ARTIFICIAL STIMULATION OF EARTHQUAKES

Abstract

A discussion of a two dimensional elastic dynamics technique developed to simulate seismic disturbances as a result of various input or grid created disturbances. The method exhibits calculational stability over other techniques using quadrilateral grids. A quieter mesh results from which more information can be extracted from the calculation. The results section discusses simulations of brittle fractures propagating through the isotropic elastic media. Emphasis is placed on the fact that the simulated cracks, using simple failure criteria, propagate at speeds greater than normally predicted in the literature. These simulations exhibit that the description of dynamic failure is more complex than those used.
