Session ID#: 24812
Session Description:
Subduction zones, one of Earth’s fundamental tectonic environments, play a key role in many Earth processes. Consequently, they require study by interdisciplinary methods. However, our understanding of subduction zones has been limited by a lack of offshore and amphibious data. At the Cascadia subduction zone, new data collected over the last several years have helped close this gap, elucidating a wide range of new insights, including the structure of the incoming lithosphere, the role of water and volatiles in the subducting plate, asthenospheric flow above and below the subducting lithosphere, the transition from locking to slipping behavior along the plate interface, and the nature of episodic tremor and slip. We invite contributions broadly related to Cascadia geoscience that focus on new results from seismology, magnetotellurics, geodesy, geodynamics, hazards, paleoseismology, geochemisty and petrology, with particular emphasis on insights gained from the contribution of offshore and amphibious data.
