The volcanic unrest at Turrialba seems to intensify, and signs of a possible new eruption in the near to medium future are getting stronger: According to OVSICORI-UNA a gas-and-steam plume from Turrialba rose to an altitude greater than 5.3 km (17,400 ft) a.s.l. on 5 December. Fieldwork confirmed an unusual output of gas from several fumaroles along the S outer wall. Areas burned by acute acidification have extended in the last month. Pastures turned yellowish near the upper areas, and native and exotic tree species were impacted as well as birch tree patches along most drainages. Within the W crater, temperatures of fumaroles reached 280 degrees Celsius and native sulfur was present. Read all- More about Turrialba volcano

Anak Krakatau continues its new strombolian activity from the new vent south of the summit crater. The eruptions are producing small ash plumes, ejections of incandescent spatter bombs as well as lava flows, as news reports and data from KRAKMON indicate. Seismicity was at elevated levels. - More about Krakatau volcano

KVERT reported a viscous lava flow erupted from the summit crater of Bezymianny volcano on 9 November. During an overflight on the same day, 4-km-long pyroclastic flow deposits from 5 November were observed on the SE flank. Lava flow-front collapses from older lava flows on the SE flank were also evident. A strong thermal anomaly is present on satellite data.

CVGHM lowered the Alert Status of Kelut on 8 November from 4 to 3 (on a scale of 1-4), due to a decrease in seismicity and deformation. Temperatures of the crater lake were measured at 75 deg C on 6 Nov, and 150-210 deg C on the surface of the new lava dome. According to a local news article, a volcanologist reported that the lava dome was 250 m in diameter and 120 m above the crater lake surface. On 11 November, a plume rose to an altitude of 3.7 km (12,000 ft) a.s.l. and ashfall was reported in several areas.CVGHM recommended that evacuees could return to their homes, but should stay clear of the mountain within a 3-km radius was restricted.

VAAC reported that ash plumes from Ubinas rose to altitudes of 5.5-8.5
km (18,000-28,000 ft) a.s.l. and drifted NW and NE during 23-27
October.

During 24-30 October the lava dome at SoufrièreHills changed very little. Seismic activity was very low and low-level rockfall and pyroclastic flow activity continued.
During 25-26 October, vigorous lahar activity was noted, especially to the E, including the Tar River valley. Ashfall was visible over N Montserrat, possibly due to rockfall activity and steam venting.
On 30 October a small pyroclastic flow was observed in the Tar River valley. The Alert Level remained elevated at 4.

KVERT reported that seismic activity at Shiveluch was above backgroundlevels during 19-26 October. Based on seismic interpretation, ash
plumes rose to an altitude of 6.9 km (22,600 ft) a.s.l. and small hot
avalanches occurred. Observations of video footage indicated that
gas-and-steam plumes rose to altitudes of 3.3 km (10,800 ft) a.s.l. on
21 and 25 October. Based on observations of satellite imagery, ash
plumes drifted SE on 19 October and a thermal anomaly was present in
the crater every day during the reporting period. The Level of Concern
Color Code remained at Orange.

flow. Observations on 26 October confirmed that a tube-fed pahoehoe flow along the N margin of the main channel advanced 2.4 km from the channel end. A few
small earthquakes were located beneath Halema'uma'u crater, and along
the lower SW rift zone and S flank faults during the reporting period.
