Cascading earthquakes and the theory of global rupture

• Terrence Aym
What if a super-quake set off other super-quakes around the world in a cascading cacophony of catastrophe? Since the mega-thrust quake that struck northeastern Japan during March 2011, that question is on the lips of many. Some researchers believe that non-local earthquake cascades occur in clusters and point to graphs depicting energy release versus time. They argue that the charts don't lie and the numbers prove that historically most of the energy released by major earthquakes results in several very large quakes globally—a chain of destructive dominoes collapsing one upon the other.
