Subduction zone geometry offers a mega-earthquake risk indicator
Paris (SPX) Nov 29, 2016
Mega-earthquakes (with a magnitude greater than 8.5) mainly occur on subduction faults where one tectonic plate passes under another. But the probability of such earthquakes does not appear to be even across these zones. In a study published in the journal Science, researchers from the University of Oregon and Geoazur laboratory (CNRS/Universite Nice Sophia Antipolis/Observatoire de la Cote d'Azur/IRD) show that mega-earthquakes mostly occur on the flattest subduction zones. Thus, the Philippines, ... read more
