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...

Nature of mysterious hot spot revealed by "photogeology" By Diana Lutz, Washington University in St. Louis Analysis of new images of a curious "hot spot" on the far side of the Moon reveal it to be a small volcanic province created by the upwelling of silicic magma. The unusual location of the province and the surprising composition of the lava that formed it offer tantalizing clues to the Moon's thermal history. The hot spot is a concentration of a radioactive element thorium sitting between...

A central Indonesian volcano that first started erupting last Thursday shot hot ash and smoke into their air again on Sunday in what the Telegraph considers "it's most powerful eruption yet." Mount Lokon, which is located on northern Sulawesi island, is a 5,184 foot volcano that until this past week had not erupted since 1991. Thousands of people were forced to evacuate from a two-mile zone surrounding the volcano, which according to BBC News shot ash, sand, and rocks some 4,800 feet into the...

Lava on the Caribbean island of Hispaniola indicates deep rock is 1 billion years older than previously thought Earthquakes and volcanoes are known for their ability to transform Earth's surface, but new research in the Caribbean has found they can also move ancient Earth rock foundations more than 1,000 miles. Two University of Florida geologists are part of a team that found lavas on the Caribbean island of Hispaniola "“ home to Haiti and the Dominican Republic "” that suggest...

One of Iceland's most active and most feared volcanoes looks like is getting ready to erupt, with measurements indicating magma movement, according to Icelandic experts on Wednesday, raising fears of a new ash cloud disrupting air traffic in Europe and abroad. The Hekla volcano, dubbed by Icelanders in the Middle Ages as the "Gateway to Hell," has erupted some 20 times over the past 1000 years, with the most recent eruption occurring on February 26, 2000. Hekla is close to the ash-spewing...

Latest research into the age of volcanos in Western Victoria and South Australia has confirmed that the regions are overdue for an eruption, potentially affecting thousands of local residents. Using the latest dating techniques, scientists from the University of Melbourne's School of Earth Sciences and the Melbourne School of Engineering have calculated the ages of the small volcanoes in the regions and established the recurrence rate for eruptions as 2,000 years. With the last volcano...

The Puyehu volcano in southern Chile continues to erupt for a second day, spewing pumice and an ash cloud six miles high and three miles wide. Airline flights have been canceled in the region and more than 3,500 people stayed away from their homes near the volcano. Most of the residents in 22 settlements near the Puyehue-Cordon Caulle volcanic complex evacuated when the eruption began Saturday afternoon and were staying in government shelters or friends' homes. One group of 122 people was...

A 3-D model of a volcanic explosion, based on the 1980 eruption of Mount St. Helens in Washington state, may enhance our understanding of how some volcanic explosions occur and help identify of blast zones for potentially dangerous locations, according to an international team of volcanologists. "We took on the modeling of enormously complicated pyroclastic density currents, notably the classic, notorious May 1980 lateral blast that destroyed 500 square kilometers of forested terrain at Mount...

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

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

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...
