From geodetic imaging of seismic and aseismic fault slip to dynamic modeling of the seismic cycle

JP Avouac - Annual Review of Earth and Planetary Sciences, 2015 - annualreviews.org
Understanding the partitioning of seismic and aseismic fault slip is central to seismotectonics
as it ultimately determines the seismic potential of faults. Thanks to advances in tectonic …

Stress triggering in thrust and subduction earthquakes and stress interaction between the southern San Andreas and nearby thrust and strike‐slip faults

J Lin, RS Stein - Journal of Geophysical Research: Solid Earth, 2004 - Wiley Online Library
We argue that key features of thrust earthquake triggering, inhibition, and clustering can be
explained by Coulomb stress changes, which we illustrate by a suite of representative …
