According to current mantle-plume theory, Anderson explains, heat from Earth's core somehow generates narrow jets of hot magma that gush through the mantle and to the surface. The jets act as pipes that transfer heat from the core, and how exactly t
The seamount is about two-thirds of a mile high (1.1 kilometers), researchers said. Seamounts, rocky leftovers from extinct, underwater volcanoes, are found on ocean floors around the world. The newly discovered seamount is about 186 miles (300 km) s
Utilizing a comprehensive array of remote sensing technology and non-invasive geophysical survey equipment, researchers working on the site of Stonehenge in Wiltshire, England have revealed hundreds of previously unknown features buried deep beneath
Between North Carolina's Cape Hatteras and Massachusetts' Georges Bank, 570 methane seepscluster in about eight regions, according to sonar and video gathered by the National Oceanographic and Atmospheric Administration ship Okeanos Explorer betwee
Despite being one of the poorest nations in the world, Afghanistan may be sitting on one of the richest troves of minerals in the world, valued at nearly $1 trillion, according to U.S. scientists.
The last confirmed eruption from Bar?arbunga was back in 1910 (Author?s note: As Jon Frimann in the comments below correctly points out, this 1910 eruption was from Loki-F?grufj?ll, which is near Bar?arbunga but not the same edifice. However, these t
This incredible series of events took place south of the Russian peninsula Kamchatka and were witnessed by Dutch pilot JPC van Heijst and his co-pilot as they flew their Boeing 747 to Alaska. While there's no official explanation for the event th
Scripps paleooceanographer Richard Norris describes the mystery of sliding rocks in Death Valley.
A large earthquake rolled through California's northern Bay Area early Sunday, damaging some buildings, knocking out power to thousands and sending residents running out of their homes in the darkness.
This event is somewhat analogous to a antural mudslide. Afterwards, the debris is cleaned up and people somehow get back on with their lives. In those mudslides debris has been moved sometimes settling into nearby streams, rivers and lakes. ?The mate
Mount Rainier and Mount St. Helens are two of scores of snow-capped volcanoes that march up the West Coast, from Northern California to British Columbia, Canada. If Mount Rainier erupts, its glaciers could melt and trigger lethal mudflows called laha
The space rock is a 470-million-year-old fossil meteorite first spotted three years ago by workers at Sweden's Thorsberg quarry, where stonecutters have an expert eye for extraterrestrial objects. Quarriers have plucked 101 fossil meteorites from th
A mixture of water, salt and gas may have ignited an underground explosion. Another possibility is that the gas pocket may simply have built up enough pressure to pop like a Champagne cork, she said.
Ready to rumble? The world's largest volcano—Hawaii's Mauna Loa—appears to be stirring back to life after a relatively quiet 30 years, geologists say.
They found signs of wet ringwoodite in the transition zone 700 kilometres down, which divides the upper and lower regions of the mantle. At that depth, the pressures and temperatures are just right to squeeze the water out of the ringwoodite. "It's
Earth's most abundant mineral lies deep in the planet's interior, sealed off from human eyes.
A new study by researchers at the University of Texas, Austin found that the West Antarctic Ice Sheet is collapsing due to geothermal heat, not man-made global warming.
For Los Angeles, California, May 2014 was a month of heightened seismic activity, boasting five earthquakes that measured greater than 4.0 on the Richter scale.
An Alaska volcano that has been spewing ash and lava for years began erupting with new intensity this week, pushing a plume of smoke and ash as high as 24,000 feet (7,315 meters) and prompting scientists to issue their highest volcanic alert in five
In 50 years, no earthquake since has matched the power of the March 27, 1964, Great Alaska earthquake. Now ranked a magnitude 9.2, the second-largest ever recorded, the earthquake radically transformed the young state. Important coastal ports, roads
The bacteria is incredibly resistant to this toxic element. In fact, it's 25 times stronger than previously thought. The researchers' compact factory—which they named The Great Work of the Metal Lover—holds the bacteria as they feed it the gold chl
The roughly 8,300-foot volcano erupted in an explosion of hot ash and gas on May 18, 1980, spewing debris over some 230 square miles and causing more than a billion dollars in property damage. Entire forests were crushed and river systems altered in
] Although scientists had previously hypothesized enormous ancient impacts, much greater than the one that may have eliminated the dinosaurs 65 million years ago, now a new study reveals the power and scale of a cataclysmic event some 3.26 billion ye
Bercovici began with the idea that, back when Earth was just a ball of hot goo, certain parts of the surface would become cooler than others and sink. These areas were called downwellings. "You can see this happen in a cup of coffee or soup," he s
Magma levels are slowly rebuilding inside Mount St. Helens, a volcano in Washington state that erupted in 1980 and killed 57 people, although there was no sign of an impending eruption, U.S. scientists said.
A powerful magnitude 7.2 earthquake has struck Mexico's capital and Pacific coast, shaking buildings, shattering windows and sending residents fleeing into the streets.
Most Americans don’t realize this, but there are some very powerful volcanoes in Russia as well. On the Kamchatka peninsula, which is located on the east coast of Russia, a large volcano has belched a column of ash 6 km into the air… Volcano Shiv
"Olivine shows only defects along two directions, not three," Cordier said. "This is not enough for achieving a general deformation. However, olivine-rich natural rocks show pervasive evidence suggesting that olivine deforms very easily in the m
2006 - "Geologists think there could be billions of gallons of oil under Nevada's deserts" ...
Great Subduction Zone earthquakes are the largest earthquakes in the world, and can exceed magnitude 9.0. Earthquake size is proportional to fault area, and the Cascadia Subduction Zone is a very long sloping fault that stretches from mid-Vancouver I
