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.

The geologists and geophysicists use it to look for hydrocarbons. For exploring substances lying beneath the Earth's surface at places where the geology is quite complex, the Anisotropic RTM technology is very useful. Up until recently, the anisotropic RTM was applied mainly in subsalt environments or ...
Rather than a “worrisome” sign of a supervolcano eruption, geophysicists like Mike Poland and Jamie Farrell see the seismic unrest east of West Yellowstone as a learning opportunity. The duo wrote of that potential in a recent blog post on the USGS's Yellowstone Volcano Observatory website. “It is during ...
