Mount Etna Begins 12th Eruption Of Year
2011-08-30 09:44:46

  Italy´s famed volcano Mt. Etna has erupted for the twelfth time this year, spewing lava and ash into the upper atmosphere, according to an Associated Press report. Italy´s Civil Protection Agency says the nation´s geophysics and volcanology institute on Monday registered increased explosive activity by Etna, eight days after the latest eruption began, spewing out a significant amount of ash in a southeast direction early in the day but that the eruption tapered off...

The 2010 ash cloud from Iceland's Eyjafjallajokull volcano that disrupted air travel in the UK and cost European businesses more than $2.6 billion was likely a once in a lifetime event, according to scientists, who have analyzed a record of past similar events stretching back into prehistory across northern Europe. Their analysis showed that past ash clouds like the one seen in 2010 occurred on an average of once every 56 years. A report of the findings has been published in the journal...

Sunken oceanic crust resurfaces from Earth's mantle after only 500 million years The recycling of the Earth's crust in volcanoes happens much faster than scientists have previously assumed. Rock of the oceanic crust, which sinks deep into the earth due to the movement of tectonic plates, reemerges through volcanic eruptions after around 500 million years. Researchers from the Max Planck Institute for Chemistry in Mainz obtained this result using volcanic rock samples. Previously, geologists...

US scientists from Oregon and New York, who have been monitoring the Axial Seamount, an undersea volcano located 250 miles off the Oregon coast, said on Tuesday that they have successfully predicted an eruption for the first time. The team of scientists forecast the eruption beginning about five years ago, predicting the volcano, which last erupted in 1998, would erupt again sometime before 2014. This marks the first successful prediction of eruption of an undersea volcano. During an...

On the remote, uninhabited Chuginadak Island in Alaska, a volcano has begun erupting, but poses little danger to people or aircraft, officials said Tuesday. The Cleveland volcano is erupting with a slow effusion of magma, forming a lava dome. It is not an explosive eruption that generates large ash plumes, explains John Power, the scientist-in-charge at the Alaska Volcano Observatory. "So far, it's just lava as far as we can tell from our satellite imagery and the people who have managed to...

Primary succession on the slopes University of Guam ecologist Thomas Marler recently mobilized efforts to characterize the vegetation that has recovered following the eruption of Mount Pinatubo, Philippines. "My interest was sparked by the paradox that this volcano's cataclysmic 1991 eruption was so powerful it changed global climate, yet after a full 15 years the biology of the recovering ecosystem had not been studied," said Marler. The void of research motivated the Guam ecologist to spend...

Lee Rannals for RedOrbit.com From just the first chapter, the genius of Clive Oppenheimer in the world of volcanology shines in his book "Eruptions That Shook The World."  This book is not for the faint at heart when it comes to literature, but obviously a book for one who is ambitious about learning. "In a way, what I wanted to do with the book was to imagine what the world would be like today if all the volcanoes had been switched off a few million years ago - how different would...

Mount Etna volcano on the island of Sicily erupted during the weekend, shooting flames 820-feet in the air and spewing lava down its slopes. Some are concerned about the effects the eruption will have on air travel, but the winds were blowing the ash away from the airport and no flights had been cancelled. According to the Italian Institute of Volcanology, the volcanic activity started on Saturday morning and continued through the day and overnight into Sunday. This is the fourth and the...

Geological history has periodically featured giant lava eruptions that coat large swaths of land or ocean floor with basaltic lava, which hardens into rock formations called flood basalt. New research from Matthew Jackson and Richard Carlson proposes that the remnants of six of the largest volcanic events of the past 250 million years contain traces of the ancient Earth's primitive mantle"”which existed before the largely differentiated mantle of today"”offering clues to the...

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

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...
