Abstract:

Numerical results for stress and deformation fields have been obtained from models which portray the primordial mechanical non-uniformities of the Earth in terms of Maxwellian materials for the limiting cases of very long relaxation times. Calculations were based on these fields as produced by a primary tectonic and seismic motivating force originating from the rotation of the Earth, the Earths inelasticity, a Maxwellian upper mantle, and structural non-uniformities of the Earth, with application of the Principle of Maximum Uniformity. Results for first and second order non-uniformities indicate that this force produces stress fields of sufficient magnitude and configuration along prominent geological features such as the San Andreas Fault, Techeng- Lukian Fault in China, Aleutian Trench and Volcanic Arc, and the Mid-Atlantic Ridge to activate and sustain the tectonic and seismic activity of these regions.
