Potential Eruption In Iceland Could Pump Acid Into European Airspace
2012-06-12 15:11:11

A modern recurrence of an extraordinary type of volcanic eruption in Iceland could inject large quantities of hazardous gases into North Atlantic and European flight corridors, potentially for months at a time, a new study suggests. Using computer simulations, researchers are investigating the likely atmospheric effects if a “flood lava” eruption took place in Iceland today. Flood lava eruptions, which stand out for the sheer amounts of lava and sulfurous gases they release and...

Warning Signs Of The 2011 Axial Seamount Eruption
2012-06-11 02:53:32

A team of scientists that last year created waves by correctly forecasting the 2011 eruption of Axial Seamount years in advance now says that the undersea volcano located some 250 miles off the Oregon coast gave off clear signals just hours before its impending eruption. The researchers´ documentation of inflation of the undersea volcano from gradual magma intrusion over a period of years led to the long-term eruption forecast. But new analyses using data from underwater hydrophones...

Volcanic Super-Eruptions A Quicker Threat Than Previously Thought
2012-05-31 05:03:53

Lee Rannals for RedOrbit.com Volcanoes capable of super-eruptions that could be catastrophic for civilizations have short fuses, according to new research conducted at Vanderbilt University. Super-eruptions are more than 100 times the size of ordinary volcanic eruptions like Mount St. Helens. These types of eruptions spew out super-heated gas, ash and rock, and are capable of leveling entire continents. Researchers say that there is evidence of one super-eruption that took place in...

Crystal Composition Could Predict Volcanic Eruptions
2012-05-26 05:03:51

By studying crystals formed in volcanic rock, experts may be able to predict an impending eruption up to a year in advance, researchers from the University of Bristol have discovered. According to a Thursday press release from the university, Dr. Kate Saunders and her colleagues used forensic-style chemical analysis to link seismic observations of a 1980 eruption at Mount St. Helens to the growth of crystals within the large underground pool of liquid rock beneath the volcano known as the...

The early April earthquake of magnitude 8.6 that shook Sumatra was a grim reminder of the devastating earthquakes and tsunami that killed tens of thousands of people in 2004 and 2005. Now a new study, funded by the National Science Foundation, shows that the residents of that region are at risk from yet another potentially deadly natural phenomenon — major volcanic eruptions. Researchers from Oregon State University working with colleagues in Indonesia have documented six major...

Scientists Observe Rapid Change In Underwater Volcano
2012-05-14 11:28:02

Lee Rannals for RedOrbit.com Researchers have been able to capture the rise and collapse of an underwater volcano in the Pacific Ocean for the first time. The team studying Monowai volcano near Tonga has recorded large changes in height of the volcano in just two weeks. The researchers gathered images by sonar on a ship, unveiling new details about the submarine mountains. There are as many as 32,000 underwater mountains that have been identified around the world, and the majority...

Was Little Ice Age Caused By Increased Volcanism In The Middle Ages?
2012-05-10 08:19:09

A large part of the Northern Hemisphere was in the midst of an unusual cold snap for nearly 500 years, from the Middle Ages through the early 19th century, in what scientists now call the “Little Ice Age.” A new study, published in the journal Geophysical Research Letters, has probed the longstanding mystery of when this event actually began, what caused it and how it was sustained for such a long period. Gifford Miller, a climatologist at the University of Colorado at...

Yellowstone: New Picture Emerges Of A More Active, Less 'Super' Volcano
2012-04-30 08:36:47

Brett Smith for Redorbit.com New research is casting doubts on the frequency or even the possibility of a ℠super-eruption´ that could blot out the sun from the Earth with a thick veil of volcanic ash. A joint research team from Washington State University and the Scottish Universities Environmental Research Centre said the biggest Yellowstone eruption on record was actually two different eruptions at least 6,000 years apart. According to the study published in the June...

NASA Satellite Captures Video Of Mexico's Popocatepetl Volcanic Ash Cloud
2012-04-23 09:20:33

[ Watch the Video ] Mexico's Popocatepetl Volcano has re-awakened and has been emitting gas and ash. NOAA's GOES-13 satellite has been viewing the ash cloud, and it was documented in a short new video released by NASA's GOES Project on Friday. NOAA's Geostationary Operational Environmental Satellite, GOES-13, captures visible and infrared images of weather over the eastern U.S. every 15 minutes, and spotted an ash and gas cloud streaming from Mexico's Popocatepetl Volcano over several...

Eruption Threat Level Increased At Volcano Near Mexican Capital
2012-04-21 05:40:16

The Popocatepetl volcano located outside of Mexico City has started spewing ash and fragments of glowing, molten rock thousands of feet down its slopes, forcing officials at one of the world's largest cities to increase the volcano's alert level, BBC News and the Associated Press (AP) are reporting. The volcano, which is also commonly referred to as 'Popo,' has been expelling small amounts of ash on an almost daily basis since entering a round of eruptive activity back in 1994, the AP...

Arenal Volcano
2014-08-28 11:31:44

Arenal Volcano, also known as Volcán Arenal, is an active stratovolcano that is located in northwestern Costa Rica. It can be found in Arenal Volcano National Park and was one of Costa Rica’s most active volcanoes until 2010. This volcano has a small crater and several eruptive vents and is the youngest of all active volcanoes in Costa Rica. Arenal Volcano has produced some violent eruptions, including the eruption of 1968, which covered three villages, killed eighty-seven people, and...

Nevado del Ruiz, also known as La Mesa de Herveo, is an active stratovolcano that is located along the border of the Colombian territories, or departments, of Caldas and Tolima. It reaches an elevation of 17,457 and is shaped like a cone. This volcano is protected within Los Nevados National Natural Park, along with many other volcanoes, and it is a popular tourist destination. Winter activities like skiing are conducted here as well as hiking and fishing. Nevado del Ruiz is part of the...

Galeras
2014-08-28 10:56:28

Galeras is a stratovolcano that is located in Nariño, a Colombian controlled territory. This volcano, which reaches a height of 14,029 feet, is highly active and the most active volcano in Colombia. It primarily contains andesite and holds two calderas that were created by eruptions in the past 560,000 years. Although it is shaped like a horseshoe, eruptions have caused a cone shaped structure to build up in one of the calderas. It was labeled a Decade Volcano in 1991, despite its recent...

Chaitén
2014-08-28 10:38:21

Chaitén is a volcanic caldera that is located in southern Chile that reaches an elevation of 3,681 feet. It is thought that this volcano once held a rhyolite obsidian lava dome that reached 3,156 in height, but this was destroyed after its most recent eruption in 2008. In the past, this volcano has released grey obsidian, which was used by pre-Columbian cultures to make many objects, some of which have been found 250 miles away from the volcano. Chaitén experienced the beginning of a new...

Villarrica
2014-08-19 11:03:54

Villarrica, also known as Rucapillán, is an active stratovolcano that is located in Chile and is protected within Villarrica National Park. This volcano is one of five known volcanoes to have a lava lake within its crater and it often produces strombolian eruptions that contain lava flows and incandescent pyroclasts. It is one of three volcanoes that occur along the Gastre Fault Zone, along with the less active Quetrupillán and Lanín volcanoes. During the Valdivia Interglacial, it...
