A central Indonesian volcano that first started erupting last Thursday shot hot ash and smoke into their air again on Sunday in what the Telegraph considers "it's most powerful eruption yet." Mount Lokon, which is located on northern Sulawesi island, is a 5,184 foot volcano that until this past week had not erupted since 1991. Thousands of people were forced to evacuate from a two-mile zone surrounding the volcano, which according to BBC News shot ash, sand, and rocks some 4,800 feet into the...

One of Iceland's most active and most feared volcanoes looks like is getting ready to erupt, with measurements indicating magma movement, according to Icelandic experts on Wednesday, raising fears of a new ash cloud disrupting air traffic in Europe and abroad. The Hekla volcano, dubbed by Icelanders in the Middle Ages as the "Gateway to Hell," has erupted some 20 times over the past 1000 years, with the most recent eruption occurring on February 26, 2000. Hekla is close to the ash-spewing...

Latest research into the age of volcanos in Western Victoria and South Australia has confirmed that the regions are overdue for an eruption, potentially affecting thousands of local residents. Using the latest dating techniques, scientists from the University of Melbourne's School of Earth Sciences and the Melbourne School of Engineering have calculated the ages of the small volcanoes in the regions and established the recurrence rate for eruptions as 2,000 years. With the last volcano...

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...

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...

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...

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

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...
