We start with a presentation relativelysimple concept spontaneous rupture propagation fault surface basicmodel source tectonic earthquake. Basic concepts - slip, slip rate, total trac-tion, traction variation, frictional strength faulting are deflned.The most general form constitutive law friction given brie°ycharacterized. continue stress-strain relation, equation ofmotion, local energy conservation law, strain function assumingstandard natural state in continuum mechanics characterized by zerostress strain. Then we present generalization these relations forthe case nonzero initial stress but zero strain.Such convenient consider just prior Wecontinue concise summary four models seismoactive faultand earthquake (fracture) Gri–th’s, Irwin-Orowan’s, breakdown-zone andflnite-thickness model.
