Abstract

A stochastic framework is developed, in terms of the theory of homogeneous random functions, to estimate the seismic hazard associated with linearly extending seismic sources. The formulation is carried out in the space-time domain. An earthquake having at least a magnitude of m is assumed to occur whenever the total strain energy accumulated over the potential rupture plane exceeds the energy level corresponding to this magnitude, m. An alternative formulation, in which an earthquake is generated when the total shear force exceeds the total static friction force developed over the ruptured portion of the fault plane, is also described.
