Study proposes common mechanism for shallow and deep earthquakes

Earthquakes are labeled "shallow" if they occur at less than 50 kilometers depth. They are labeled "deep" if they occur at 300-700 kilometers depth. When slippage occurs during these earthquakes, the faults weaken. How this ...

Researchers find evidence of super-fast deep earthquake

As scientists learn more about earthquakes that rupture at fault zones near the planet's surface—and the mechanisms that trigger them—an even more intriguing earthquake mystery lies deeper in the planet.

Great Nepalese quake of 1255 points to Himalayan risk

A mega-quake in 1255 that wrecked the Nepalese capital, wiped out a third of the population of Kathmandu Valley and killed the country's monarch, King Abhaya Malla, was of a kind that may return to the Himalayas, seismologists ...

Smartphones as seismometers intrigue Berkeley researchers

(Phys.org)—Researchers at the Berkeley Seismological Laboratory want to table smartphones as pocket-sized seismometers. The phones used as warning systems could make a life or death difference in the seconds one might have ...

Earthquakes generate big heat in super-small areas: study

Most earthquakes that are seen, heard, and felt around the world are caused by fast slip on faults. While the earthquake rupture itself can travel on a fault as fast as the speed of sound or better, the fault surfaces behind ...
