Dear Colleagues,



We would like to invite you to submit an abstract to our session on the
complexity in diffuse fault zones at the next AGU 2022 Fall meeting in
Chicago. The deadline for abstract submission is Wednesday, August 3rd.

Session description:

Multiple scales, multi-physics interactions and nonlinearities govern
earthquake source processes, rendering the understanding of how faults slip
a grand challenge of seismology. Earthquake fault zones are more complex,
both geometrically and rheologically than an idealized infinitely thin
plane embedded in linear elastic material. Complex volumetric failure may
lead to complexity in the nucleation process (e.g., instantaneous
vs.cascading ), rupture styles (e.g., pulses or cracks, sub-Rayleigh
vs.super-shear), slip distribution and energy balance. A realistic
understanding of co-seismic, post-seismic and interseismic slip across
diffuse fault zones should account for multi-physics coupling, nonlinear
visco-elasto-plastic rock rheologies, natural heterogeneities, etc.
Furthermore, diffuse fault zones evolve as potentially hierarchical fault
structures over space and time.

This session encourages contributions shedding light on, but not limited
to, volumetric faulting processes across different scales in both space and
time. We welcome interdisciplinary and focused contributions that explore
observations, laboratory experiments, numerical modeling and theoretical
studies.

Invited speakers for the session include:

Ahmed Elbanna (University of Illinois Urbana-Champaign)

Jessica Ann McBeck (University of Oslo)

We look forward to seeing you (either in person or virtually) in Chicago!

Cheers,

Duo Li, Munich University
