WebThe theory of plate tectonics provides a basic framework for evaluating the potential for future great earthquakes to occur along major plate boundaries. Along most of the transform and convergent plate boundaries considered in this paper, the majority of seismic slip occurs during large earthquakes, i.e., those of magnitude 7 or greater. The concepts …

WebDec 10, 1991 · One of the earliest and clearest applications of the seismic gap theory to earthquake forecasting was by McCann et al. (1979), who postulated zones of high, medium, and low seismic potential around the Pacific rim. In the 10 years since, there have been over 40 large ( M ≥ 7.0) earthquakes, enough to test statistically the earlier forecast. WebThe seismic gap or seismic cycle hypothesis has been, and appears still to be, applied to California for predicting seismic hazard (see, for example, WGCEP, 2002). One cannot test the seismic cycle model in a region (e.g., California) because relevant earthquakes occur too infrequently. But the seismic gap hypothesis of McCann et al. [1979] and ... organoleptic usp
