BERKELEY, Calif. (KTVU) - A magnitude 7.0 earthquake along the Hayward Fault could kill as many as 800 people and injure 18,000, according to results of a new research released Wednesday. The U.S. Geological Survey, citing findings from a simulated tremor with an epicenter in Oakland, said the ...

The two Viking landers on Mars both carried seismometers, though one failed and the other sent no reliable signals. Ambitious efforts since then to put multiple seismic stations on Mars have sputtered. But the geophysicists kept pushing, Banerdt says. “I've been getting up at meetings and berating people ...

There was an earthquake north of Mont Laurier on Tuesday evening, and while some people reported feeling it, there was no damage. The earthquake happened about 15 kilometres north of the town at 6:59 p.m. Tuesday, said Earthquakes Canada. This region is part of what geophysicists call the West ...

Founded in 1989, terratec geophysical services has a team of 35 geophysicists and geologists who are fluent in a wide variety of languages, including English, German, French, Spanish, Russian and Arabic. We have bases in Germany, Bulgaria, Mali, Namibia and South Africa, as well as representatives in Austria, Sweden ...

An international team of geophysicists has discovered two hypersaline lakes beneath the Devon Ice Cap, one of the largest ice caps in the Canadian Arctic. A cold and windy spring night on the vast landscape of the Devon Ice Cap where two subglacial lakes are lurking 1,805 to 2,460 feet (550-750 m) ...

“If this works, it's fantastic.” Before there could be any chance at a payoff, however, the geophysicists gathered in France needed help from their farmer host. The generator they'd brought with them from Grenoble refused to start. Without it, they couldn't power R2-D2, and without the ground-shaking device, ...

West Texas is facing a reckoning: After decades of extracting countless barrels of oil and quantities of natural gas from the Permian Basin, an area about the size of the United Kingdom, the landscape is starting to warp and sink in drastic ways, threatening infrastructure and making the area increasingly ...

Radar satellite images show significant movement of the ground across a 4000-square-mile area—in one place as much as 40 inches over the past two-and-a-half years, say the geophysicists. "The ground movement we're seeing is not normal. The ground doesn't typically do this without some cause," said ...

A report released Thursday by geophysicists at Southern Methodist University says a 4,000-square-mile area near the "Wink Sinks" is showing signs of alarming instability. “The ground movement we're seeing is not normal. The ground doesn't typically do this without some cause,” SMU geophysicist Zhong ...

A team of geophysicists at the University of California, Berkeley, proposes that Martian oceans originated several hundred million years earlier than thought, as the Solar System's largest volcanic system — called Tharsis — formed, and that greenhouse gases enabled the oceans. The team's theory predicts ...

A new scenario seeking to explain how Mars' putative oceans came and went over the last 4 billion years implies that the oceans formed several hundred million years earlier and were not as deep as once thought. The proposal by geophysicists at the University of California, Berkeley, links the existence of ...

Scientists have for the first time captured the cracking sound of volcanic thunder – a feat many considered impossible. An ash cloud rising from a volcano can contain lighting, which observers previously said produced an eerie popping sound. But geophysicists have previously been unable to record the ...

Geophysicists propose that the oceans originated several hundred million years earlier than thought, as the volcanic province Tharsis formed, and that greenhouse gases enabled the oceans. The theory predicts smaller oceans, more in line with estimates of water underground and at the poles today.

And even though geophysicists are beginning to better understand what spots might be vulnerable to earthquakes, predictions are never fully certain. Regulations the Kansas Corporation Commission uses to evaluate new well applications don't take into account the likelihood of it causing an earthquake ...

An erupting volcano produces massive, rumbling sounds but scientists proved that volcanic thunder, a previously undocumented phenomenon, is real. The thunderclaps that follow a volcanic lightning can detect an eruptive activity. Geophysicists recorded sounds from the Bogoslof volcano. The volcano ...

Geophysicists are able to measure the rotational speed of Earth extremely precisely, calculating slight variations on the order of milliseconds. Now, scientists believe a slowdown of the Earth's rotation is the link to an observed cyclical increase in earthquakes. According to the couple-of-year old World Risk ...

Barrato and his colleagues on the communications side of the project are planning a pavillion that will create a private space for the geophysicists, engineers, and archaeologists to do their work, as well as communicate the story of the lost column to the public. To some extent, discovering the column itself ...

A team of geophysicists and archaeologists excavated ancient clay remnants dating back to the Iron Ages, when people performed ritual cleansings of their villages by burning down huts and grain bins. “When you burn clay at very high temperatures, you actually stabilize the magnetic minerals, and when ...

Seismologists who interpret high velocities of compressional waves compared with those of shear waves (high Vp/Vs ratios) as indicators of high pore pressures, oil explorers who recognize oil and gas zones in tomographic images, and geophysicists identifying high permeability and water content from ...

Climatologists are often asked, “Is climate change making hurricanes stronger?” but they can't give a definitive answer because the global hurricane record only goes back to the dawn of the satellite era. But now, an intersection of disciplines — seismology, atmospheric sciences and oceanography ...

According to geophysicists with the United States Geological Survey (USGS), the past fortnight has seen Yellowstone supervolcano shaken by a swarm of over 200 earthquakes since February 8, accompanied by innumerable smaller tremors too faint to accurately record. Despite how alarming this ...

Until about 20 years ago, geophysicists dismissed this low-intensity rumbling as noise, Gualtieri said. "What is noise? Noise is a signal we don't understand," said Pascale, who is also an associate research scientist at the National and Oceanic and Atmospheric Administration's Geophysical Fluid Dynamics ...

... there are at least 17 forms of water ice, and two proposed forms of super-cooled liquid water. New work from Carnegie high-pressure geophysicists Chuanlong Lin, Jesse Smith, Stanislav Sinogeikin, and Guoyin Shen found evidence of the long-theorized, difficult-to-see low-density liquid phase of water.

Geophysicists have obtained detailed three-dimensional images of a dangerous megathrust fault west of Costa Rica where two plates of the Earth's crust collide. The images reveal features of the fault surface, including long grooves or corrugations, that may determine how the fault will slip in an earthquake ...

A map created by Stanford geophysicists can help predict which parts of West Texas and New Mexico may be at risk of fracking-induced earthquakes. ... Stanford geophysicists have developed a detailed map of the stresses that act in the Earth throughout the Permian Basin in West Texas and southeastern ...

Rumblings of volcanic thunder have been recorded for the first time by geophysicists who monitored a series of violent eruptions on an island in the northern Pacific Ocean last year. Volcanic lightning, very, very frightening. Read more. The thunderclaps were created by lightning in the towering plumes of ...
