One referred to a recent scientific article and WSJ recap on whether large, distant earthquakes were related causally and temporally. A student had in fact recently asked me whether she should study in Berkeley this summer in the wake of the Japan earthquake. The Nature Geoscience paper, Absence of remotely triggered large earthquakes beyond the mainshock region, by Tom Parsons Aaron A. Velasco, concluded that "the regional hazard of larger earthquakes is increased after a mainshock, but the global hazard is not."
This paper and related research were summarized in the Wall Street Journal, by Gautam Naik.
