As Iceland's Grímsvötn volcano spews ash high into the atmosphere, satellite observations are providing essential information to advisory centers assessing the possible hazards to aviation. The Grímsvötn volcano in southeast Iceland, which had been dormant since 2004, started erupting in the evening of 21 May. As a consequence, the country's airspace has been closed. Memories are still fresh of the chaos caused by the Eyjafjallajoekull eruption...

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...

Hualālai
2014-04-10 12:06:55

Hualālai is a dormant shield volcano that is located on the island of Hawaii and is one of five volcanoes that form the island. It reaches an elevation of 8,271 feet and is thought to have emerged from the sea about 300,000 years ago, making it the third youngest volcano on the island. Its shape is rough compared to younger volcanoes and it holds three rift zones that are covered with over one hundred cinder cones and spatter cones. Although it does not hold a caldera at its summit, it does...

Zubair Group

Zubair Group, also known as Zubayr Group or Al Zubair Group, is a chain of volcanic islands belonging to Yemen that are located on top of a shield volcano in the Red Sea. Zubair Group The largest island, known as Zubair, is among the youngest islands, which also include Saba, Saddle, and Haycock. The shield volcano underneath the islands began a period of eruptions and eventually quieted down, followed by a period of explosive and effusive eruptions that formed the islands that are present...

Kohala
2014-04-10 10:03:58

Kohala is an extinct shield volcano that is located on the island of Hawaii and reaches an elevation of 5,480 feet. It is one of five volcanoes that comprise the island of Hawaii and is thought to be about one million years old, although it only emerged from the sea about 500,000 years ago. Because its last eruption is thought to have occurred about 120,000 years ago, based on studies conducted on hardened lava flows, this volcano is not thought to pose a threat to inhabitants on the island....

Askja
2014-04-09 16:13:20

Askja is an active stratovolcano that is located in the isolated central highlands in Iceland. It reaches an elevation of 4,974 feet and its name literally means caldera, or box, in the Icelandic language. The area can only be reached during a period of a few months and because it located in the rain shadow of the Vatnajökull glacier to the northeast, it only receives 17.7 inches of rain per year. One of Askja’s smaller craters holds a lake known as Öskjuvatn, which is often frozen over...

Santa María Volcano

Santa María Volcano is an active stratovolcano that is located in Guatemala and is part of the Sierra Madre, a string of volcanoes that stretches across the western side of Guatemala. The volcanoes in this string were formed by subduction activity, when the Cocos Plate moved under the Caribbean Plate. An eruption in 1902 produced a crater that now holds a lava dome known as Santiaguito, which was created during another eruption in 1922. These domes hold active vents and in 1929, part of the...
