MR41E:
Pore Fluids, Faulting, and (A)seismicity II


Session ID#: 7583

Session Description:
Recent studies highlight the important role pore fluids play in controlling fault slip and seismicity. Fluids are hypothesized to be first-order controls on: slow slip in subduction zones, dynamic weakening of mature plate boundary faults, and triggered seismicity associated with fluid injection. We invite contributions that investigate the mechanical and chemical effects of pore fluids on rock deformation and fault slip. Approaches that merge results of rock deformation experiments and field observations to understand geophysical observations, as well as those that use geophysical observations to infer mechanical processes, are particularly encouraged.
