Seismic evidence for megathrust fault-valve behavior during episodic tremor and slip

Fault slip behavior during episodic tremor and slow slip (ETS) events, which occur at the deep extension of subduction zone megathrust faults, is believed to be related to cyclic fluid processes that necessitate fluctuations in pore fluid pressures. …

UO Geophysics group paper in Science Advances

Our group published a new paper in Science Advances that reports seismic observations consistent with a fault-valve model for episodic tremor and slip events in northern Cascadia.
