Episodicity and Migration of Low Frequency Earthquakes modeled with Fast Fluid Pressure Transients in the Permeable Subduction Interface

Abstract : • We model fluid pressure diffusion in a channel along the subduction interface in which the permeability varies through a valving mechanism • Tremor is generated as valves break open and interactions between valves through fluid pressure transients shape realistic event patterns • The input fluid flux in the fault controls seismic activity, opening possibilities to diagnose hydraulic conditions using LFE patterns
