After lying dormant underneath a glacier since 2004, a volcano in Iceland began spewing steam, ash and smoke into the upper atmosphere on Sunday. Despite the impressive show, this eruption is less likely to endanger air traffic as a similar eruption last did last year. Closing the main airport in the country as a precaution, pilots were warned to steer clear of Iceland as areas close to the Grimsvotn (GREEMSH-votn) volcano were plunged into darkness. Scientists, however, explain that another...

A new study finds that the closing of some European airports last year during and after volcanic eruptions in Iceland was the proper thing to do, and may have saved lives. The eruption of ash from Eyjafjallajokull resulted in the largest closure of European airspace since World War II, with losses estimated at around $2 billion. Concerns about aircraft safety during the eruptions were well founded, as ash particles from the initial phase of the eruptions were particularly abrasive, posing a...

The Kilauea volcano that recently erupted on the Big Island of Hawaii will be the target for a NASA study to help scientists better understand processes occurring under Earth's surface. A NASA Gulfstream-III aircraft equipped with a synthetic aperture radar developed by NASA's Jet Propulsion Laboratory in Pasadena, Calif., departed on Sunday, April 3, from the Dryden Aircraft Operations Facility in Palmdale, Calif., to the Big Island for a nine-day mission. The Uninhabited Aerial Vehicle...

A volcanologist said on Friday that Indonesia issued a red alert after Mount Karangetang on the island of Sulawesi erupted, sending lava and searing gas clouds down its slopes. "We raised the volcano's status to the highest red alert level today at 5:45 pm (1045GMT) and ordered an evacuation in three villages on the slopes," government volcanologist Surono told AFP. He said that the 5,850-foot mountain on the island off North Sulawesi oozed lava, heat clouds and debris reaching as far as...

A fissure on Kilauea Volcano on the Big Island of Hawaii sent lava spewing more than 60 feet into the air recently, and scientists continued to monitor the activity closely. Park rangers said that no homes were threatened in the latest blast and also cautioned campers and visitors to keep their distance while it continues to act up. Kilauea has been constantly erupting for the past 28 years. But according to geologist Janet Babb of the US Geological Survey (USGS), this weekend's activity...

Eruptions at a Hawaiian volcano have forced officials to close off part of a national park to visitors while geologists monitor eruptions and other seismic activity in the area. According to the Daily Mail, US Geological Survey (USGS) scientists working at the Hawaiian Volcano Observatory (HVO) have reported "a fountain of fire" at the Kilauea Volcano. The volcano in question is located near Napau Crater in Hawaii County, and began erupting Saturday afternoon. "That event was nearly...

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...

Irazú Volcano, known as Volcán Irazú in Spanish, is an active stratovolcano that is located in Costa Rica.

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...

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

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....
