The eruption of an Icelandic volcano that sent a huge plume of ash into the atmosphere and caused sweeping disruptions of air traffic over Great Britain and Scandinavia today will likely dissipate in the next several days, according to a University of Colorado at Boulder atmospheric scientist. Professor Brian Toon, chair of CU-Boulder's atmospheric and oceanic sciences department, said the plume created by the eruption of the Eyjafjallajokull Volcano contains tiny rock particles made up of...

European air travel was in a state of chaos early Friday morning, as the continued eruption of ash from a volcano in Iceland has forced airports across the continent and in the UK to close. According to Patrick Donahue of Bloomberg.com, airports in Belgium, the Czech Republic, Denmark, Finland, France, Germany, the Netherlands, Norway, Poland, and Sweden were closed as of 7:00am CDT. Furthermore, Vienna Airport in Austria was scheduled to be closed at 6:00pm local time, and many flights out...

The erupting Icelandic volcano that disrupted air traffic across Europe early Thursday worsened as the day went on, causing concern for health authorities in several countries. The volcano, which is located under the ice cap of the Eyjafjallajokull glacier, began erupting early Wednesday morning. As of 5:00pm CDT on Thursday, it not only remained active, spewing forth massive amounts of ash and smoke some 40-hours later, but started to grow even more intense, according to what University of...

The eruptions of "supervolcanoes" on Earth's surface have been blamed for causing mass extinctions, belching large amounts of gases and particles into the atmosphere, and re-paving the ocean floor. The result? Loss of species, increased greenhouse gases in the atmosphere, and changes in ocean circulation. Despite their global impact, the origin and triggering mechanism of these eruptions remain poorly understood. New data collected during a recent Integrated Ocean Drilling Program (IODP)...

Ancient goliaths blamed for multiple mass extinctions "Supervolcanoes" have been blamed for multiple mass extinctions in Earth's history, but the cause of their massive eruptions is unknown. Despite their global impact, the eruptions' origin and triggering mechanisms have remained unexplained. New data obtained during a recent Integrated Ocean Drilling Program (IODP) expedition in the Pacific Ocean may provide clues to unlocking this mystery. To explore the origins of these seafloor giants,...

WASHINGTON, April 8 /PRNewswire-USNewswire/ -- For the first time, scientists have detected clear signs of recent lava flows on the surface of Venus. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) The observations reveal that volcanoes on Venus appeared to erupt between a few hundred years to 2.5 million years ago. This suggests the planet may still be geologically active, making Venus one of the few worlds in our solar system that has been volcanically active within the...

For the first time, scientists have detected clear signs of recent lava flows on the surface of Venus. The observations reveal that volcanoes on Venus appeared to erupt between a few hundred years to 2.5 million years ago. This suggests the planet may still be geologically active, making Venus one of the few worlds in our solar system that has been volcanically active within the last 3 million years. The evidence comes from the European Space Agency's Venus Express mission, which has been in...

A NASA research team is using the latest advances in satellite artificial intelligence to speed up estimates of the heat and volume of lava escaping from an erupting volcano in Iceland. On March 20, 2010, Iceland's Eyjafjallajökull volcano (pronounced "AYA-feeyapla-yurkul,") awakened for the first time in 120 years, spewing still-active lava fountains and flows. That day, a NASA "sensor web" -- a network of sensors on the ground and aboard NASA's Earth Observing-1 satellite, alerted...

Volcanic activity more than 200 million years ago may have helped dinosaurs become and remain the world's dominant species by causing the mass extinction of rivals, researchers claim in a recent study. The paper, which was completed by a five-person team of researchers from the United States and Taiwan and published in the Proceedings of the National Academy of Sciences (PNAS), suggests that it was mass volcanic eruptions that wiped out the crurotarsans, the crocodile-like creatures that were...

A volcano in the southern part of Iceland has erupted for the first time in nearly two centuries, forcing hundreds of people to flee their homes and creating concern that a second, more destructive eruption might soon be on the way. The eruption occurred just before midnight Saturday, local time, at the Eyjafjallajokull volcano. Officials declared a state of emergency in the area, advising residence of Hvolsvollur and Vik to evacuate, as the volcano fired ash and molten lava into the night...

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...

Eldfell
2014-04-08 12:54:37

Eldfell is an active stratovolcano that is located in Iceland on the island of Heimaey, in the Vestmannaeyjar archipelago. It reaches an elevation of 656 feet and was created during a volcanic eruption on the east side of the island in 1973. Its name means Mountain of Fire in the Icelandic language. Iceland is an area with a high frequency of volcanic activity because it is located on top of the Iceland hotspot and beside the Mid-Atlantic Ridge. So many eruptions occur here that it is thought...

Kīlauea
2014-04-08 12:33:13

Kīlauea is an active shield volcano that is located on the island of Hawaii and is located within Hawaii Volcanoes National Park. This volcano, which reaches an elevation of 4,091 feet, is one of five volcanoes that form the island and it is the most active. It is thought to be between 300,000 and 600,000 years old and is the second youngest of all the Hawaii volcanoes. It was formed when the Pacific tectonic plate moved over the Hawaiian hotspot and like other Hawaiian volcanoes, it began...
