英文摘要: We study the physics of dynamically triggered tectonic tremor by applying a brittle-ductile friction model in which we conceptualize the tremor source as a rigid block subject to driving and frictional forces. To simulate dynamic triggering of tremor, we apply a stress perturbation that mimics the surface waves of remote earthquakes. The tectonic and wave perturbation stresses define a phase space that demonstrates that both the timing and amplitude of the dynamic perturbations control the fundamental characteristics of triggered tremor. Tremor can be triggered instantaneously or with a delayed onset if the dynamic perturbation significantly alters the frictional state of the tremor source. Key Points Dynamic triggering of tremor is simulated using a brittle-ductile friction model Triggering potential depends on both perturbation amplitude and tectonic stress Delayed-onset triggering of seismicity can occur due to nonlinear fault friction ©2013.
