Puyehue-Cordon Caulle volcano (Chile): possible eruption / ash plume reported
dim., 15 déc. 2013, 07:4307:43 AM | AUTEUR : T
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."

Puyehue-Cordon Caulle volcano (Chile) - Smithsonian / USGS Weekly Volcanic Activity Report for 11 December-17 December 2013 (New Activity / Unrest)
A scientist from NOAA's National Environmental Satellite, Data, and Information Service (NESDIS) reported that an ash cloud drifting NNE from the Cordón Caulle rift zone, part of the Puyehue-Cordón Caulle volcanic complex, was visible in satellite images starting at 0800 on 14 December. The scientist noted that, although it appeared to be a fresh emission, the cloud was likely re-suspended ash from strong southerly winds. In addition, no other evidence of renewed activity was detected. ... Read all

We reported a new eruption yesterday from Caulle volcano, but it soon turned out that the observed ash plume originated from very vigorous remobilization of ash deposits on the volcano. ... Read all
