T044:
The interplay between fault properties, structure and (a)seismic slip processes





Session ID#: 23006

Session Description:
Hydro-mechanical properties of fault zones such as poro-elastic
coupling and frictional stability are intrinsically connected to
structural evolution (e.g. slip localization and changes in roughness)
and slip characteristics from episodic tremor and creep to slow-slip
and large earthquakes. While exhumed faults provide insight into
long-term deformation, much remains unknown about in-situ processes at
seismogenic depth. This disconnect may be bridged by laboratory
experiments and seismological analysis. We solicit experimental,
seismologic and geologic studies of fault structure, hydrology, and
slip localization. Topics of interest might include: fault roughness
evolution and mirror-like surfaces, observations and mechanics of slip localization and
delocalization, feedbacks between fault properties and rupture
dynamics, novel methods to observe strain localization in lab and
nature, coupling natural fault structures with seismicity distributions, effects of
environmental conditions (e.g. water content, temperature, confining
pressures) on earthquake nucleation and slip behavior, and slip
processes in near surface environments, such as under glaciers and
landslides.
