Photo Friday: Eruption at a Glacier Volcano in Russia

Spread the News:ShareKlyuchevskoy, a glacier-covered volcano on the Kamchatka Peninsula in eastern Russia, is erupting. The volcano, 4,750 meters in elevation, has had a history of extensive activity over the last 7,000 years. It has been emitting gas, ash and lava since April 3. Several organizations are closely monitoring its eruption. They note that ash explosions reaching 6 to 8 kilometers in height could occur at any time, affecting flights from Asia to Europe and  North America. Local impacts could also be extensive.

According to the video data, an intensification of the eruption was noted on 06 July: strong explosions sent ash up to 7.5 km a.s.l. According to satellite data by KVERT, a large bright thermal anomaly in the area of the volcano was observed all week, ash plumes drifted for about 350 km to the southwest, south and southeast from the volcano on 02-05 July; and dense ash plumes drifted for about 400 km to the southeast and east from the volcano on 06-07 July.” Enjoy these striking photos of Klyuchevskoy’s eruption and glaciated peaks below. volcano 2 Klyuchevskoy's usually snowy and glaciated peaks, with a plume rising over 6,000 meters.

Ecuadorean Eruption Sparks Fears of Glacier Floods

Spread the News:ShareAsh erupted from Ecuador’s glacier-covered Cotopaxi volcano last week after seventy quiet years. The debris shot five kilometres into the air, covering homes, cars, fields and roads as it descended, according to the Independent. Patricio Ramon, of Ecuador’s Instituto Geofísico, said the eruption was phreatic, meaning that molten rock encountered water, creating a forceful release of steam. “[I felt] in shock, not knowing what to do when I saw everything was moving. Then a strong smell of sulfur filled the mountain. Tourists were also concerned and wanted to leave as soon as possible,”  resident Franklin Varela told Ciudadana, an Ecuadorean radio station. eruption today at glacier-covered #volcano #Cotopaxi http://t.co/USjPXSmF9S in #Ecuador pic.twitter.com/rsd1p3ftrC — GlacierHub (@GlacierHub) August 14, 2015 Cotopaxi, Ecuador’s second highest volcano, peaks at 5,897 metres and lies 45 kilometres from the capital, Quito. Its glacier, also named Cotopaxi, is considered to be of significant economic, social and environmental importance, according to reports of the United Nations Environment Programme. Meltwater from the glacier provides Quito with water and hydroelectric power, but in the last 40 years, the ice has thinned by more than 38 percent.  Most of this retreat is attributed to climate change, but eruptions can exacerbate glacial retreat by rapidly melting ice and triggering floods. Researchers from Instituto Geofísico told El Universal they considered Cotopaxi one of the most dangerous volcanoes in the world due to its potential for lahars, or mudflows, often triggered by glacial melt. When Cotopaxi erupted in 1877, lahars travelled as far as 100 kilometres from the volcano.   #Cotopaxi volcano crater hot areas in #Landsat 8 thermal band on Aug 10. @JonathanStone10 @IGecuador @eruptionsblog pic.twitter.com/kj3bfZJjzT — Rudiger Escobar Wolf (@rudigerescobar) August 14, 2015 The most recent ash eruptions led to the evacuation of hundreds of residents and livestock from El Pedregal, a community close to the volcano, reported La Hora. Farmers have expressed concerns that the ash that fell on their livestock feed will harm their animals. Residents have been warned to avoid inhaling ash. Quito’s Mayor, Mauricio Rodas, told citizens he would hand out masks and told the city to remain calm.

On Saturday, Ecuador’s president, Rafael Correa, declared a state of emergency. The president’s announcement comes the same week as a series of strikes against his government’s labor policies and changes to the constitution that would allow him to run for president at the end of his term. The army and police have been dispatched and civil guarantees are temporarily suspended. “We declare a state of emergency due to the unusual activity of Mount Cotopaxi,” Correa said. “God willing, everything will go well and the volcano will not erupt.” Map in spanish showing the possible hazards of the #eruption at #Cotopaxi #volcano #Ecuador pic.twitter.com/ObBbnrXi1v — Roberto C.

Volcanic Eruption Leaves Dogs Stranded and Hungry

Volcanic Eruption Leaves Dogs Stranded and Hungry

Spread the News:ShareAs communities pick themselves up from a series of volcanic eruptions in southern Chile, stories of heartbreak and happy reunions emerge. Last week, glacier-covered Calbuco erupted three times, displacing thousands of local residents and animals. The eruptions sent ash 20 kilometers into the air, according to the BBC,  and triggered a series of mudslides, which followed the melting of glaciers and recent rainfall in the region. Hundreds of families were forced to leave behind their pets and efforts have since been launched to rescue lost animal companions. Many zones were deemed unsafe and families were unable to return, but in some cases, there have been happy reunions. “Our government’s commitment is not only to be concerned, but to actively meet the needs [of communities], so that they can return and resume normal life as soon as possible,” Chile’s president Michele Bachelet said at a press event. Some families are gradually returning to their towns to inspect the damage and see if anything can be salvaged. Residents are documenting their experiences on video and social media. One such video, shot in Ensenada by Claudio Domingo Hernandez Matamala and viewed more than 200,000 times on Facebook, shows an emotional reunion between one abandoned pet and his worried owners. The dog sustained some minor burns on his back but was otherwise alive and well. Watch the reunion here: Calbuco: mirá el emotivo reencuentro de una mujer y su mascota http://t.co/Gho4rp9dp8 — La Gaceta Salta (@LaGacetaSalta) May 2, 2015 Other reports haven’t been as joyous. Feral dogs attacked and killed five sheep evacuated from exclusion zones surrounding the Calbuco volcano. The local government has taken measures to protect animals and keep them in trailers away from dangerous dogs, but many animals are still stranded near volcanic activity. Officials say they are uncertain about how much livestock has died from inhaling volcanic ash, though reports suggest some have died from contaminated water. But not all dogs have taken to attacking livestock in their hunger. One dog, now nicknamed “Ceniza” or “ash,” was adopted by the military after contributing to rescue efforts. Ceniza boosts the moral of troops as they work to rebuild communities.

There are concerns that the ash will hurt crops and take a toll on residents’ livelihoods. “Now we have to think about the future,” Piedro Gonzáles, a resident of Ensenada, told Agence France-Presse. “We hope that in two months Ensenada can returnto normal. But it depends on whether the volcano can leave us alone.”     Spread the...

Will An Icelandic Volcano Erupt Under A Glacier In 2015?

Will An Icelandic Volcano Erupt Under A Glacier In 2015?

Spread the News:ShareA group of well-placed observers have warned the world about the possibility of a major volcanic eruption in Iceland in 2015. Steen Jakobsen, the chief economist of the Danish trading and investment firm Saxo Bank, and the bank’s strategy team have issued their “Outrageous Predictions” for the coming year. They state that these predictions are “independent calls on events that can upset global markets or politics. They are strategic in nature rather than an exercise in getting everything right, while our aim is to encourage alternative thinking.” An eruption of the Barðarbunga volcano could send a cloud of ash and noxious gasses that would threaten to block incoming solar radiation and cause crop failures across Europe, leading to rising food prices and political unrest. Even if the ultimate consequences of the eruption were not so severe, the fear of poor harvests could drive food prices skyward and create severe economic and political disruptions. Saxo Bank mentioned other possible threats in 2015, including a housing market crash in the UK, Japanese inflation reaching 5 percent, a spike in cacao prices that would make chocolate much more expensive, and the resignation of Mario Draghi, the current head of the European Central Bank. “The forecast is one of a series of “outrageous predictions” made by Denmark’s Saxo Bank for 2015” http://t.co/nFERxwnNE9 — Neil Jones (@Aelfrith) December 12, 2014 It might seem that these predictions are merely an effort of Saxo Bank to use improbable disaster scenarios to garner public attention during the news lull over the holiday season. But their track record is better than such a view would suggest. One of their predictions for 2014, “Brent crude drops to USD 80/barrel as producers fail to respond” came true, when oil prices fell below that benchmark on November 13 of that year. In 2011, three of Saxo Bank’s ten predictions proved to be correct: the yield on the U.S. 30-year Treasury bills fell below 3 percent, crude oil prices rose above $100 and then fell, and the price of gold surged past $1,800 an ounce. They did well with gold in 2013 as well, when the price of the metal, which had been rising steadily for more than a decade, tumbled and in December passed below $1,200 an ounce, as they predicted. Moreover, volcanoes can indeed emit enough ash to block solar radiation and cause crop failures. The 1783-84 eruption of Laki in Iceland led to low yields in France and other parts of Europe and was, as Saxo Bank suggested, a contributing factor to the French Revolution in 1789. The 1815 eruption of Tambora in Indonesia caused food shortages in Europe and North America, and probably in Asia as well. However, the Barðarbunga volcano and the associated Holuhraun lava field have been behaving in a fairly calm manner. Indeed, the Icelandic volcanologist Páll Einars­son has termed it a “peaceful eruption,” adding that, “it just keeps go­ing day af­ter day with lit­tle changes.” There are many signs of this orderly behavior. The movement of magma through subterranean passages shakes the earth in a steady rhythm, with several quakes reaching 5 on the Richter scale every month and many more less powerful ones. The volcanic caldera continues to subside, as magma flows away to new areas, where it can emerge. The fissures keeps on issuing significant amounts of lava. Holuhraun is reaching an area of 80 square kilometers, about the size of the island of Manhattan, and the volume of lava is more than a cubic kilometer. Fortunately, the lava has been moving to the north and east, away from the major...

Visualizing Iceland’s volcanos

Visualizing Iceland’s volcanos

Spread the News:ShareThere are few sights in nature as impressive as a fiery volcanic eruption. GlacierHub has featured many photos and stories from Iceland’s recent volcanic eruptions, and another useful way of understanding some of the more intangible aspects of volcanoes is through data visualization. One of the hot spots (if you’ll excuse the pun) in Iceland is the Bárðarbunga volcano near the center of the country. Each day, the Icelandic Met Office updates the aviation warning color for all of Iceland’s volcanoes. Green means everything is normal, red means an eruption is immanent and air travel must be grounded. Bárðarbunga has been “forever orange” for weeks now, even as other eruptions have come and gone. The gif shows the daily warning progression of Bárðarbunga and you can see just how the volcano has been at “heightened or escalating unrest with increased potential of eruption.” There are more concrete ways to visualize the eruption. We’ve posted a picture to our Twitter feed comparing the lava height to the Statue of Liberty. The University of Iceland overlayed a lava flow onto a map of the area. There are plenty of GPS data maps out there. Iceland Magazine helpfully related the lava flow to Manhattanites by showing it covers an area three times the size of Central Park. How about that? New #Holuhraun lava is now 3 times larger than NYC’s Central Park! http://t.co/lDzgBHdyrC pic.twitter.com/VzFX1klhsR — Iceland Magazine (@IcelandMag) September 3, 2014 Map overlays, size comparisons and seismic graphs are all well and good, but what if you’re a budding volcanologist? Elska is an Icelandic pop singer who makes music for children and families. In late August, she posted a cartoon drawing explaining the eruption to children, which included, among other things, anthropomorphized magma moving closer to the surface and a handy pronunciation of Bárðarbunga (hint: say baur-thar-boun-ga).
