Community Velocity Model Topical Workshop

May 13-14, 2024, 8:00 am – 12:00 pm PST – online

Meeting Goals

An online workshop to update the community on CRESCENT CVM goals and broaden the participation of/interaction with the Cascadia-focused research community. The workshop will include presentations and discussions on existing velocity models, velocity model creation workflows, model validation techniques, and uses of velocity models by various sub-disciplines and communities to further research agendas. We look to solicit feedback and create potential collaborations that can contribute to the success of the CRESCENT CVM by learning from prior experiences and better understanding community needs, uses, considerations, and potential pitfalls.

Meet The Team

CVM Leadership

The CRESCENT CVM team combines expertise in multiscale observational seismology imaging techniques (e.g., ambient noise, teleseismic, and local earthquake data, and onshore/offshore active-source data) with expertise in ground motion modeling and the typical applications and uses of a CVM. We will collaboratively produce a community model that is useful and applicable to a variety of subduction zone science applications including dynamic rupture modeling, structural and geologic interpretation, and ground motion modeling.
