Image 1 - NASA: No Evidence Of 2012 Supervolcano
2011-11-15 11:46:51

NASA said on Tuesday that there is no evidence of a massive supervolcano erupting in 2012, despite what some may believe. A supervolcano refers to an explosive volcanic eruption that eject about ten thousand times the quantity of magma and ash that Mount St. Helens expelled in 1980. NASA said Earth's surface has preserved clues of many massive supervolcanoes through hollowed-out calderas-craters that can be as big as 60 miles across after a volcano collapses from emptying out its entire...

Scientists Find Possible Trigger For Volcanic 'Super-eruptions'
2011-10-13 03:35:17

The "super-eruption" of a major volcanic system occurs about every 100,000 years and is considered one of the most catastrophic natural events on Earth, yet scientists have long been unsure about what triggers these violent explosions. However, a new model presented this week by researchers at Oregon State University points to a combination of temperature influence and the geometrical configuration of the magma chamber as a potential cause for these super-eruptions. Results of the...

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...

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...

The composition of a vast plume of hot rock and briny fluid 200 miles beneath Yellowstone National Park's surface has been mapped, a soon-to-be published study says. Researchers are able to receive a clear picture of the type of material that activates Yellowstone's volcanic features through these "geoelectric" images of the plume, says study co-author Robert B. Smith, professor emeritus at the University of Utah and coordinating scientist of the Yellowstone Volcano Observatory. "This is the...

The Kilauea volcano that recently erupted on the Big Island of Hawaii will be the target for a NASA study to help scientists better understand processes occurring under Earth's surface. A NASA Gulfstream-III aircraft equipped with a synthetic aperture radar developed by NASA's Jet Propulsion Laboratory in Pasadena, Calif., departed on Sunday, April 3, from the Dryden Aircraft Operations Facility in Palmdale, Calif., to the Big Island for a nine-day mission. The Uninhabited Aerial Vehicle...

Geologists in Iceland discovered a big surprise while drilling an exploratory geothermal well in 2009 in the Krafla volcano:  the presence of underground lava, known as magma, flowing into the well at a depth of 6,900 feet (2.1 kilometers). "To the best of our knowledge, only one previous instance has been documented of magma flowing into a geothermal well while drilling," said Wilfred Elders, a geologist at the University of California, Riverside, who led the research team. Elders and...

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...

Lake Toba

Lake Toba, also known as Toba, is a supervolcano and lake that is located in Indonesia on the island of Sumatra. The volcano reaches an elevation of 2,953 feet and the lake stretches across an area of sixty-two miles and is the largest volcanic lake on earth. Toba holds a caldera complex that is comprised of four volcanic craters that overlap each other, the youngest of which is noted as the largest Quaternary caldera. Visible features within the lake include three craters, four cones, and...

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...
