Giant earthquakes: not as random as thought

By analyzing sediment cores from Chilean lakes, an international team of scientists discovered that giant earthquakes reoccur with relatively regular intervals. When also taking into account smaller earthquakes, the repeat ...

Fault curvature may control where big quakes occur

Major earthquakes - magnitude 8.5 and stronger—occur where faults are mostly flat, say University of Oregon and French geologists. Curvier faults, they report in the journal Science, are less likely to experience earthquakes ...

Global map to predict giant earthquakes

A team of international researchers, led by Monash University's Associate Professor Wouter Schellart, have developed a new global map of subduction zones, illustrating which ones are predicted to be capable of generating ...

Are we living in an age of giant quakes?

Searching for patterns in the occurrence of large magnitude earthquakes after a succession of large tremors -- surpassed by the recent magnitude-9.0 quake in Japan -- has researchers wondering if the amount of big quakes ...
