Puyehue-Cordon Caulle volcano (Chile) - Smithsonian / USGS Weekly Volcanic Activity Report for 15 January-21 January 2014 (Continuing Activity)
Based on analyses of satellite images, the Buenos Aires VAAC reported that on 16 January steam-and-gas emissions with minor amounts of ash rose from the Cordón Caulle rift zone, part of the Puyehue-Cordón Caulle volcanic complex, to an altitude of 2.4 km (8,000 ft) a.s.l. The plume quickly dissipated. The Alert Level remained at Green (lowest on a four-color scale).

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
