Update: Mt Kizimen
On Dec 23rd, unknown time, it erupted with a small 5km high ash/steam plume that traveled about 30km out from the mountain. There have been no changes in alert notifications since then, so can only assume this small ash/steam eruption is still ongoing.
Established Member
Additional Details available now, two small additional gas/steam eruptions on on Dec 24th and 27th

Updates:
Mt Kizimen - Still exhibiting some gas/ash and steam emissions, and the lava flows continue to effusce.
Mt Gorely - Siesmic activity increased last week to very high levels. Gas/Steam emmisions have become moderate to very strong. While it reamins at Condition Yellow, it is under an elavated watch condition due to it's proximity to a small town.

Updates:
Mt. Sheveluch - Had another ash eruption in the 16km height range.
Mt Kizimen - Still exhibiting some gas/ash and steam emissions, and the lava flows continue to effusce.
Mt Gorely - While it's still in Condition Yellow status, KVERT/AVO is now indicating possible ash eruptions in the 19km height range (About a VEI 2 scale eruption).

Updates:
Mt. Karymsky - Slightly heightened activity, including some small steam/ash venting.
Mt Gorely - Condition Yellow status, KVERT/AVO is still indicating possible ash eruptions in the 19km height range (About a VEI 2 scale eruption). Strong levels of Gas/Steam venting still ongoing.

Updates:
Mt. Karymsky - Still a bit more active, including some small steam/ash venting.
Mt Gorely - Condition Yellow status. Seismic data stream was lost on Feb 5th, and has not been re-established. KVERT/AVO is still indicating potential for ash eruptions in the 19km height range (About a VEI 2 scale eruption). Strong levels of Gas/Steam venting still ongoing and visable.
All things considered, I'll go out on a limb here now and say Mt. Gorley has a 90% probibility of an eruption within this next year. Hopefully if it does go it will be small, as its very close to a city (Gorley)

Updates: Mt Gorely - Condition Yellow status. Seismic data stream has not been restored yet. KVERT/AVO is still indicating potential for ash eruptions in the 19km height range (About a VEI 2 scale eruption).

Updates:
Mt. Karymsky - Changed to Condition Orange - Small ash erption on Fed 21st, less then a VEI-1 strength.
Mt Gorely - Condition Yellow status. Seismic data stream has not been restored yet. KVERT/AVO is still indicating potential for ash eruptions in the 19km height range (About a VEI 2 scale eruption). Strong levels of Gas/Steam venting still ongoing and visable. 1 year eruption probility 90%.
Without the seismic readouts at Gorely, it will be diffucult to determine if activity is increasing towards and eruption, or decreasing towards sleep.

Mt. Karymsky - Still Condition Orange - Periodic explosive activity has been continuing.
Mt Gorely - Condition Yellow status. Seismic data stream has not been restored yet. KVERT/AVO is still indicating potential for ash eruptions in the 19km height range (About a VEI 2 scale eruption). Gas/Steam venting still ongoing and visable, but at moderate levels this week. 1 year eruption probility 90%.

Mt. Sheveluch - Had another ash eruption, small this time in the 6,000 foot height range.
Mt. Bezmianny - Downgraded to Condition Yellow yesterday.
Mt. Gorely - Rumor mill this week indicates a possiblility that a small team of KVERT Vulcanologists are on their way to Gorley to repair it's Seismograph.
Established Member
Mt. Gorely - Rumor mill was incorrect, seismographs still offline at Gorely.
Established Member
Mt Kizimen - Was downgraded to COndition Yellow. Acitivity is reducing.
Established Member
Mt. Gorely - Activity has reduced back to moderate levels, seismographs still offline at Gorely.
Mt. Sheveluch - Explosive, Effusive, eruption in progess, VEI-3 level. Pending condition red status upgrade
No changes at the other three volcanoes.

Mt. Sheveluch - Condition Orange still, (borderline Condition red)
Full excerpt from KVERT announcements:
SHEVELUCH VOLCANO (1000-27)
56°38'N, 161°19'E; Elevation 3,283 m, the dome elevation ~8,200 ft (~2,500 m)
AVIATION COLOR CODE IS ORANGE
Explosive-extrusive-effusive eruption of the volcano continues. Ash explosions up to 32,800 ft (10 km) ASL could occur at any time. Ongoing activity could affect international and low-flying aircraft.
Explosive activity of the volcano continued: seismic data and visual observation showed ash plumes rose up to 32,800 ft and 16,400 ft (10.0 km and 5.0 km) a.s.l. on May 05 and 06-08, respectively. According to visual and satellite data, a viscous lava flow continues to effuse into the explosive crater of 2010 eruption, an incandescent of the lava dome and strong and moderate fumarolic activity accompanies the lava flow effusion. Ash plumes extended for about 500 mi (800 km) to the south-east of the volcano on May 05. Ash cloud was observed in 95 km to the south-east of the volcano on May 07. A thermal anomaly over the lava dome was noted on May 03-05 and 08-10.

Mt. Sheveluch still erupting with VEI 2 to 4 strenghts. There was a nice VEI 2 eruption on the 2nd, and can view a few images of it here. http://www.kscnet.ru/ivs/kvert/curre...name=Sheveluch

New image from Gorely, from last may. Some associated information at Kvert posted along with this image, indicates that the gasses coming out of the fumeral here at the time of the photo, is colorless and at a tempurature of 600c (1100f).

Alaid upgraded to Condition Yellow - Activity at this volcano is increasing, with thermal hot spots on satellite images indicated.
Klyuchevskoy upgraded to Condition Yellow today - Weak seismic activity with low level Strombolian activity.
Sheveluch still Condition Orange - Effusive Eruption continutes
Karymsky still Condition Orange - Modereate eruptions and seismic activity continues
Bezymianny still Contition Yellow
Kizimen still Contition Yellow
Gorley still Contition Yellow - Seismic activity has fallen back to moderate levels

Plosky Tolbachik Volcano upgraded to condition yellow today, after a series of seismic event last few weeks, cumulating in 250 shallow quakes yesterday, and then followed by a large, and still on going, volcanic tremor. Magma is definitely moving under this mountain.

The Day after I posted the notice on Plosky Tolbachik (Nov 28th) it erupted in an effusive lava euprtion (strombolian) from a fissure on the north flank. Condition was change to Orange. On the 29th, Condition was changed to RED as another effusive fissure opened on the sothern flank, and the nothern flack fissue intesfied with a serious flow.
Yesterday, the Southern lava flow completly burried KVERT's Natural Volcano Visitors Center as well as the siemograph stations near by.
Condition is back to Orange, but this appears to be a volcano that went from quiet to active in just under 3 weeks. So it can likely rapidly evolve at any time.

And it's under 3 weeks to 12/21/2012... hmmm.
Just kidding. Good job on the prediction.

Effusive eruption continues.

Nice, but what is that in the foreground; is that a dog?Originally Posted by dgavin

It's a large golden squirrel, known to frequent lava fields.

SQUIRREL!

It's russia's version of a golden retriver, can't rememeber the breed name right now.
Reports coming in today from KVERT that the volcanic tremors have incresed in force and at a magnitude of 7 mcm/s. If this measurment is in million cubit meters per seconds as I think, then this volcano may surpass the icelandic fissure eruption a few years ago in sheer magma flow rates. Also news coming in the another fumeral has opened up, this time inside the caldera, instead of on the flanks. IT will likely be another lava vent in a matter of days.

Plosky Tolbachik volcanic tremors have decreased since yesterday and at a magnitude of 4 mcm/s. Nasa has some satellite images available from Dec 1 pass showing the lava flows as there were then. http://earthobservatory.nasa.gov/IOTD/view.php?id=79898

Wow, those are great pictures

Plosky Tolbachik volcanic tremors back up to a magnitude of 6 mcm/s today.
A more recent photo form the 8th, at the south fissue. http://geoportal.kscnet.ru/volcanoes/imgs/1650.jpg
No additional news on the new furmeral in the central caldera yet.

Some really stunning photo's of Plosky Tolbachik from a Russian wildlife photographer.
