Mission Statement
The Cascadia Region Earthquake Science Center

In 2023, the National Science Foundation awarded $15 million dollars to establish the Cascadia Region Earthquake Science Center, CRESCENT. CRESCENT is the nation’s first subduction zone earthquake hazards center — a nexus for earthquake science and hazards research. CRESCENT has three overarching goals:
- To develop a better foundational understanding of Cascadia Subduction Zone earthquakes and their associated hazards and to transfer this knowledge to other subduction zones
- To promote diversity and to train the next-generation of geoscientists to address the challenges presented by our dynamic planet
- To provide a systematic approach to collaboration between researchers in academia and those in agencies that have mandates to produce hazard information that stakeholders, practitioners, and the public at large can trust and use
Please join us as we establish a new paradigm of collaborative Earth science research for societal good.

Major Activity
CRESCENT pillars

Three tenets comprise CRESCENTs core mission: advancing basic and applied science, geoscience education and training, and partnerships and applications of the science. First, the Cascadia Subduction Zone is a natural laboratory that is well positioned for significant scientific discoveries that will further understanding of subduction zone processes. Second, progress on the scientific challenges requires a concerted effort to prepare and diversify the next generation workforce. Finally, the goal of hazard research is to support the public good. Scientific discovery must be translated and delivered to communities and stakeholders in a meaningful and actionable way. The three committees below ensure progress on each of these fronts.
