MEGA earthquakes may be more likely due to ‘stable’ zones, say researchers

MEGA earthquakes may be more likely due to ‘stable’ zones, say researchers

“Stable” zones could contribute to massive earthquakes, according to researchers from Caltech.

Larger earthquakes may be more likely due to so-called “stable” zones, according to researchers from California Institute of Technology (Caltech.)

Previous research has suggested that “stable” zones act as barriers to fast-slipping, shake-producing earthquake ruptures, but a new study by Caltech researchers and the Japan Agency for Marine-Earth Science and Technology suggests otherwise. Typically, “stable” zones, where fault segments slip slowly, aren’t thought to be capable of hosting rapid earthquake-producing slip. A new study, however, throws this theory out of the window.
