Superquakes, supercycles, and global earthquake clustering: Recent research and recent quakes reveal surprises in major fault systems

A number of recent big earthquakes around the world have humbled many earthquake researchers. The March 2011 magnitude-9 superquake off Tohoku, Japan, and the December 2004 magnitude-9-plus temblor off Sumatra were both far larger than what scientists expected those fault systems to produce. Based on these quakes, and on recent research that contradicts long-held paradigms, it is becoming clear that the types and sizes of large earthquakes that a given fault system is capable of producing remain poorly known for most major fault systems.
