PARIS (AFP) - Recent massive volcanoes have risen from the ocean floor deep under the Arctic ice cap, spewing plumes of fragmented magma into the sea, scientists who filmed the aftermath reported Wednesday. The eruptions -- as big as the one that buried Pompei -- took place in 1999 along the Gakkel Ridge, an underwater mountain chain snaking 1,800 kilometres (1,100 miles) from the northern tip of Greenland to Siberia. Scientists suspected even at the time that a simultaneous series of earthquakes were linked to these volcanic spasms. But when a team led of scientists led by Robert Sohn of...

Dec 2, 2009 — Field geologists have revisited a site Darwin visited on the voyage of the Beagle, and found that he incorrectly interpreted what he found.  A large field of erratic boulders in Tierra del Fuego that have become known as “Darwin’s Boulders” were deposited by a completely different process than he thought.  The modern team, publishing in the Geological Society of America’s December issue of the GSA Today,1 noted that “Darwin’s thinking was profoundly influenced by Lyell’s obsession with large-scale, slow, vertical movements of the crust, especially as manifested in his theory of submergence and ice rafting to...

According to evolutionists, our moon is nearly as old as the Earth and, from the rate of unimpeded meteors hitting the moon's surface over billions of years, there should be many feet of lunar dust on the moon's surface.

A popular trail in Yellowstone National Park has been closed because of new geothermal hot spots that could endanger hikers. Park officials said Wednesday that geologists will use thermal imaging, temperature readings and a ground survey to examine hot spots on the Clear Lake Trail.

Sierra Nevada Rose To Current Height Earlier Than Thought, Say GeologistsGeologists studying deposits of volcanic glass in the western United States have found that the central Sierra Nevada largely attained its present elevation 12 million years ago, roughly 8 or 9 million years earlier than commonly thought. (Credit: iStockphoto/Ken Babione) ScienceDaily (Apr. 26, 2008) — Geologists studying deposits of volcanic glass in the western United States have found that the central Sierra Nevada largely attained its present elevation 12 million years ago, roughly 8 or 9 million years earlier than commonly thought. The finding has implications not only for understanding...

An enormous underwater landslide 60,000 years ago produced the longest flow of sand and mud yet found on Earth. The landslide off the coast of north-west Africa dumped 225 billion metric tonnes of sediment into the ocean in a matter of hours or days. The flow travelled 1,500km (932 miles) - the distance from London to Rome - before depositing its sediment. The work, by a British team of researchers has been published in the academic journal Nature. The massive surge put down the same amount of sediment that comes out of all the world's rivers combined over a period...

Dating a massive undersea slide Sid Perkins From San Francisco, at a meeting of the American Geophysical Union Pieces of moss buried in debris deposits along the Norwegian coast have enabled geologists to better peg the date of an ancient tsunami and the immense underwater landslide that triggered it. Carbon dating of the newly unearthed moss suggests that the landslide occurred about 8,100 years ago. Sometime after the end of the last ice age, the largest landslide known to geologists took place off the coast of Norway. Called the Storegga slide, this slump of seafloor sediments included about 3,000 cubic...

Persepolis architects were geologists, too Tehran Times Culture Desk TEHRAN – Recent geological studies at the Persepolis historical site indicate that Achaemenid era architects used their unique knowledge of geology and mines in the construction of Persepolis, the Persian service of CHN reported on Thursday. The experts were well aware of the science of geology and were keen to discover underground sources of water, geologist Azam Zare said. The studies show that the Achaemenid experts had acquired specialized knowledge and technology, but it is unclear how they mastered these skills, she added. “The studies of the geological team at Persepolis...

EARTH'S natural radioactivity has been measured for the first time. The measurement will help geologists find out to what extent nuclear decay is responsible for the immense quantity of heat generated by Earth. Our planet's heat output drives the convection currents that churn liquid iron in the outer core, giving rise to Earth's magnetic field. Just where this heat comes from is a big question. Measurements of the temperature gradients across rocks in mines and boreholes have led geologists to estimate that the planet is internally generating between 30 and 44 terawatts of heat. Some of this heat comes from...

<p>YELLOWSTONE NATIONAL PARK, Wyo. -- Steam wafted over Hank Heasler as he stood on a boardwalk and watched water from Steamboat Geyser shoot into the air with an attention-grabbing "WHOOSH!"</p> <p>"This could be it," the park geologist said excitedly, squinting against the morning sun at the impressive spray. But Heasler had no better idea than the tourists around him as to when the world's tallest geyser would next erupt.</p>

LOS ANGELES - A recently mapped, still-active fault line that snakes beneath downtown Los Angeles is capable of generating major earthquakes (news - web sites), but only about once every 2,000 years, according to a new study. At least four earthquakes of estimated magnitudes 7.2 to 7.5 have struck over the last 11,000 years on the Puente Hills fault, which was first mapped just four years ago. A segment of the fault last ruptured in 1987 with a magnitude-6 earthquake (news - web sites). The study is the first to show how often and with how much punch large quakes...

Geologists show Homer got it rightTrojan geography in Homer's Iliad matches sediment record of Dardanelles coastline. 29 January 2003 PHILIP BALL The ruins of Troy now perch on the edge of a plateau overlooking a river flood plain. © Uni. of Oxford Homer knew his geography, say US researchers. The ancient Greek writer's description of the war fought around Troy is consistent with a new reconstruction of the way the region looked about three millennia ago1. In his Iliad, Homer recounts how the city of Troy was besieged and finally conquered by the army of the Spartan king Menelaus, who...

The team will also explore how the disappearance of the land bridge may have affected that region's climate.
