A better way to pinpoint where volcanic eruptions are likely to occur has been produced by an international team of geophysicists. Scientists from the universities of Leeds, Purdue, Indiana and Addis Ababa, investigated volcanic activity occurring in the remote Afar desert of Northern Ethiopia between 2005 and 2009. By studying a rare sequence of 13 magmatic events "“ where hot molten rock was intruded into a crack between the African and Arabian plates "“ they found that the...

Geologists reported on Sunday that a swarm of small earthquakes that struck western Saudi Arabia last year was actually the rumbling of a volcano. Over 30,000 minor quakes took place between April and June 2009 within an ancient solidified lava field called Harrat Lunayyir, which damaged some buildings near Al Ays and prompted the authorities to evacuate the 40,000 residents from the region. Most of the quakes measured less than two on the scale of magnitude, but several were hefty,...

The heat in the atmosphere of Venus, induced from a strong greenhouse warming, might actually have a cooling effect on the planet's interior. This counter-intuitive theory is based on calculations from a new model presented at the European Planetary Science Congress (EPSC) in Rome on Tuesday September 21st. "For some decades we've known that the large amount of greenhouse gases in the atmosphere of Venus cause the extreme heat we observe presently", explains Lena Noack from the German...

Experts say that another volcanic eruption on Iceland could happen again soon, but will likely cause much less chaos than the one that caused air traffic to shutdown earlier this year. The Eyjafjallajokull volcano, which began erupting on April 14, spewed enough ash into the atmosphere to cause the largest-scale European airspace shutdown since World War II. University of Iceland geologist Armann Hoskuldsson told an international conference in Keflavik that the event "was very unusual."...

Volcanoes display the awesome power of Nature like few other events. Earlier this year, ash from an Icelandic volcano disrupted air travel throughout much of northern Europe. Yet this recent eruption pales next to the fury of Jupiter's moon Io, the most volcanic body in our solar system. Now that astronomers are finding rocky worlds orbiting distant stars, they're asking the next logical questions: Do any of those worlds have volcanoes? And if so, could we detect them? Work by theorists at...

An Indonesian volcano that had been dormant for more than four centuries before erupting earlier this week has once again become active, launching a massive burst of ash some 10,000 feet into the air and forcing nearby villagers, many of whom had just returned home, to once again evacuate. According to Associated Press (AP) Writer Binsar Bakkara, the force of the eruption was "the strongest so far" and could be felt up to five miles away from the source, Mount Sinabung in North Sumatra. The...

A volcano in western Indonesia that has been dormant for more than 400 years erupted for the second straight day Monday, blasting hot ash more than a mile into the air and forcing the evacuation of 30,000 people in the region. Many villagers living along the slopes of Mount Sinabung in North Sumatra province wore masks as they packed up and headed to emergency shelters and churches, said Andi Arief, presidential advisor on disaster. Homes and crops around the area were covered in ash and...

Authorities in Colombia were forced to order the evacuation of thousands of residents after the Galeras Volcano erupted on Wednesday, but only a few took heed and headed for shelters, according to a recent Reuters report. Galeras, located in the Colombian Andes near the border of Ecuador, spewed ash over neighboring towns, but so far no injuries or damages have been reported by authorities after the latest eruption. About 8,000 residents live in the danger zone, but many often refuse to...

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...

Hualālai

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

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...
