AGU Session “Knowns and Unknowns of the Cascadia Subduction Zone”

Wednesday, June 27, 2018

Please consider submitting an abstract to the AGU session T044 "Synthesis: Knowns and Unknowns of the Cascadia Subduction Zone":

The Cascadia subduction zone is a global end-member warm-slab subduction zone and exhibits along-strike variations in subduction parameters (e.g., incoming plate age) and mechanical behavior (e.g., seismogenesis), serving as a unique natural laboratory to investigate a range of subduction zone processes, including tsunamigenic megathrust earthquakes, episodic tremor and slip, and arc volcanism. As these processes pose natural hazards, understanding their underlying causes is critical to natural hazard mitigation. The recent influx of offshore and onshore geophysical, geochemical, and geological data provides new opportunities to evaluate the entire Cascadia subduction zone in a coherent and consistent manner at various length and time scales. This session aims to synthesize recent findings and outstanding questions about this subduction system and the processes that occur within. We invite contributions from a wide range of disciplines, including (paleo)seismology, earthquake mechanics, geodesy, magnetotellurics, geochemistry, petrology, volcanology, structural geology, rock mechanics, and geodynamics.
