On January 2, Mount Nyamulagira in the Democratic Republic of Congo erupted, spewing lava from its southern flank and raising concerns that the 100 000 people in the town of Sake could be under threat. Fears were also triggered in Goma as rumors circulated that an eruption was imminent at the nearby Nyiragongo volcano, which devastated the city in 2002. Following the eruption, scientists and local authorities have been using a long series of space images from ESA's Envisat, together with...

Spanish and French researchers have defined the age, location, size and geochemistry of the volcanoes of Gran Canaria during the Holocene, 11,000 years ago, in order to draw up a map of volcanic hazards for the island. The research shows that the area of greatest volcanic activity is one of the most heavily populated areas in the north east of the island, which has suffered 24 eruptions over the period studied. The team of French and Spanish scientists led by researchers from the University...

YARMOUTH PORT, Mass., Dec. 29 /PRNewswire-USNewswire/ -- As residents of the Philippines brace for the imminent eruption of the Mayon volcano, officials have asked the International Fund for Animal Welfare (IFAW) to help evacuate affected animals. At this time, there are an estimated 2,000 head of water buffalo, 1,000 head of cattle, 5,500 pigs, 19,000 poultry, and 4,600 dogs living near the volcano and in need of immediate evacuation. For the last two weeks, the 8,070-foot Mayon volcano...

Despite the growing infrequency of tremors in the Philippines' active Mayon volcano, experts say that a swell of magma is building up beneath it that could eventually be released in a powerful and dangerous eruption. State volcanologist Ed Laguerta has cautioned that residents of the surrounding areas should not be lured into returning home by the volcano's apparent return to dormancy.  An eruption could occur at any moment and could potentially devastate the countryside around it....

Government officials in the Philippines say that Mayon volcano could erupt violently within days, following a week of spectacular flows of lava and increasing volcanic quakes, The Associated Press reported. Some 3,000 villagers are still lingering around the volcano even after government warnings to leave the danger zone. Gov. Joey Salceda said tens of thousands of people have already been evacuated from the foothills of Mayon, which on Monday emitted lava fountains, powerful booming noises,...

Scientists have unveiled video footage of the deepest underwater volcanic eruption, at a site where sweltering 2,500-degree lava explodes into cold water nearly a mile below the ocean surface. Bob Embley, a marine geologist at NOAA's Pacific Marine Environmental Laboratory in Newport, Oregon, said, "It was very exciting. We've never seen anything like that on the ocean floor." The West Mata volcano, six miles long and four miles wide, rises one mile from the sea floor and sits 4,000 feet...

Like an angry dog, a volcano growls before it bites, shaking the ground and getting "noisy" before erupting. This activity gives scientists an opportunity to study the tumult beneath a volcano and may help them improve the accuracy of eruption forecasts, according to Emily Brodsky, an associate professor of Earth and planetary sciences at the University of California, Santa Cruz. Brodsky presented recent findings on pre-eruption earthquakes on Wednesday, December 16, at the fall meeting of...

On Wednesday, the infamous Mayon volcano in the Albay province of the Philippines let off some steam, oozing lava and spewing ash into the atmosphere and prompting local authorities to evacuate more than 30,000 residents from the surrounding cities. According the chief state volcanologist Renato Solidum, the eruption was the 40th to occur in the last 400 years and consisted of five separate explosions"”the largest of which sent an plume of ash some 550 yards into the air from the top of...

A new study provides "incontrovertible evidence" that the volcanic super-eruption of Toba on the island of Sumatra about 73,000 years ago deforested much of central India, some 3,000 miles from the epicenter, researchers report. The volcano ejected an estimated 800 cubic kilometers of ash into the atmosphere, leaving a crater (now the world's largest volcanic lake) that is 100 kilometers long and 35 kilometers wide. Ash from the event has been found in India, the Indian Ocean, the Bay of...

Plinian volcanic eruptions are notoriously destructive. These very powerful eruptions often occur after long periods of quiescence and are preceded by relatively short periods of seismic restiveness. Volcanoes that tend to show this kind of behavior include Mount Vesuvius in Italy, Mt. Pinatubo in the Philippines and Mt. St. Helens in the USA. Professor Donald Dingwell of Ludwig-Maximilians-Universität (LMU) in Munich, together with Professor Jonathan Castro of the University of...

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.

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...
