Earthquake fragmentation and slip processes: spin and shear-twist wave mosaic

We followour former considerations on rotational processes and emission of rotation and shear-twist waves as occurring in earthquake source zones. A concise presentation of the motion and constitutive relations is given for each type of the four fundamental point deformations: displacements, rotations, point stretch/squeeze, and string-string point deformations (shear nuclei). We apply the Asymmetric Continuum Theory to the micro-fracture processes in an earthquake source zone: the fragmentation and slip processes are described by the linear and rotational transport fields incorporated in the motion equations. The advanced non-linear micro-fracture processes under high load are discussed.
