The effect of the interaction among heat, fluid pressure and inelastic pore creation on dynamic earthquake slip process is investigated. The diversity of dynamic earthquake slip can be explained by the single framework in a unified way, which includes three nondimensional parameters. In particular, two of them are found to govern the system behavior without fluid flow. Two qualitatively different slip behaviors, acceleration and spontaneous slip cessation, have been found and the function determining which case appears is derived analytically. The constitutive relationship between the frictional stress and the slip is also obtained. The least energy required to arrest the slip is related to the minimum value of the inelastic porosity change for the spontaneous slip cessation case.
