Abstract:

Earthquake source theories of Haskell, Brune, Savage have been drawn upon to develop a description of an earthquake as a major slip accompanied by many smaller tensional and slip events. Natural explanations of several previously unexplained observations were found, such as Robustness of the M sub sm sub b discriminant P corner frequency higher than S corner frequency High-frequency PS amplitude ratio higher than previous theories predict Increase of complexity as a function of third moment Small m sub b relative to M sub s for transform faults. The theory predicts that M sub sm sub b populations of earthquakes and explosions will not converge at small magnitudes.
