| Abstract: | This paper holds that, the applications of nonlinear scientific methods to rock rupture and earthquake phenomena should be in accordance with the characteristics of the processes themselves of these phenomena. That is a). the fractal geometric characteristics of crack systems; b). the self-organization mechanisms in the evolution processes; c). the chaotic dynamical behavior of earthquake faulting. Tracing the evolution processes of earthquakes as well as rock rupture (including formation of crack systems, deformation localization and formation of faults, faulting and finally stress relaxation), this paper sruveys the application of nonlinear scientific methods (fractal geometry, chaotic dynamics, and self-organization synergetics)to earthquake as well as rock rupture phenomena, proposes the universal characteristics and mechanisms of the corresponding processes obtained by using the nonlinear scientific methods, and argues on problems that are still controversy and need further investigating. |
