Low-Frequency Quakes Have Modest Effect on Slow Earthquake Cycle
Slow slip phenomena on subdaily scales, captured by seismic and GNSS data, show that low-frequency earthquakes are incidental to larger magnitude slow earthquakes, in which aseismic slip dominates.

Talc May Make Mexico’s Subduction Zone More Slippery
Production of the weak, water-bearing mineral at the interface between the Cocos and North American Plates could contribute to the occurrence of poorly understood episodic tremor and slow slip.

Are Low-Frequency Earthquakes Just Slow Slip?
Tests of seismic attenuation show fluid saturation and high pressure near a seismic source reduce high-frequency content, challenging the idea of slow slip as the cause of low-frequency earthquakes.
