Gorely volcano last week had a new vent open up on the wall of it's crater, but wihtout an increase in Siesmic activity. The vent opened up on the 17th of June and has been emitting gasses and steam with a temperature of 800-900 celcius.

KVert has upgraded the volcano from status Green to Yellow, and has since stated they expect it to erupt eventually.

KVERT has increased the likelyhood of a Mt. Gorley eruption in thier latest informational release. However they also said they are out of funding again, and will be forced to close down July 1st....so it's a bit uncertain about how up to date I'll be able to keep people on this volcano.

Bleh!

What, in vulcanology, is a griffon exactly?

Somewhere, sometime ago, I seem to remember a reference to bubbling water in a lake being referred to as a griffin/ beast and there is the Griffith theory of fractures, but in reality I got nuthin (sic).

So, I would like to know as well.

Looking at the picture (http://www.kscnet.ru/ivs/kvert/current/grl/280708GrlMlnkb.jpg), it is a lake with what looks like very localized bubbling so that's probably it.

No news from KVert on Gorley, but they did announce a sixth mountain in Kamchatkan has gone active. Mt. Ebeko at the southern edge has been emitting steam and small amounts of ash. 6 out of 10 of thier major volcanoes active, I'm not certain, but I think that might be a record for volcano activity in a single region.

I have several volcano books, including the text from my volcanology class, and none list that word in the index.

It may be a Russian specific use of the word грифонов (griffons) to designate such localized bubbling, then it got translated literally.


Do your books mention gryphon for a subtype/feature of mud volcanoes? That's mentioned on Wikipedia.

From the The Intellectual observer (http://books.google.com/books?id=Iso-AAAAYAAJ&pg=PA442&dq=%22By+Professor+Forbes+the+waters+were+examined +at+their+source+or+griffon+%22&hl=en&ei=GwExTN3FHML-8Aa44bjICw&sa=X&oi=book_result&ct=result&resnum=1&ved=0CCkQ6AEwAA#v=onepage&q=%22By%20Professor%20Forbes%20the%20waters%20were %20examined%20at%20their%20source%20or%20griffon%2 0%22&f=false), Volume 8 1866; GOOGLE Books pg 442

The following is a snipet:


years many careful observations have been made but no permanent variations have been brought to light The most recent series of observations with which we are acquainted is that by Dr Scoresby Jackson in August 1 863 described in vol xxiii part iii of the Transactions of the Royal Society of Edinburgh By Professor Forbes the waters were examined at their source or griffon as it is termed of the spring where the waters issue from the rock They are conducted thence by means of various channels to the different parts of the thermal establishments as douches baths etc and to the buvettes which are the public fountains where persons ordered for their health to drink the waters are supplied At this spot a thermometer placed for a few minutes under the constantly flowing stream records the temperature of the water at the buvettes but not by any means its temperature at the griffon which is often a considerable distance from the buvette As the rock is from time to time explored and the buildings are improved alterations at both sites are occasionally made The constancy of temperature at the buvette is however in general as remarkable as at the griffon of the spring itself In Dr Scoresby Jackson's experiments the temperatures were recorded at both places At whatever point


It seems that it is an archaic term.

So basically an archaic term for where the water comes out in a hot spring.

Updates on Gorley and Ebeko.

Local residents have reported explosions of gas/steam at Ebeko since july 2nd, although no large plumes have been detected ob satalite.

Yesterday 8th Mt. Gorley erupted with a gas/steam plume that was visible on satalite's and extended 30km to the south of the volcano.

dgavin
2010-Jul-16, 06:29 PM
Updates on Gorley and Ebeko.

Ebeko is still rumbling but satalite was obsured last week so no way to tell if there have been changes.

Gorley:

Harmonic Tremors now under way and increasing in frequency, currently at 1.8mkm/s. Gas and steam emmisions have increased in size, ranging upwards of 150km from the volcano on satalite images. Thermal anomoly at lake side has been increasing in size and temperature, while the level of the lake iteself has started decreasing. Probility of eruption is high.

Mt. Gorley /may/ have erupted today.

While there are no updates from AVO/Kvert on this yet, Satellite imagry today is showing a /non-reflective/ cloud (this means more ash then steam) starting at Gorely's location and extending upwards of 400 miles (640km) to the WSW.

Latest updates

Mt. Ebeko: Activity is subsiding and the volcano's status has been downgraded to condition green.

Mt. Gorely: Although still at condition yellow the activity is increasing. A strong non explosive gas/steam/some ash eruption did occur on July 20th and has continued. Average ground and lake temperature in the crater has increased form 29c to 46c over the last week. The level of the lake continues to fall and many new fumerols have formed as well. Eruption of Gorely is imminent!

Latest Update on Mt. Gorley.

Gas/Steam emission continues and has been basically going since July 20th. The volcanic (harmonic) tremor activity continues, though there is no update on if it's increased or not. The level of the lake is still falling, and the steam/gas vent area starting to show signs of sulfer and other mineral deposits. An eruption here is still very probable.

Thanks Mr. Gavin.

And for the rest of you for tracking down that gryphon refference. Good job!

Latest update on Gorely:

Gas/Steam emmisions continue uninterupted. Sciesmic activity (EQ swarms and Harmonic Tremors) are considered at a high level. The thermal readings from the crater are still present, but no new updates on the lake level due to lack of cloud free days for observations by KVERT. An eruption here is still considered very very likely.

Nice, not much more infor then KVERT was releasing though.

I'm just guessing here but from the imagry available it looks to be about a VEI 2 eruption. Not very explosive at all, but emitting a lot of ash and tephra.

dgavin
2010-Oct-27, 07:14 PM
Not much new information available on Mt. Klyuchevskoy yet. An unpublished status brief inidcated that both ground and satelite visual monitoring were obscruted yesterday.

I did some checking and the plume height qualifies it for a VEI catagory of 3. Status is still set to warning(active)/red levels. The webcam station about 5 km from mountain appears to still be broadcasting, but only black images. Assumtion is the lens is ash covered, possibly ash damaged.

dgavin
2010-Oct-27, 07:30 PM
According to Vulcanologist John Seach, the ash plume from 23rd eruption of Mt. Klyuchevskoy reached a height of over 30,000 feet and extended out-wards for over 300km.

This qualifies the eruption as a VEI 5 category (Plinian), basically something equivalent to the St. Helen's eruption of the 80's. So evidently this may be more of a significant eruption then it first appears.

dgavin
2010-Oct-27, 11:23 PM
Another explosive eruption at Mt. Klyuchevskoy just little while ago.

According to information received so far, the plume is already over 32,000ft (>10km) height, has pierced above the clouds, and being blow to the east (out into the pacific).

Roads from Mt. Klyuchevskoy to the town of Klyuchi have been closed, due to 0 visibility. Reports from Klyuchi indicate the town is in perpetual darkness, but no evacuations are reported as of yet.

Possible VEI 6 eruption underway. Will be able to gage it better as more information comes in.

Woah, major misread on my alerts.

This potential VEI 6 is not Mt. Klyuchevskoy but Mt. Sheveluch!

There are now two concurrent erruptions underway in the Kamchatkan region, Both around VEI 5 catagory, possibly this one rating a VEI 6.

*edit to add*

The web cam in town of Klyuchi is now completely black. Even street lights are not showing.

Mind you, the following is more in the nature of specualtion then facts. Climate changes due to Volcanic ash are not a well understood science.

The VEI catagories are similar to the Ricter Scale, in that they are a logirithmic scale.

http://vulcan.wr.usgs.gov/News/MSH2004/VEI_information.pdf
http://en.wikipedia.org/wiki/Volcanic_Explosivity_Index

VEI 5 eruptions might slightly alter climate in a hemiphere for about a week.
VEI 6 might have about a 1-3 month effect on climate.
VEI 7 from 3 months to 2 years.
VEI 8 2 or more years possible effects.

If (and thats still and if) Mt. Sheveluch pans out to a VEI 6 the two effects on the climate might be more atmopsheric condensation (more clouds due to water nuecleating on the ash) and a slight drop of temps from the ash and clouds blocking sunlight (by slight something in the order of maybe a 1/4 of a degreee C lower then normal.

Probably what we'll see from this (again if it's a VEI 6) is more of a cloudier, damper winter, then a cooler one. The effects would probably ony last a month or so, once the ash is rained out, things return to normal. Also the effects would be more pronounced closer to the volcano's then further away. Likely meaning that the western parts of North America contient will see a much damper then normal winter, and as ash moves east, less and less of an impact.

However until the actual size of the eruption can be determined, this again is nothing but specualtion on possible impacts of a VEI 6

Troubles coming in three? Hard to say, I managed to find some more facts. Source article is here (http://www.physorg.com/news/2010-10-russia-kamchatka-volcanoes-spew-giant.html) but its from an Associated Press source, so don't bank on these as solid facts. The Article does have a pic of the eruption column at Mt. Shiveluch however, so i recommend following to link to view that at least.

Summary of Article:

According to Associated Press, the Kamchatka ESM (Their version of FEMA) issued an alert today about the potential for an eruption at Mt. Gorely

Mt. Shiveluch eruption may be winding down already, max ash cloud heights were around 33,000feet. So sounds like solid VEI 4 eruption at this point, possibly a VEI 5

Mt. Klyuchevskaya eruption is on going and showing no signs of slowing down soon. The ongoing eruption here is about a VEI 2 levels, however it had another explosive episode about 3 hours after Shiveluch erupted yesterday, ash clouds also reaching 33,000feet. So another VEI 4/5 eruption.

No Flight restrictions have been issued by FAA or Tokyo Narita as of yet.

dgavin
2010-Oct-29, 07:09 PM
New KVERTreport out today.

Not much has changed from yesterday, the two eruptions are still ongoing. Ash clouds from both are extending out to the east about 1500miles, (2500km). They are definately looking more and more like VEI 4/5 eruptions. No reports of Lahar's or Pyroclastic flows from either one yet.

Mt. Klyuchevskaya has two effusive lava flows down the the west and south west flanks.

Mt. Shiveluch is still completely obscured from visual observations, so it's unknow at this point if had a directed blast eruption or not. Likely it didn't, but determination of that will need to wait for visual observations.

Mt. Gorley still seems to be unchanged (contrary to the AP article) other then the steam/gas emission increses that were noted before.

Status on both Mt. Klyuchevskaya and Mt. Shiveluch have been droped to Orange/watch. From the Kvert report sounds like that they are saying Mt. Shiveluch 's activity might be done, other then some minor ash eruptions. Mt. Klyuchevskaya's eruption is slowing down, but still has some effusive laval flows.

dgavin
2010-Nov-02, 07:04 PM
Mt. Klyuchevskaya ash plume height only 18,000 feet now (5.5 km). Lava flows on flanks appear to be slowing down.

Mt. Shiveluch no ash plume since late yesterday, still has an elevated level of siesmic activity however.

dgavin
2010-Nov-05, 07:30 PM
Kvert Report out today.

Mt. Klyuchevskaya, eruption may be done and sciesmic activity has sharply decreased since the 4th, but there is possibility for further activity still.

Mt. Sheveluch eruption continues, with ash clouds reacing 19,000 ft (5.8km) height. The initial eruption on Oct 27th, blew out about half of the existing lava dome (http://www.kscnet.ru/ivs/kvert/current/shv/index.html) (link goes to images at KVERT web site). It caused a Pyroclastic flow that extened out to 15km, and wiped out a small forested area.

With this new data, that pins this Mt. Sheveluch eruption down to a VEI 5, just barely. It was rougly speaking, about 1/3 the strength of the St. Helens eruption.

Kronotsky is beautiful.

ETA: in looking at that photo, I'm intrigued by the two rivers on either side of the volcano. Look how they seem to join right at the shoreline. It's almost as if they don't break through to the sea at all. I tried looking closer using Google Earth, but the view there was taken when the area was ice-bound.

Updates:


Mt. Kizimen - Down graded back to condition Orange on the 15th. Although the eruption continues, the ash cloud heights and output amount of the eruption, barely qualify it as a VEI 3.

My thoughts on it so far:

It's unknown if this will be the extent of it's activity, or if this is buildup to a more active phase. while the mountain does show a history of very explosive eruptions, in the vein of St. Helens, this doesn't appear to be leading to one of them. The possible lava flows on the dome are still on going, and now appear as 'Very Bright' to the IR satalite's that monitor the volcano.

This seems to inidicate that it's likely more of a building phase type of activity, then a destructive one, which may be behind it being take off the Red list.

Mt. Bezmianny - Downgraded back to Condition Orange:

From KVERT : Duration of seismic event of the eruption was 40 minutes. Ash fall was noted at Krasny
Yar (45 km to the NNW from the volcano). Width of ash deposits was 35
km. No activity was observed on satellite images probably due to bad
weather conditions. Meteorological clouds were around 8 km ASL so ash
clouds could be lower.

*Edit to Add*

SHEVELUCH VOLCANO (1000-27)
5638'N, 16119'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.

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.

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.

Plosky Tolbachik tremors are up to 17 mcm/s now, the lava from the southern fissue have become very fluid, and the lava flow from it now extends out to 20km distance from the mountain. Additionaly 2, possibly more, new cider cones have been identified around the southern fissue.

Another image from KVERT http://geoportal.kscnet.ru/volcanoes/imgs/1660.jpg

Volcanic tremors have increased to 26 mcm/s today. I'm not certain as I still can't nail down this mcm/s measurement Russia is using, but if it's magma flow rate bases, I think this volcano is now top of the charts for magma flow.

It's impactiing KVERT's ability to monitor nearby Mt. Bezymianny siesmographs last few days, in that they can only identify events at Mt. Bezymianny if they are over magnitude 2.5 As this relates to the 17 mcm/s rate, that likely means that today, the harmonic tremors expressed in Magnitude of quakes, is like about equivlent of a 2.7 earth quake, that doesn't stop.

Thats...a fairly intense amount of continuous shaking.

2012-Dec-19, 09:04 PM
Based on everything i've been reading and watching, I'm going to make a few predictions based on flow rates. We'll see if I learned my lessons or not based on actuall outcomes. The rather rapid increace in the tremor magnitudes, seems to indicate it might have the potential for a caldera collapse.

So here are my best guesses:

If Plosky Tolbachik passes 35 mcm/s flow, then 15% chance it will have a caldera collapse event, around VEI 5 strength
If Plosky Tolbachik passes 42 mcm/s flow, then 35% chance it will have a caldera collapse event, around VEI 6 strength
If Plosky Tolbachik passes 50 mcm/s flow, then 50% chance it will have a caldera collapse event, around VEI 7 strength (Crater Lake type event)
If Plosky Tolbachik passes 75 mcm/s flow, then 80% chance it will have a caldera collapse event, from VEI 7 to VEI 8 (Newberry Caldera type event)
If Plosky Tolbachik passes 150 mcm/s flow, then 99% chance it will have a caldera collapse event, VEI 8 (Long Valley Caldera to Yellowstone Caldera, type super volcano)

And just to pander to those worried about a certain date in two days, my silly version:

If Plosky Tolbachik passes 2000 mcm/s flow, then 100% chance for a never before recorded, VEI 9 (Decan Traps, ELE type event)

I seriosuly doubt a volcanos flow rate could increase from 26mcm/s to 2000mcm/s in a mere two days though, so I wouldn't worry about a VEI 9. It would take over 10 days of it's currect rate of increase to reach that sort of magnitude. I'll actualy be surprised if it hit my 35 mcm/s mark on my first prediction even in a months time.

There isn't a history of caldera collappses in that region, so while it might get close, I think the mountian will actually sort of blow itself out (not up) before it gets to even 35 mcm/s where it might have a flow rate potential for a caldera collapse.

dgavin
2012-Dec-20, 07:58 PM

This is a good one, all along the reports of Tolbachik mention a giant thermal signature. Here is an ifared sat image taken on Dec 12th, thats been released, of it finnaly.

Mt. Tolbachik back up to 5.9 mcm/s on tremors, still unable to find updated news on the extent of it's lava flows, though I've seen estimates thats it out to 25km now.

Mt. Kizimen after a year of inactivity, and being bumped down to condition Green last week, erupted with a lava flow today. It's back at condition orange.

No changes in Mt. Snow's condition.

New image of Tolbachik and what is beign called 'The Cone'. They still havent named the new cinder cone yet, so it may just become, 'The Cone'. Tremors at 3.93 mcm/s today.

Tolbachik's Tremors back up to 6.1 mcm/s. Again not much else to report from sources yet.

Mt. Tolbachik: The fifth new cinder cone is still growing rapidly, still no name for it yet, officaly. Still finding information on the the extent of the lava flows is scare, but some sources still indicate 20-25km, with some Nasa sat photos showing the furthest reaches of the flows now covered with snow, meaning those have cooled.

Mt. Kizimen: Lava flows and incadesence on the summit, she's definately going active again

Mt. Sheveluch: A number of hot rock avalanches this week, most of the ash from it was from these avalanches.

Mt. Karymsky: Still erupting with moderate explosions of ash and tephra, more akin to how volcanos behave in the continental US.

Mt. Gorely: Siemicity has decreased to moderate levels, seems to be setteling into a steam/gas/fumeral stage. Looks like my predictions on this one were off base. The large fumeral tube is still incadescent.

Mt. Klyuchevskoy: No significant changes in activity.

Mt. Bezymianny: Siesmicity readings still being overpowered by activity at near by Tolbachik, still have a minor effusive lava flow on going.

Mt. Alaid: Activity is steadly decreasing, may not erupt.

Mt. Snow: Still obscurred, still no photographic confirmation on earlier reported minor lava flow.

Mt. Tolbachik: Has started exibiting explosive as well as effusive eruptions, and the lava flows on the western side have become very fluid again. 4 new cinder cones reported around Krasny Cone. (9 total now)

Mt. Kizimen: Lava flows at the summit, and hot avalances.

That's a cool video. At first, I just blithely clicked your link without taking in how you titled it (360-degree video) and watched two minutes of a helicopter overflying some volcanoes. Only after reading the article did I realize you are meant to rotate the view with your mouse. Much better that way. :)

Tolbachik still going strong, with the four new cinder cones growing rapidly. Lava flows are beign report as being highly fluid again.

This is an intresting trait, in that it's Lava seems to vary form less to more fluid without a discernable pattern, other then it seems to correlate with the low and high mcm/s measurments.

Tolbachik still doing it's thing, and the four new cinder cones are still growing. The largest is about 1/3 the size of Krasny cone now. If eruption contues at the current rate, in about over four months it will surpass Krasny cone in size. If it goes on for over eight months, then Krasny cone will be assimilated into this cone. I'm curious if the eruption will go on long enough to see that.

Interesting, after the swarm of quakes on one side of Kamchatkan, some very strong and very deep quakes happened directly opposite on the other side. I'm wondering if we might be looking at a slab break off event here. Where part of a subducted slab slowly tears off partly or fully from the rest of the slab.

Mt Klyuchevskoy spent five hours this morning at Condition Red then was downgraded back to Condition Orange.

Per VKERT
Activity of the volcano a little decreased but continue to be high. Ash plumes raise up to 26,200 ft (8 km) a.s.l. and extende to the east-north-east of the volcano. Phreatic explosions at the south-western flanks of Klyuchevskoy volcano continue. Lava flows effuse on the south-western, western and south-eastern volcanic flanks.

Explosive-effusive eruption of the volcano continues. Ash explosions up to 32,800 ft (10 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft.

Hawaii would be the most active volcano, in a singular context, but Kamchatka alone has the distinction of being the most active volcanic by region, with the Aleutians coming in second. That is excluding the mid ocean ridges (but includes Iceland)

Interesting, I didn't know that.

Mt. Zhupanovsky had a explosive steam/rock/ash Eruption on the 23rd-25th of Oct, but it's already been downgraded back to condition Green.

The Ash cloud was minimal, and it was never raised past condition Yellow. This is a remote mountain, and details on this were not available until the 27th.

Mt. Klyuchevskoy was down graded to condition Yellow today. It's stil in an eruption cycle, but at this point it's being termed as a Strong Fumeralic Eruption.

Yes, thats the same mountain, Klyuchevskaya Sopka, Klyuchevskoy, or Kliuchevskoi. I tent to use the names as they appear on the Russian KVERT web site, which is Klyuchevskoy.

Nice Blog Post by Phil!

Mt. Gorley has been removed from the VONA since January, I have found no information statement, but did find an month old Russian news article with image, showing that the fumeral seems to have stopped, but what remains of the crater lake, had been classified as dangerously acidic.
