Chirpoi (Kurile Islands, Russia): SVERT reported that a thermal anomaly from Snow, a volcano of Chirpoi, was detected in satellite images during 13-15 November. The Aviation Color Code remained at Yellow.

Chirinkotan (Northern Kuriles): SVERT reported that during 13-15 November a thermal anomaly over Chirinkotan was observed, as well as steam-and-gas emissions during 14-15 November.

Sakurajima (Kyushu, Japan): The past days have been relatively calm at the volcano with only infrequent and smaller explosions and less ash emission, compared to the intense phase of activity during 13-15 November.

Langila (New Britain, Papua New Guinea): An SO2 plume from the volcano is visible on satellite data today, indicating continuing activity.

Sinabung (Sumatra, Indonesia): Since the large vulcanian eruption on Wednesday (9 km ash plume), several smaller explosions occurred. Ash plumes rose to estimated 12,000 ft (3,6 km).

Colima (Western Mexico): The current eruptive phase continues. Local newspapers reported explosions every 30-35 minutes, with plumes up to 2 km high. Lava flows (and incandescent avalanches) descend on the flanks of the volcano.

Popocatépetl (Central Mexico): No significant changes in activity have occurred. CENAPRED reports occasional weak emissions mostly of steam and sometimes with small amounts of ash. Significant degassing and SO2 emissions continue.

Santa María / Santiaguito (Guatemala): A phreatomagmatic (water-magma interaction driven) explosion yesterday morning produced a plume of fine ash rising to 3.2 km altitude (700 m above the lava dome) and drifted SE, causing ash fall in Finca La Florida.

Fuego (Guatemala): A surge in activity occurred yesterday, with drastically increased numbers of strombolian explosions and lava effusions. The explosions generated ash plumes rising about 500 m and caused moderate ash falls in areas to the south and SW, mainly in the village of Sangre de Cristo.
Today, the volcano seems to have calmed down again.
This was the 4th (and so far weakest) paroxysmal phase of the volcano this year.

Chaitén (Southern Chile and Argentina): Increased seismic activity has been detected under the volcano, Chilean scientists reported.
The devastating Plinian eruption of Chaitén in May 2008 forced the evacuation of the entire population of the small coastal town of Chaitén, located only a few kilometers south of the volcano. After the initial explosive phase, several lava domes have been growing slowly by extrusion of degassed, viscous magma. This phase ended in 2011 and since then, the volcano has only produced degassing.
