New simulations show earthquakes can reverse direction within seconds on simple, uniform faults, suggesting back-propagating subevents are more common than previously thought.

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.

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.
