Iceland's Basalt Pillars Not From Warring Trolls, As Folk Legend Has It
2014-02-04 13:18:11

[ Watch the Video: Trolls Not Responsible For Iceland's Basalt Pillars ] Lee Rannals for redOrbit.com - Your Universe Online Icelandic trolls are not responsible for shaping the basalt pillars found on the island, according to a study recently published in the Journal of Volcanology and Geothermal Research. Folklore says that mysterious basalt pillars found in Iceland were created by a pair of angry trolls who hurled rocks at one another. However, the new study says that these...

Potential Eruption In Iceland Could Pump Acid Into European Airspace

A modern recurrence of an extraordinary type of volcanic eruption in Iceland could inject large quantities of hazardous gases into North Atlantic and European flight corridors, potentially for months at a time, a new study suggests. Using computer simulations, researchers are investigating the likely atmospheric effects if a “flood lava” eruption took place in Iceland today. Flood lava eruptions, which stand out for the sheer amounts of lava and sulfurous gases they release and...

After lying dormant underneath a glacier since 2004, a volcano in Iceland began spewing steam, ash and smoke into the upper atmosphere on Sunday. Despite the impressive show, this eruption is less likely to endanger air traffic as a similar eruption last did last year. Closing the main airport in the country as a precaution, pilots were warned to steer clear of Iceland as areas close to the Grimsvotn (GREEMSH-votn) volcano were plunged into darkness. Scientists, however, explain that another...

The next Yellowstone eruption could be similar volcanic event Millions of years ago, volcanic eruptions in North America were more explosive and may have significantly affected the environment and the global climate. So scientists report in this week's issue of the journal Nature. The researchers found the remains--deposited in layers of rocks--of eruptions of volcanoes located on North America's northern high plains that spewed massive amounts of sulfate aerosols into the atmosphere 40...

On March 20, Iceland's Eyjafjallajokull volcano woke from its nearly 200-year slumber to change the way the world viewed volcanoes forever. Bringing almost all transatlantic air travel to a halt for the first time in modern history, this volcano reminded humanity of the powers these forces of nature contain "“ and of our relative inability to understand them. Associate Professor Huiming Bao of LSU's Department of Geology & Geophysics has published research in the journal Nature...

Although the Eyjafjoell volcano in Iceland has continued to erupt since April 14, it is spewing far less ash than last week when it caused new interruptions to flights throughout Europe, according to a geologist on Monday. The volcano was responsible for the massive shutdown in flights across Europe last month, the likes of which have not been seen since World War II. The shutdown affected more than 100,000 flights and eight million passengers over a week. Last Thursday, a secondary...

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...

For the first time, researchers have taken a detailed look at what lies beneath all of Iceland's volcanoes "“ and found a world far more complex than they ever imagined.  They mapped an elaborate maze of magma chambers - work that could one day help scientists better understand how earthquakes and volcanic eruptions occur in Iceland and elsewhere in the world. Knowing where magma chambers are located is a key first step to understanding the chemical composition of the molten rock...

Volcanic eruptions in high-latitudes can greatly alter climate and distant river flows, including the Nile, according to a recent study funded in part by NASA. Researchers found that Iceland's Laki volcanic event, a series of about ten eruptions from June 1783 through February 1784, led to unusual temperature and precipitation patterns, including a significant reduction in the amount of rain that fell over much of the area surrounding the Nile River and led to record low river levels. The...

NASA -- When a volcano erupts, it does more than just create an ash cloud that darkens and cools a region for a few days. Instead, the most dramatic effect is actually high above us, where spewed volcanic material is not quickly washed out by rain. If the volcanic eruption is strong enough it will inject material into the stratosphere, more than 10 miles above the Earth's surface. Here, tiny particles called aerosols form when the volcano's sulfur dioxide combines with water vapor. Despite...
