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 …

Trajectory models and reference frames for crustal motion geodesy

M Bevis, A Brown - Journal of Geodesy, 2014 - Springer
We sketch the evolution of station trajectory models used in crustal motion geodesy over the
last several decades, and describe some recent generalizations of these models that allow …

Ubiquitous weakening of faults due to thermal pressurization

RC Viesca, DI Garagash - Nature Geoscience, 2015 - nature.com
Laboratory simulations of earthquakes show that at high slip rates, faults can weaken
significantly, aiding rupture,,. Various mechanisms, such as thermal pressurization and flash …

Slow and fast ruptures on a laboratory fault controlled by loading characteristics

GC Mclaskey, F Yamashita - Journal of Geophysical Research …, 2017 - Wiley Online Library
Recent geodetic observations indicate that a single fault may slip slowly and silently or fast
and seismically in different circumstances. We report laboratory experiments that …
