Time-varying acceleration experienced by each facet. (a) Acceleration at facet 152 for different diffusivity values: K = 1000 m² s⁻¹ (Simulation 2, dotted), K = 2000 m² s⁻¹ (Simulation 1, solid), and K = 3000 m² s⁻¹ (Simulation 3, dashed). (b) Acceleration at facet 152 for different seismic efficiency values: η = 5.0 × 10⁻⁸ (Simulation 5, dotted), η = 1.0 × 10⁻⁷ (Simulation 1, solid), and η = 5.0 × 10⁻⁷ (Simulation 8, dashed). (c, d) Same as (a, b), but for facet 93. The horizontal dotted line represents the gravitational acceleration at each facet. The vertical dashed line marks t = 10 seconds, when the simulation ended and exponential decay extrapolation began.
