Abstract: We quantify sliding stability and rupture styles for a horizontal interface between an elastic layer and stiffer elastic half-space with a free surface on top and rate-and-state friction on the interface. Specific motivation (and model parameters) comes from quasi-periodic slow slip events on the Whillans Ice Plain in West Antarctica. We quantify the influence of layer thickness on sliding stability, specifically whether steady loading of the system produces steady sliding or sequences of stick-slip events. This dataset contains input files from different parts of parameter space to demonstrate different styles of slip (steady sliding, slow slip sequences, and fast slip sequences).
