Bezymianny volcano on the Kamchatka peninsula is reported by KVERT to have erupted at 21:45 UTC on 16 December:

According to seismic data, an explosive eruption of the volcano began at 21: 45 UTC on December 16. Ash explosions > 10.0 km (>32,800 ft)ASL could occur at any time. The activity of the volcano could affect international and low-flying aircraft.

Seismic activity of the volcano began to increase from December 08, but a size of thermal anomaly – from December 16. At 17:07 UTC on December 16, a size of the thermal anomaly was 6 pixels and the temperature was +19.4 with -23 of background. No visual and video data – the volcano obscured by clouds. But possibly ash fall began occur at Kozyrevsk village from 22:25 UTC on December 16

Tokyo VAAC issued an ash advisory at 22:51 UTC reporting ash at FL320 (32,000 feet or 9750 metres). No further information as yet, and as the KVERT bulletin indicates the Bezymianny webcam is currently showing only a blank cloudy sky.

UPDATE. A further ash advisory from Tokyo, issued 23:41 UTC, reports ash up to FL350 (35,000 feet or 10,600 metres).

According to seismic data, an explosive eruption of the volcano began at 21: 45 UTC on December 16 and continues at present. Probably ash plumes rose > 10.0 km (>32,800 ft) ASL. The activity of the volcano could affect international and low-flying aircraft.

Seismic activity of the volcano continues. No visual and video data because the volcano obscured by clouds. According to data by AMC Yelizovo, ash plumes can extend to the west and north-west from the volcano. Strong ash fall occurred at Kozyrevsk village from 22:20 till 23:30 UTC on December 16 but a thickness of ash deposits was ~2 mm. Weak ash fall occur at Kozyrevsk at present time. According to satellite data (NOAA-18, 4m5, 00:56 UTC, December 17), an ash plume extended about 170 km (105 mi) to the north- from the volcano.

the sub-actual plume is visible on the MODIS website, on the 00h00 TU shot. Beautiful! It’s a very dense, but quite clear, plume.
