Oost-Russische vulkaanuitbarstingen: Wereldwijde zorgen?

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.

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.

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.

As uit drie Russische vulkanen zorgt voor problemen in Alaska
As uit drie Russische vulkanen heeft voor geannuleerde vluchten gezorgd in de Amerikaanse staat Alaska. De as in de lucht belemmert het zicht van de piloten.
Volgens een woordvoerder van Alaska Airlines zijn tenminste vier vluchten uit veiligheidsoverwegingen niet opgestegen.

Drie vulkanen in Rusland, aan de andere kant van de Beringzee, spuwen volgens een medewerker van het Alaska Volcano Observatory nog steeds as. Verwacht wordt, dat dankzij de wind alle vliegtuigen vanaf zondag weer kunnen opstijgen en landen.
