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...

Two French scientists are travelling to one of the remotest places on Earth, the Kamchatka peninsula, to piece together the complex life story of two volcanoes. Kamchatka is one of the most volcanically active places on Earth. It is part of the Ring of Fire "“ intermittent chains of volcanoes that encircle the Pacific Ocean. Over at least the last 6 million years, Kamchatka has experienced more explosive eruptions than any place on Earth. Historically, the level of activity has made it...

While the ongoing eruption of a volcano in Iceland has caused havoc for local farmers and travelers throughout Europe, a possible eruption of a much stronger volcano at the Yellowstone National Park would be potentially devastating, a representative from the U.S. Geological Survey (USGS) told reporters on Monday. "The impact would be severe," Bill Burton, a volcanologist with the agency, told the AFP news agency. Fortunately, he adds, "The next major eruption for Yellowstone, if you have a...

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...

Scientists have found the "Rosetta Stone" of supervolcanoes, those giant pockmarks in the Earth's surface produced by rare and massive explosive eruptions that rank among nature's most violent events. The eruptions produce devastation on a regional scale "” and possibly trigger climatic and environmental effects at a global scale. A fossil supervolcano has been discovered in the Italian Alps' Sesia Valley by a team led by James E. Quick, a geology professor at Southern Methodist...

U.S. scientists say the 15-mile-high Olympus Mons volcano on Mars might answer the question of whether that planet ever had, or still has, water. Rice University Assistant Professor Patrick McGovern and Associate Professor Julia Morgan used an algorithm to analyze the volcano's structure. They determined that only the presence of ancient clay sediments could account for the volcano's asymmetric shape -- and the presence of sediment indicates water was, or is, involved. Olympus Mons slopes...

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...

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...
