Short summary
A spring-block model is used to determine an upper limit of slow-earthquake zones through study of self-oscillatory behavior with the Hopf bifurcation mechanism. What is the role of fluids in the mechanism of energy dissipation? Are the variations in oscillatory behavior (in the transition zone) due to external forces? What are the limits of parameters for this to occur? The proposed limit makes a difference to oscillatory behavior. Oscillation frequency, L, and fluids are related to results.
