MR008:
Evolving Fault Zone Properties: From Co-Seismic Weakening and Damage Through Post-Seismic Fracture Healing





Session ID#: 22657

Session Description:
Understanding changes in fault-zone properties throughout the seismic cycle, over shorter characteristic times and at the appropriate length scales, are necessary to characterize earthquake occurrence and co-seismic effects.  Inter-seismic periods allow for kinetically sluggish processes to occur that might also have important feedbacks on co-seismic slip behavior.  We welcome contributions that explore processes and phenomena that alter the mechanical, chemical and/or hydrologic properties of seismic and aseismic faults.  Interesting studies may originate from rock-deformation experiments, geologic and seismological observations, and numerical modeling.
