Flowing lava can carve or build paths very much like the riverbeds and canyons etched by water, and this probably explains at least one of the meandering channels on the surface of Mars. These results were presented on March 4, 2010 at the 41st Lunar and Planetary Science Conference by Jacob Bleacher at NASA's Goddard Space Flight Center, Greenbelt, Md. Whether channels on Mars were formed by water or by lava has been debated for years, and the outcome is thought to influence the likelihood...

On January 2, Mount Nyamulagira in the Democratic Republic of Congo erupted, spewing lava from its southern flank and raising concerns that the 100 000 people in the town of Sake could be under threat. Fears were also triggered in Goma as rumors circulated that an eruption was imminent at the nearby Nyiragongo volcano, which devastated the city in 2002. Following the eruption, scientists and local authorities have been using a long series of space images from ESA's Envisat, together with...

Spanish and French researchers have defined the age, location, size and geochemistry of the volcanoes of Gran Canaria during the Holocene, 11,000 years ago, in order to draw up a map of volcanic hazards for the island. The research shows that the area of greatest volcanic activity is one of the most heavily populated areas in the north east of the island, which has suffered 24 eruptions over the period studied. The team of French and Spanish scientists led by researchers from the University...

Power plants might pipe emissions under seabed Scientists say buried volcanic rocks along the heavily populated coasts of New York, New Jersey and New England, as well as further south, might be ideal reservoirs to lock away carbon dioxide emitted by power plants and other industrial sources. A study this week in the Proceedings of the National Academy of Sciences outlines formations on land as well as offshore, where scientists from Columbia University's Lamont-Doherty Earth Observatory say...

The Virunga National Park, home to 200 of the world's 720 mountain gorillas, is in the path of molten hot lava spewing from a volcano that has erupted in the eastern Democratic Republic of Congo. The park is also home to elephants, hippos and buffalo, along with a range of reptiles and birds. It's said lava from Mount Nyamuragira began picking up speed when it hit the steep ground near the national park. The volcano is 22 kilometers from the provincial capital Goma, which it last threatened...

YARMOUTH PORT, Mass., Dec. 29 /PRNewswire-USNewswire/ -- As residents of the Philippines brace for the imminent eruption of the Mayon volcano, officials have asked the International Fund for Animal Welfare (IFAW) to help evacuate affected animals. At this time, there are an estimated 2,000 head of water buffalo, 1,000 head of cattle, 5,500 pigs, 19,000 poultry, and 4,600 dogs living near the volcano and in need of immediate evacuation. For the last two weeks, the 8,070-foot Mayon volcano...

Despite the growing infrequency of tremors in the Philippines' active Mayon volcano, experts say that a swell of magma is building up beneath it that could eventually be released in a powerful and dangerous eruption. State volcanologist Ed Laguerta has cautioned that residents of the surrounding areas should not be lured into returning home by the volcano's apparent return to dormancy.  An eruption could occur at any moment and could potentially devastate the countryside around it....

Government officials in the Philippines say that Mayon volcano could erupt violently within days, following a week of spectacular flows of lava and increasing volcanic quakes, The Associated Press reported. Some 3,000 villagers are still lingering around the volcano even after government warnings to leave the danger zone. Gov. Joey Salceda said tens of thousands of people have already been evacuated from the foothills of Mayon, which on Monday emitted lava fountains, powerful booming noises,...

Scientists have unveiled video footage of the deepest underwater volcanic eruption, at a site where sweltering 2,500-degree lava explodes into cold water nearly a mile below the ocean surface. Bob Embley, a marine geologist at NOAA's Pacific Marine Environmental Laboratory in Newport, Oregon, said, "It was very exciting. We've never seen anything like that on the ocean floor." The West Mata volcano, six miles long and four miles wide, rises one mile from the sea floor and sits 4,000 feet...

Like an angry dog, a volcano growls before it bites, shaking the ground and getting "noisy" before erupting. This activity gives scientists an opportunity to study the tumult beneath a volcano and may help them improve the accuracy of eruption forecasts, according to Emily Brodsky, an associate professor of Earth and planetary sciences at the University of California, Santa Cruz. Brodsky presented recent findings on pre-eruption earthquakes on Wednesday, December 16, at the fall meeting 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
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...

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...
