Image 1 - NASA: No Evidence Of 2012 Supervolcano
2011-11-15 11:46:51

NASA said on Tuesday that there is no evidence of a massive supervolcano erupting in 2012, despite what some may believe. A supervolcano refers to an explosive volcanic eruption that eject about ten thousand times the quantity of magma and ash that Mount St. Helens expelled in 1980. NASA said Earth's surface has preserved clues of many massive supervolcanoes through hollowed-out calderas-craters that can be as big as 60 miles across after a volcano collapses from emptying out its entire...

Undersea Volcano Forming New Canary Island
2011-11-12 06:25:39

A new Canary Island is rising to the surface before our very eyes, and the first images of the infant volcano that is slowly coming up to the surface in the Spanish archipelago emerged on Friday. According to the Daily Mail, "Magma off the Canary Island of El Hierro has been spewing 20 meters high as the sea boils with a smell of sulfur“¦ As it grows and gets closer to the surface, more and more debris such as stones start to shoot out of the volcano which, until now, has only...

African Volcano Erupts With Impressive Show
2011-11-09 09:59:56

Africa´s most active volcano Nyamuragira, located in the Democratic Republic of Congo, erupted last weekend throwing off clouds of ash and orange smoke, AFP reports. Located in the eastern areas of Virunga National Park, the volcano continues to erupt but was not considered a threat to locals or to the mountain gorillas living in the park, said Congo´s Center for Research and Natural Sciences. “A fountain of lava, smoke and ash came out of a fissure on the side” of...

Chilean Volcano Could Have Major Eruption In Hours Or Days
2011-10-28 11:41:59

A volcano in Chile has released three columns of steam and ash that combined into a cloud of over 3 miles high on Friday. Officials in the country evacuated 119 people from the Hudson Volcano area, as other nearby residents prepared to flee due to melting snow and ice becoming a flood issue. Chile's national geology service said that the steam and ash was coming from three craters, ranging from 650 feet to 1,600 feet wide.  The service said that a major eruption could occur...

Image 1 - Fiery Volcano Give Researchers A Geologic Glimpse Into Land That Time Forgot
2011-10-20 09:31:50

[ Watch the Video ] The first scientists to witness exploding rock and molten lava from a deep sea volcano, seen during a 2009 expedition, report that the eruption was near a tear in the Earth's crust that is mimicking the birth of a subduction zone. Scientists on the expedition collected boninite, a rare, chemically distinct lava that accompanies the formation of Earth's subduction zones. Nobody has ever collected fresh boninite and scientists never had the opportunity to monitor...

Another Icelandic Volcano Threatening Eruption
2011-10-16 04:42:55

An Icelandic volcano, dubbed by Daily Mirror reporter Mike Swain as "one of the most feared volcanoes in the world," could be close to a major eruption that would "dwarf" those originating from the nearby Eyjafjallajokull last year. In 2010, the Eyjafjallajokull eruptions created an ash cloud which left planes grounded, stranded travelers, and ultimately cost the European economy more than $1.5 billion. Even so, that eruption was classified as a minor one. Katla, the volcano currently...

Image 1 - Undersea Volcanic Eruptions Continue Near Canary Islands
2011-10-14 08:46:24

Two volcanic eruptions were confirmed on Wednesday near the Canary Islands, forcing at least 500 people to spend the night outside of their homes after precautionary evacuations were ordered by local authorities. These eruptions follow similar earth movement on Monday of the same week. “I confirm the existence of two points of volcanic eruption at El Hierro,” Laura Otero, a spokeswoman for the local authorities, told AFP. The first eruption occurred at a depth of 2,300...

Scientists Find Possible Trigger For Volcanic 'Super-eruptions'
2011-10-13 03:35:17

The "super-eruption" of a major volcanic system occurs about every 100,000 years and is considered one of the most catastrophic natural events on Earth, yet scientists have long been unsure about what triggers these violent explosions. However, a new model presented this week by researchers at Oregon State University points to a combination of temperature influence and the geometrical configuration of the magma chamber as a potential cause for these super-eruptions. Results of the...

Tenerife Landscape Reveals Explosive Past
2011-10-03 04:51:52

Volcanologists from the University of Leicester have uncovered one of the world's best-preserved accessible examples of a monstrous landslide that followed a huge volcanic eruption on the Canarian island of Tenerife. Seven hundred and thirty-three thousand years ago, the southeast slopes of Tenerife collapsed into the sea, during the volcanic eruption. The onshore remains of this landslide have just been discovered amid the canyons and ravines of Tenerife's desert landscape by...

Scientists Concerned By Continued Eruptions At Alaskan Volcano
2011-09-18 04:41:53

  The two-month long, low-level eruptions occurring at a volcano in Alaska's Aleutian Islands have volcanologists worried that there could be a larger eruption forthcoming, Yereth Rosen of Reuters reported on Friday. The volcano causing concern is Cleveland Volcano (also known as Mount Cleveland), a 5,676-foot peak located less about 940 miles southwest of Anchorage. As previously reported here on RedOrbit, an eruption warning was issued by the Alaska Volcano Observatory in late...

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

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...
