DYNAMICS OF THE CRUSTAL STRESS-STRAIN FIELD

Recent seismological observations indicate that the Earth's crust is a bundant in stress/strain waves in addition to ordinary seismic waves. I present an earthquake fault model based on the theological propertie s of the crust to address such crustal dynamics. This model is consist s of a uniform chain of blocks and springs basically similar with the Burridge and Knopoff (1967)[1] model but a simple ductile regime is in troduced. Simulations show existence of irregular deformation patterns and propagation of kink type waves that may account for real observat ions.
