The Puyehu volcano in southern Chile continues to erupt for a second day, spewing pumice and an ash cloud six miles high and three miles wide. Airline flights have been canceled in the region and more than 3,500 people stayed away from their homes near the volcano. Most of the residents in 22 settlements near the Puyehue-Cordon Caulle volcanic complex evacuated when the eruption began Saturday afternoon and were staying in government shelters or friends' homes. One group of 122 people was...

A 3-D model of a volcanic explosion, based on the 1980 eruption of Mount St. Helens in Washington state, may enhance our understanding of how some volcanic explosions occur and help identify of blast zones for potentially dangerous locations, according to an international team of volcanologists. "We took on the modeling of enormously complicated pyroclastic density currents, notably the classic, notorious May 1980 lateral blast that destroyed 500 square kilometers of forested terrain at Mount...

MOFFETT FIELD, Calif., May 26, 2011 /PRNewswire-USNewswire/ -- A team of NASA-funded researchers has measured for the first time water from the moon in the form of tiny globules of molten rock, which have turned to glass-like material trapped within crystals. Data from these newly-discovered lunar melt inclusions indicate the water content of lunar magma is 100 times higher than previous studies suggested.

A team of NASA-funded researchers has measured water from the moon that shows some parts of the lunar mantle have as much water as the Earth's upper mantle. The research, from Case Western Reserve University, Carnegie Institution for Science, and Brown University, shows 100 times more water than measured before. Scientists discovered water along with volatile elements in lunar magma trapped inside of crystals that are themselves trapped inside tiny volcanic glass beads. The team of...

About 500 flights were grounded on Tuesday after ash from an Icelandic volcano moved its way through Britain and towards northern Europe. The clouds caused flights in and out of Scotland, northern England and Northern Ireland to be cancelled. British Airways led the way in canceling flights as the ash-cloud from the Grimsvötn volcano spread eastwards. "Approximately 500 flights were cancelled from the approximately 29,000 that would have been expected today across Europe," said a...

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...

WASHINGTON, May 12, 2011 /PRNewswire-USNewswire/ -- New data analysis from NASA's Galileo spacecraft reveals a subsurface ocean of molten or partially molten magma beneath the surface of Jupiter's volcanic moon Io. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The finding heralds the first direct confirmation of this kind of magma layer at Io and explains why the moon is the most volcanic object known in the solar system.

NASA said on Thursday that its Galileo spacecraft has revealed a subsurface ocean of molten, or partially molten, magma beneath the surface of Jupiter's volcanic moon Io. The research is the first direct confirmation of this kind of magma layer at Io and explains why the moon is the most volcanic object known in the solar system. "Scientists are excited we finally understand where Io's magma is coming from and have an explanation for some of the mysterious signatures we saw in some of the...

Mount Nyiragongo
2014-08-28 11:22:30

Mount Nyiragongo is an active stratovolcano that is located in the Democratic Republic of the Congo. This volcano is part of the Virunga Mountains and is located in Virunga National Park. It reaches an elevation of 11,385 feet and has a crater that reaches 1.2 miles in width. This crater typically holds a lava lake that has varied between 2,000 and 10,660 feet in depth. It is not known how long this volcano has been active, but at least 34 eruptions have been recorded since 1882. Mount...

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...

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...

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...
