CRESCENT Topical Workshop
Fluids in Cascadia
April 23-25, 2025, University of Oregon Portland Campus, Portland, OR
Workshop Goals
Fluids in Cascadia Topical Workshop
Fluids are ubiquitous in subduction zones and play a fundamental role in modulating many observed processes along the megathrust and other related faults, including slip behaviors and deformation mode. This cross-disciplinary workshop brings together geophysicists, geologists, geochemists, and modelers to discuss the role of fluids in Cascadia.
Workshop topics include fluid sources (hydration of the oceanic slab, thermal and petrologic constraints on dehydration reactions, dewatering of sediments); fluid pathways, fluxes, and transport properties; pore pressure and fault strength; and fault slip/deformation behavior along the megathrust from the deformation front, through the seismogenic zone, and into the regions of slow slip and tremor and creep.
