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.
