(Phys.org) —A team of Chinese researchers along with representatives from the US and Japan have found that ground fractures along fault lines due to earthquakes appear to heal faster than previously thought. In their paper ...
Scientists have determined the temperature near the Earth's centre to be 6000 degrees Celsius, 1000 degrees hotter than in a previous experiment run 20 years ago. These measurements confirm geophysical models that the temperature ...

(Phys.org) —Seismologists from Columbia University in New York have developed a way to detect landslides using a combination of seismic data and data collected from satellite images. The technique can be used, the team ...
(Phys.org)—When an earthquake strikes, damage to buildings such as nuclear power stations can worsen the catastrophe. Researchers from France's Institut Fresnel and the French division of Menard, a ground-improvement specialist ...
