Most Southern California Mainshocks Follow Foreshocks

by G. P. Hayes 19 September 20196 October 2021

New research using a highly complete earthquake catalog shows that 72% of M4+ mainshocks are preceded by foreshocks, implying that foreshock activity is much more prevalent than previously thought.

Shallow Low Frequency Tremors in Japan Trench

by G. P. Hayes 14 June 20196 December 2021

A new seafloor seismic network detected low-frequency tremor on the subduction zone interface offshore northern Japan, indicating regions of slow slip in close proximity to shallow megathrust events.

A New Spin on Grain Segregation in Fault Zones

by G. P. Hayes 14 September 20186 October 2021

Fine-grained layers in sheared fault gouge may be formed by shear-driven size-segregation in granular materials, rather than by shear localization.
