Seismologists introduce new measure of earthquake ruptures

A team of seismologists has developed a new measurement of seismic energy release that can be applied to large earthquakes. Called the Radiated Energy Enhancement Factor (REEF), it provides a measure of earthquake rupture ...

Are the Japanese and Ecuador earthquakes related?

A magnitude 6.5 earthquake struck Japan on Friday, causing widespread injuries and property damage. Then on Saturday evening, a magnitude 7.8 earthquake hit Ecuador on the other side of the Pacific, collapsing buildings and ...

Great earthquakes, water under pressure, high risk

The largest earthquakes occur where oceanic plates move beneath continents. Obviously, water trapped in the boundary between both plates has a dominant influence on the earthquake rupture process. Analyzing the great Chile ...

Solar splashdown

(Phys.org) —On June 7, 2011, our Sun erupted, blasting tons of hot plasma into space. Some of that plasma splashed back down onto the Sun's surface, sparking bright flashes of ultraviolet light. This dramatic event may ...

Researchers build better earthquake simulator

(Phys.org)—Traditional earthquake simulators have generally functioned by pressing two pieces of rock material together at high pressure until they reach a breaking point, resulting in something similar to the sticking ...
