While the ongoing eruption of a volcano in Iceland has caused havoc for local farmers and travelers throughout Europe, a possible eruption of a much stronger volcano at the Yellowstone National Park would be potentially devastating, a representative from the U.S. Geological Survey (USGS) told reporters on Monday. "The impact would be severe," Bill Burton, a volcanologist with the agency, told the AFP news agency. Fortunately, he adds, "The next major eruption for Yellowstone, if you have a...

As ash caused by a volcanic eruption crippled European air travel for a fourth straight day on Sunday, hope that the travel restrictions could soon be lifted came in the form of a few successful test flights. On April 18, a British Airways Boeing 747 jumbo jet successfully flew through the cloud of volcanic ash, travelling from Heathrow Airport in London out over the Atlantic Ocean during a three hour flight. A British Airways spokesman and told the AFP, "The conditions were perfect and the...

In the past, volcanic eruptions have had a cooling effect on the Earth's climate, but the recent Icelandic eruption is too small to provide any relief from manmade global warming, scientists said on Friday. The biggest cooling event of the last 30 years was the 1991 eruption of Mount Pinatubo, which cooled the Earth's surface by nearly 1 degree Fahrenheit over the following year. This, in turn, was enough to offset the impact of greenhouse gases from 1991 to 1993. The Mount St. Helens...

Volcanic ash  fall could contaminate Iceland's drinking water in certain areas due to the ongoing Eyjafjallajokull eruption. Health officials also warned that the biggest health risk would be to livestock. "It is important to prevent the ash from reaching water supplies, both for public and animal health reasons and for safe milk production," Halldor Runolfsson of the Icelandic Food and Veterinary Authority told AFP. Most of Iceland's water supply comes from underground sources,...

Thousands of planes are grounded across Europe due to the spread of volcanic ash following the recent eruption under Iceland's Eyjafjallajoekull glacier. Volcanic eruptions eject large amounts of ash and trace gases such as sulphur dioxide into the atmosphere, often reaching the altitudes of scheduled flights. When flying through a volcanic ash cloud, ash particles enter the jet engines which can result in engine failure. The ash can also severely damage the material of the aircraft, clog its...

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...

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

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...
