The volcanic eruption in Iceland that has put a halt to air traffic throughout much of Europe could also cause trouble for people with already significant breathing problems, according to the World Health Organization on Friday. The agency has yet to establish what health risks could be involved with this specific eruption, but once the ash clouds settle the effects on health could be dangerous and widespread. "Any particulate matter that is deposited, breathed into the lungs is dangerous...

If history is any indication, the erupting volcano in Iceland and its immense ash plume could intensify, says a Texas A&M University researcher who has explored Icelandic volcanoes for the past 25 years. Jay Miller, a research scientist in the Integrated Ocean Drilling Program who has made numerous trips to the region and studied there under a Fulbright grant, says the ash produced from Icelandic volcanoes can be a real killer, which is why hundreds of flights from Europe have been...

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...

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...
