic cloud going down left (north) flank. Secondary vents erupting on the flanks."
Barren Island (Indian Ocean): New and relatively strong thermal signals are visible on satellite data. They suggest renewed (or increased) activity, perhaps in the form of lava flows.
