A Holistic Perspective of Slow Slip in Subduction Zones: Integrating geophysical, geologic, experimental, and modeling insights.

This interdisciplinary workshop will bring together a wide range of scientific perspectives and expertise to understand the mechanisms and conditions of slow slip phenomena in subduction zones. Slow slip refers to shallow to deep aseismic transient slippage (slow slip events), which often is accompanied by tectonic tremor, low frequency earthquakes, and earthquake swarms.  The rock record also contains evidence of slow slip, and similar phenomena are observed in laboratory experiments, in natural analogs (e.g., landslides, glaciers), and computer models.

The output of physics-based ground motion simulations, earthquake relocations, and a number of other applications, depend heavily on the accuracy of seismic velocity models. In particular, if physics-based ground motion simulations are to be used towards seismic hazard assessment in the Cascadia Subduction Zone, they will require validation to assess their accuracy in predicting ground motion intensities.

This workshop will showcase existing efforts towards validation of the CRESCENT CVM, upcoming CVM updates, and host discussions of key needs and implications of validation work.
