One of the high‐profile developments in seismology over the past decade has been the observation of episodic tremor and slip (ETS) and nonvolcanic tremor (NVT) as a subset of the phenomenon (Peng and Gomberg, 2010; Vidale and Houston, 2012). Sensitivity of an NVT occurrence to very small, dynamic, low‐frequency stress perturbations in the Earth’s crust has been documented. For example, Rubinstein et al. (2007, 2008) reported pulsations of the envelope of the high‐frequency (generally above 1 Hz) tremors with much longer periods of Earth tides and surface waves from large earthquakes. The phenomenon has been...
