The C3S working group is organizing a community exercise to evaluate and compare approaches for detecting slow slip events along the Cascadia Subduction Zone from continuous GNSS observations. All participants work with a common 2010–2025 dataset and submit candidate events in a standardized format, providing a basis for comparing different detection approaches.

The exercise is intended to encourage collaboration, reproducibility, and the development of new approaches, with code and results remaining available for ongoing community use. Exercise documentation and submission links are provided below.

Using the Cascadia CoPes Hub Sources for Tsunami Modeling – A set of Virtual Sessions being organized by the CRESCENT Special Interest Group on Tsunami Sources for Hazard Assessment.

This interdisciplinary workshop aims to integrate experimental, imaging, and modeling studies on shallow faulting and deformation and tsunamigenesis for the Cascadia Subduction Zone.  We welcome participants interested in frictional fault properties, aseismic slip, fluid pressure, splay faulting, off-fault deformation, acoustic laboratory studies, seafloor geodesy and remote sensing, and offshore DAS.  The workshop will generate a community white paper focusing on how to better account for the complexity of shallow deformation to assess tsunami hazard for Cascadia.
