We're hearing all kinds of reasons for the cold snap and severe weather globally, with the result that the global-warming thesis is being raked over the coals, so to speak. But is anyone discussing the Icelandic volcanic eruption of last year as the cause? It seems as if most of the world has forgotten the eruptions of Eyjafjallajökull, "which, although relatively small for volcanic eruptions, caused enormous disruption to air travel across western and northern Europe over an initial period of six days in April 2010."

If history is an example, it is quite possible that this season's arctic freeze in the Northern Hemisphere, as well as other weather patterns such as the cyclone in Australia, are results mainly of this recent volcanic event on Iceland. Indeed, this phenomenon is common enough to have a name, "volcanic winter."

Kizimen eruption continues: threat to wild reindeer
The continuing eruption of the Kizimen Volcano in Kamchatka poses a threat to wild reindeer which are listed as endangered species.

As the volcano continues to spew ash for hundreds of kilometers, reindeer are leaving their traditional habitat for lack of fodder.

Reindeer moss, the animals’ only food in winter, is buried under a thick crust of ice and ash.

Experts from the Krontosky Nature Reserve warn that Kamchatka’s less than 1,000 reindeer may die out as a result of the eruption.

Kizimen, one of the 29 acting volcanoes in Kamchatka, has been spewing ash since December 2010.

More ash in Kamchatka
The Shiveluch volcano has spewed a new plume of ash 7.5 km above the Kamchatka Peninsula in Russia's Far East. The ash cloud sprawled 143 km to the northwest.

According to ITAR-TASS report on Monday, the authorities had announced the orange alert level warning aircraft about volcanic dust and gases in the air. At present, there is no risk to human health.

Shiveluch is one of Kamchatka's largest volcanoes. It rises more than 3,200 meters above the sea level.

Volcano in Russia's Far East spew ash to 6,000 meters

VLADIVOSTOK, May 3 (Xinhua) -- The Shiveluch volcano on the Kamchatka peninsula in Russia's Far East, has spewed ash to an altitude of 6,000 meters above sea level, local media reported Tuesday.

The seismic activity at the volcano intensified at 4:30 local time Tuesday (1730 GMT Monday) and reached its peak at 6 a.m. to 8 a.m. local time (1900 to 2100 GMT Monday) before gradually abating, the RIA Novosti news agency reported.

Though experts said there was no danger for local communities, an aviation "orange" alert has been assigned to the area.

Meanwhile, Kizimen, another volcano on the peninsula, has become active and spewed ash into the air of up to 7,000 meters.

Kamchatka volcano continues ash spewing
An active volcano on Russia's Kamchatka Peninsula is currently spewing plumes of ash at a height of up to 9 kilometers (5.6 miles), Russian scientists reported on Tuesday. Scientists have registered two strong eruptions in the last 24 hours. The 3,283-meter (10,771-foot) Shiveluch volcano increased activity in May 2009 and periodically spews ash from three to eight kilometers. Clouds of volcanic ash could pose threat to air traffic because the tiny particles can cause problems with aircraft engine turbines. There are more than 150 volcanoes on Kamchatka, and 29 of them are active.

Large explosive eruption is likely at Russian volcano
One of Russia’s largest and most active volcanoes erupted Friday sending ash more than 10,000 feet into the air. Officials said a much larger eruption is “likely”.

Shiveluch (also spelled Sheveluch) is one of the largest and most active volcanoes on Russia’s Kamchatka Peninsula. It has been spewing ash and steam intermittently—with occasional dome collapses, pyroclastic flows, and lava flows, as well—for the past decade.

Shiveluch has had over 60 large explosive eruptions during the past 10,000 years. Catastrophic eruptions took place in 1854 and 1956, when a large part of the lava dome collapsed and created a devastating debris avalanche. The last significant eruption ocured in late May 2011 resulting in ash being sent to a height of 7.5 kilometres above sea level. The ejection was accompanied by an earthquake at the volcano that lasted more than 10 minutes.

According to Kvert, which monitors Kamchatkan and Northern Kuriles Volcanic Activity: “Explosive-extrusive 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. Moderate seismic activity of the volcano continues. According to seismic data, ash plumes rose up to 32,800 ft (10.0 km) ASL on June 15. According to visual data, moderate gas-steam activity of the volcano was observing on June 10 and 12; clouds obscured the volcano on the other days of week. According to satellite data, a gas-steam plume containing small amount of ash extended about 16 mi (26 km) to the north-west from the volcano on June 10. A thermal anomaly was registered over the lava dome on June 10 and 12-13; clouds obscured the volcano on the other days.”

The Kamchatka Peninsula, located along the Pacific “ring of fire,” includes more than 100 volcanoes. While most of these volcanoes are not actively erupting, many are considered dangerous due to their eruptive history and their proximity to population centres and air travel corridors.

Kamchatka volcano belches out ash to 10 km above sealevel

Petropavlovsk-Kamchatsky, Jun 21 (Itar-Tass) One of the major volcanoes in the Kamchatka Peninsula, the Shiveluch, has belched out ash to the elevation of 10 kilometers above sea level, sources at the Kamchatka affiliation of the Geophysical Service of the Russian Academy of Sciences said today. A total of two series of local seismic events lasting from 40 minutes to 60 minutes have been registered at the volcano. According to seismic surveyors, they might have been accompanied by the exuding of ash to the elevations of 6.7 kilometers and 10 kilometers respectively. The ash columns could not be observed visually since the summit of the volcano is overcast with clouds. There has been no fallout of volcanic ash in the nearby population centers, including the town of Klyuchi, which is located some 30 kilometers away from the Shiveluch's foothills. A senior researcher at the Geophysical Service said the trail of ash had shifted northwards from the volcano where there are no townships of villages. In the meantime, volcanic dust and gasses may pose danger for aviation, and all the services and agencies concerned have been notified about it. The Shivelush is Kamchatka's northernmost active volcano.Its absolute elevation point is located at 3,283 meters above sea level. The absolute elevation point of the volcano's active part, known as Molodoi Sheveluch, is found at 2,500 metes above sea level, and its crater has the diameter of 1.5 kilometers. Molodoi Sheveluch became active in September 1980. It is subject to permanent observation for 30 years by now. According to expert assessments, the volcano does not pose any risk for the Kamchatkan population centers at the moment. (Itar-Tass)

Kizimen erupts again
Hot lava has flown down the eastern slope of a volcano called Kizimen, on the Kamchatka Peninsula in the Far East of Russia.

The ash plume stretches for 15 kilometers and is a threat to aviation, according to the Institute of Volcanology and Seismology of the Far East District.

Kizimen is one of 29 active volcanoes in Kamchatka and it became active in July of last year after 80 years of "silence."

Plumes of ash and hot gas jetting out of Kizimen volcano on Russian Kamchatka Peninsula have spread more than 15 km eastward as eruption continues. Giant columns of steam and ash shot up to 500 meters above the crater. Ash plumes have spread more than 15 km eastward of the volcano. Ash plumes, poisonous to human and animals, can also pose threats to aviation as fallen ash particles may cause mechanical problems and bring down airplanes. Kizimen is one of 29 active volcanoes in Kamchatka.

Eastern Russia volcano blows more ash
MOSCOW, Aug. 14 (UPI) -- Scientists said ash continued to billow from a volcano in Russia's Far East, which could have an effect on international air traffic in the region.

The Shiveluch volcano on the Kamchatka peninsula was pushing ash as high as 6,000 meters (20,000 feet) and creating "light-intensity" tremors on the ground lasting as long as 40 minutes, the Far Eastern Institute of Volcanology and Seismology said in a written statement.

No towns in the area were considered threatened by the ash fall.

Shiveluch has been erupting periodically since 2009. The size of the mountain's crater has grown 50 percent in that period, RIA Novosti said Sunday.

quote:

Kizimen spews ash 7km high
The Kizimen volcano on Kamchatka Peninsula is spewing ash plumes to a height of more than 7 kilometres. It is reported to be dangerous to aircraft. Small abrasive particles of volcanic ash can get into the aircraft mechanisms, causing the plane to crash.

The volcano has been assigned the highest, red hazard code to aviation. According to scientists, the erupting volcano presently does not pose any threat to the public.

Bezymianny volcano might be close to an eruption
The remote Bezymianny volcano in Kamchatka might be close to an eruption, as its seismic activity is continuously increasing, the Russian Institute of Volcanology and Seismology (KVERT) reported yesterday.
Strong ash explosions up to 42,640 ft (13 km) a.s.l. are possible at any time. Ongoing activity could affect international and low-flying aircraft.Seismic activity began to increase on February 12, when about 7-19 weak seismic events were registered each day until 29 Feb.
During 1-5 March, this number increased to about 25-43 weak seismic events and episodes of volcanic tremor. KVERT warns that the activity might signal a buildup towards a larger eruption.
According to satellite data, both size and brightness of a thermal anomaly (a growing lava dome) at the summit abruptly increased on 2 March and continues to increase.

quote:

Bezymianny on Red Alert
Bezymianny: KVERT placed this active Kamchatka volcano (right) on Red Alert status over the last few days after a sharp and sustained increase in seismic activity. They also noted a sizable increase in size and temperature of the thermal anomaly seen at the summit of the volcano (observed by satellite), suggesting that new, hot magma is very close/at the surface. Put these two things together and KVERT suggests that “strong ash explosions up to 43,000 ft (13 km) a.s.l. possible at any time during the next 24 hours.” It has been about 11 months since the last explosive eruption at Bezymianny – and if anything does occur, you can see if the Bezymianny webcam is operating to catch a glimpse.

Russian volcano spews ash 9500 meters in the air
Russia’s northernmost active volcano is churning out ash to a height of 9,500 meters (over 31,000 feet) in the country’s Far East, local scientists reported on Tuesday. The 3,283-meter (10,771-foot) Shiveluch volcano increased activity in May 2009 and has been periodically spewing ash from three to ten kilometers. “A powerful eruption of ashes took place 05.59 a.m. local time [17:59 GMT on Monday], a source at the Far Eastern Institute of Volcanology and Seismology said. The official said the column of ashes could be clearly seen from a distance of 40 kilometers spreading to the east. “It is the most powerful eruption this year,” the expert said. According to scientists, the volcanic activity over the past two-three years has significantly altered the contour of the volcano with the crater increasing in size by 50% and the slopes becoming far steeper than before. Although the current eruption poses no immediate threat to nearby settlements, the ensuing ash fallouts could be hazardous to health and the environment. The clouds of volcanic ash could also pose threat to air traffic because the tiny particles cause problems with aircraft engine turbines

Lava dome growth and effusion of a viscous lava flow continue at Shiveluch volcano, accompanied by moderate fumarolic activity and incandescence. Satellite imagery showed a thermal anomaly over the volcano all week.

Eruption's at four cinder cones producing fluid lava flows on the S part of the fissure on the flank of Tolbachik continues. A large thermal anomaly on the N part of the fissure was detected on satellite imagery. Gas and ash plumes from Tolbachik rose to heights of 4 KM a.s.l.

A lava flow continues to extrude on the east flank of Kizimen volcano, accompanied by incandescence, hot avalanches and strong gas and steam activity. Two new lava flows were detected on the SE flank of the volcano by satellite data. A thermal anomaly was also observed.

Possible ash eruptions from Karymsky volcano were detected in the past week with ash plumes possible rising to a height of 2.5 KM a.s.l. A thermal anomaly was detected at the volcano on the 11 and 14 January.

Strombolian activity continues at Kliuchevskoi volcano. This was accompanied by gas and steam activity from the summit and incandescence. Thermal anomalies were detected on 11 and 13 Janaury.

A viscous lava flow continued to effuse from the flank of the lava dome at Bezymianny volcano. Weak gas and steam activity were observed. A thermal anomaly was detected on the volcano on January 11 and 13.

Gas and steam activity was observed from Gorely on 10 and 12 January.

Gas and steam activity were noted from Chirpoi volcano on January 9 and 11.

A thermal anomaly and strong gas and steam activity were noted from Medvezhia volcano on January 11.

Video: Rare glimpse of volcanic activity in Russia's Far East

quote:

Four volcanoes currently erupting on Kamchatka
Volcanic eruptions are hardly a rarity. It seems that a new one goes off every few weeks or so somewhere in the world. But a string of four volcanoes erupting in close proximity to one another is virtually unheard of. That, though, is what has taken place in recent weeks on the Kamchatka Peninsula in Russia’s Far East.

Four different cones and mountains, all within 180 kilometers (110 miles) of each other, have been active simultaneously since late November. Given that volcano experts don’t believe that the four volcanoes are being fed from the same magma source, the parallel eruptions would seem to be the geological equivalent of winning the lottery. That volcanoes erupt in Kamchatka is, of course, hardly news.

The peninsula, which has a total land mass that is slightly larger than Germany, is one of the most active parts of the infamous “Ring of Fire,” the zone of volcanic and seismic activity that encircles the Pacific Ocean. Three tectonic plates — the North American Plate, the Okhotsk Plate and the Pacific Plate — collide beneath Kamchatka, with the peninsula’s coastal range boasting 30 active volcanoes. All four of the volcanoes now erupting have shown significant activity in recent years.

Most recently, Tobalchik began spewing lava on Nov. 27 of last year, creating the impressive lava flows visible in the 360 degree video taken by Airpano.

Shiveluch, the northernmost of the four, prefers shooting columns of ash high into the air, which it has been doing on a regular basis during the last four years since a magma dome in its crater exploded.

Besymjanny awoke with a bang in the 1950s following 1,000 years of dormancy and has been active since then, with huge clouds of ash rising on a regular basis.

Finally, the southernmost of the quartet, Kisimen, has been erupting regularly since 2010, and there is concern that it could perform a repeat of the violent explosion which sheered of half of the mountain some 1,300 years ago.

quote:

In the extreme northeast region of Russia is the Kamchatka Peninsula. Familiar to people who play the board game Risk, Kamchatka is a huge mass of land sticking out into the north Pacific, and sitting on the peninsula is a cluster of volcanoes, some of them among the most active on the planet.

The biggest of these is Klyuchevskaya Sopka, a monster stratovolcano towering over 4750 meters (15,500 feet) high. It’s also the most active, having been more-or-less erupting continuously since the late 1600s. It’s erupted a dozen times just since 2000!

On Oct. 20, 2013, the Landsat 8 Earth-observing satellite flew over Klyuchevskaya, capturing a tremendously long plume of ash as well as two separate lava flows moving down the volcano’s flanks:

Als afsluiter daarna ook dus nog de Avachinsky beklommen. Tijdens de trekking ook nog een voortop van de Khodutka beklommen (en in zijn hotsprings gelegen), eigenlijk iedere dag wel zicht op vulkanen in de omgeving, erg bijzondere reis en belevenis. Helaas geen echte eruptie gezien (alle echte uitbarstingen van dat moment waren zo'n 800 km naar het noorden) al begon Gorely wel behoorlijk te roken toen we uit de Mutnovksy kwamen lopen maar dat had met gassen en het weer te maken ofzo, wel erg bijzonder gezicht zeker omdat ons kamp aan de voet van de Gorely stond en we de volgende dag Gorely zouden beklimmen. Het leek iig op een eruptie

Het was dus een behoorlijk vulkaan georiënteerde reis en het is een erg bijzonder deel van de wereld. Nu daar geweest te zijn maakt het toch extra bijzonder om de berichten over nieuwe vulkaanuitbarstingen daar te volgen, zo was er onlangs deze nog:

Shiveluch Volcano is continuing to erupt in New Year

On the 8th of January at the Shiveluch Volcano were recorded ash explosions in 5 kilometers high under the sea level, as announced the Emergence Control Ministry with the reference to satellite data of “Kvert” group. Ash cloud was spread in the northern direction from the giant.

According to the data of the Emergence Control Ministry, there were no ashes near the villages close to the Volcano. Nevertheless, travel companies are recommended to keep from tours organization to the volcano, and tourists are better to keep from visiting the nearest places to the volcano. The notice was also related to the aviation as well. Shiveluch Volcano awarded orange aviation code of dangerous for air crafts.

Shiveluch Volcano is located in 450 km to the east-north from Petropavlovsk-Kamchatsky city. Volcano’s height is 3 283 km. It is one of the north and active volcano in Kamchatka. It is constantly under observation. The Volcano erupts about ten years with short periods of calm.

Northwest 'dirt' may be from Russian volcano
People in Washington state, Oregon, and Idaho got a strange surprise a couple of days ago, when their cars and houses were covered with a strange dirty substance that fell from the sky during a rain shower, according to local news reports.

The event was sufficiently freaky that the National Weather Service’s Spokane office tweeted this picture, and said that it was collecting samples to send to a lab for analysis. Under a microscope, the same looks ever weirder.

NEWS: Volcano Sparks New Type of Lightning

Initially, NWS thought the dirt might be from a storm in Nevada, which also dumped what appears in photos to be an odd milky or gray-colored dust, according to the service’s Inland Northwest Weather Blog. But since then, even stranger hypotheses have emerged. The Walla Walla County, Wash. emergency management agency, for example, suggested on its Facebook page that the ash is likely from Volcano Shiveluch in Kamchatka Krai, Russia, some 4,000 miles away. Volcano Shiveluch spewed an ash plume about 22,000 feet high in late January. In that scenario, winds blew the dust across the northern Pacific, where it was picked up by a storm system in the U.S. Northwest and mixed with rain clouds.

Another possible explanation, offered by CNN meteorologist Derek Van Dam, is that the dust is coming from the eruption last week of a volcano in southwestern Colima, Mexico, about 2,000 miles away from Washington state.

Even though the Russian and Mexican volcanoes are thousands of miles away, it’s not that unusual for volcanic ash to be distributed far and wide across continents, as this Wired article explains.
