No matter their size or shape, explosive volcanoes produce tremors at similar frequencies for minutes, days or weeks before they erupt. In the Feb. 24 issue of the journal Nature, researchers at Yale University and the University of British Columbia (UBC) describe a model that explains this strange phenomenon "“ and may help forecast deadly eruptions. When such volcanoes erupt they can shoot hot ash up to 40 kilometers into the atmosphere and cause devastating destruction when the ash...

Scientists said Thursday that a mud volcano in Indonesia is responsible for displacing more than 13,000 families, and shows no sign of stopping for the better part of the next quarter century, as it continues to emit flammable gas through a deepening lake of sludge. Underground pressure means the volcano -- located in Sidoarjo, East Java -- could continue to gush out gray mud until 2037, when volumes will become small and insignificant, according to a computer model. But gas will continue...

Scientists took samples in New Jersey for latest research Twenty thousand years of massive volcanic eruptions doubled the level of carbon dioxide (CO2) in Earth's atmosphere 200 million years ago, according to research by Rutgers geologists published recently in the journal Science. Morgan Schaller, Jim Wright and Dennis Kent report that the level of atmospheric CO2 went from about 2,000 parts per million to 4,000 parts per million and then shrank back to pre-eruption levels over the next...

Japan has established a one-mile barrier around a volcano on Mount Kirishima after it erupted scattering rocks and ash across the southern part of the country. The Meteorological Agency raised the volcanic alert to level 3 Thursday as ash continued to spew from Shinmoedake on Japan's southernmost main island of Kyushu.  Residents in the area have been banned from going within a mile of the volcano following its worst eruption in 50 years. Agency volcanologist Sei Iijima said the...

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...

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

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...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
