Coupling fraction model to interpret the motion of non-fully coupled strike-slip faults

Despite coupling fractions being extensively used in the interseismic period, coexistence of locking and creeping mechanisms correlation between fraction depth remain poorly understood because lack a physical model. To overcome these limitations, this study, we propose model for interpreting motion non-fully coupled strike-slip faults based on classic two-dimensional fault superposition principle. The was constructed using numerous tiny, alternating segments. deformation produced by is same as that fault, except scale factor. definition can be perfectly integrated. Based model, put forward varying decoupled with which considers depth-dependent fraction. two models provide deep insights into characteristics quasi-arctangent curves local macroscopic period.
