    • Before the triggering of the discharge, the fault system is in equilibrium because the resolved shear traction along the fault is balanced by the static friction strength. After triggering, the expansion of the high-pressure plasma at the simulated hypocenter creates a pressure pulse that releases the local normal pressure of the interface, thus dropping the level of frictional resistance. The resultant net driving force then initiates bilateral slip along the fault. The slip and slip rate reduce the coefficient of friction (slip and/or slip rate weakening) and hence, for a large enough inclination angle α, the rupture is able to continue. Thus, simulated earthquakes are triggered in the laboratory.
