After a volcanic eruption that occurred around 250 million years ago, hundreds of millions of years before dinosaurs were wiped off the face of the planet, almost 95 percent of all primitive life living in the ocean and 70 percent of all animals evolving on land were wiped out. Researchers at the University of Calgary in Alberta, Canada have discovered evidence suggesting that massive volcanic eruptions at the time burnt significant levels of coal, producing suffocating clouds of ash and...

The eruption of the Icelandic volcano Eyjafjoell earlier this year followed a long, threatening warming period in which the volcano rumbled and bulged, scientists reported on Wednesday. Vulcanologists from the US, Iceland, Sweden and the Netherlands studied satellite images and checked data from GPS movement monitors to construct a gradual representation of events. "Several months of unrest preceded the eruptions, with magma moving around downstairs in the plumbing and making noise in the...

Defying models, some regions drier, others wetter Scientists have long known that large volcanic explosions can affect the weather by spewing particles that block solar energy and cool the air. Some suspect that extended "volcanic winters" from gigantic blowups helped kill off dinosaurs and Neanderthals. In the summer following Indonesia's 1815 Tambora eruption, frost wrecked crops as far off as New England, and the 1991 blowout of the Philippines' Mount Pinatubo lowered average global...

Scientists said Monday that torrents of water are pouring from a glacier that sits on Iceland's most active volcano, which indicates that the mountain is growing hotter and may be erupting soon. University of Iceland geophysicist Pall Einarsson told the Associated Press (AP) on Monday that the flood which started Thursday at the Grimsvotn volcano is similar to the one in 2004 that lasted five days and ended with an eruption that disrupted European air traffic. Millions of air travelers...

Mount Merapi launched lava and hot ash into the skies for the fourth time in eight days Wednesday morning, sending villagers and refugees scurrying to move further away from the Indonesian volcano following its most intense eruptions yet. Reporting from Jakarta, Slamet Riyadi of the Associated Press (AP) said, "The eruption lasted more than an hour and shot searing ashes miles into the sky. Panicked people in [the] Umbulhardjo refugee camp screamed and children cried when they saw the...

Nevada and Hawaii researchers complete study of Kilauea health clinic records Kilauea Volcano on Hawaii's big island has been erupting on its east rift since 1983. But, in March 2008, an additional eruption vent opened at the volcano's summit, resulting in about triple the amount of sulfur dioxide gas (SO2) emissions drifting to the local community of Ka'u, raising health concerns over the risks associated with exposure to "vog," as the islanders refer to this volcanic air pollution. A...

Scientists are crediting satellite imagery with helping to predict where volcanic eruptions could strike. It is well known that earthquakes can stress Earth's crust and trigger subsequent quakes, but there has been no proof of this for volcanoes until now. In September 2005, a volcanic event in Ethiopia's Afar Desert forced magma up through rocks in a crack, known as a dyke, resulting in a 60-km-long tear in Earth's crust. Over the next four years, 12 more dykes were created in the same...

New research suggests that climate change following massive volcanic eruptions drove Neanderthals to extinction and cleared the way for modern humans to thrive in Europe and Asia. The research, led by Liubov Vitaliena Golovanova and Vladimir Borisovich Doronichev of the ANO Laboratory of Prehistory in St. Petersburg, Russia, is reported in the October issue of Current Anthropology. "[W]e offer the hypothesis that the Neanderthal demise occurred abruptly (on a geological time-scale) "¦...

Researchers working with the British Geological Survey (BGS) are studying ash samples collected from the Eyjafjallajökul volcano that could shed new light on the dispersion of volcanic ash following an eruption, according to a Tuesday report by BBC News. Neil Bowdler, a science reporter with the British news agency, reported that the samples were collected following the massive March eruption of the Icelandic volcano, and that they could help scientists find out why ash that was fine...

A better way to pinpoint where volcanic eruptions are likely to occur has been produced by an international team of geophysicists. Scientists from the universities of Leeds, Purdue, Indiana and Addis Ababa, investigated volcanic activity occurring in the remote Afar desert of Northern Ethiopia between 2005 and 2009. By studying a rare sequence of 13 magmatic events "“ where hot molten rock was intruded into a crack between the African and Arabian plates "“ they found that the...

Irazú Volcano, known as Volcán Irazú in Spanish, is an active stratovolcano that is located in Costa Rica. The origin of the volcano’s name is unknown, but it is thought to be a variant of the word Iztarú, which is the name of a village that was near the volcano, or a mixture of the words ara, meaning point, and tzu, meaning thunder. It is locally known as The Colossus due to large past eruptions. This volcano is located within Irazú Volcano National Park, which holds montane forests...

Rincón de la Vieja

Rincón de la Vieja is an active complex volcano that is located in northwestern Costa Rica. Its name, meaning The Old Woman's Corner, refers to a legend that says that a woman’s lover was thrown into the volcano by her father, after which she lived on the volcano as a recluse. This volcano reaches 6,286 feet in elevation and is the tallest volcano in Rincón de la Vieja Volcano National Park. Visitors were once permitted to climb up to the crater, but a recent eruption caused this area to...

Mount Hudson

Mount Hudson, also known as Volcán Hudson, is an active stratovolcano that is located in southern Chile, named after 9th-century Chilean Navy hydrographer Francisco Hudson. Its summit, which is covered in glaciers, holds a caldera that was created from a large eruption that occurred in 4750 BCE or 1890 BCE. Based on evidence found at the Los Toldos archaeological site, it is thought that the early eruption destroyed most settlements in the area at that time. Modern eruptions occurred in...

Nyamuragira

Nyamuragira is an active shield volcano that is located in the Democratic Republic of the Congo. This volcano, which is part of the Virunga Mountains, reaches an elevation of 10,033 feet and is the most active volcano in Africa. This volcano is shorter than Nyiragongo, which it shares an area with, and has a low shield profile. It holds a large amount of sulfur dioxide and is blamed for much of the volcano related sulfur dioxide content in the atmosphere. Nyamuragira has erupted over forty...

Imbabura Volcano
2014-10-04 17:36:59

Imbabura Volcano is an inactive stratovolcano that is located in Ecuador and is part of the southern Ring of Fire and one of many volcanoes created along an arc by the subductions of the Coolyo Plate underneath the South American Plate. This volcano was shaped by strombolian eruptions, which are less violent than plinian eruptions and are characterized by the expulsion of lapilli, lava bombs, and cinders as well as the accumulation of tephra around the point of eruption like a vent....
