Geoscience research is at the forefront of characterizing the earthquake risks associated with the Cascadia subduction zone in the Pacific Northwest. This webinar informs listeners of the science and its implications for policy decisions and resiliency efforts. During the webinar, the three presenters will provide an overview of what we know about the Cascadia subduction zone and the associated earthquake risk, how this information is used to guide policy decisions, how the science should be communicated, what state and local governments are doing to address the risks, and what more could be done to better protect the Pacific Northwest.
Overarching questions addressed in this webinar include:
- What does geoscience tell us about the risk posed by the Cascadia subduction zone?
- How is earthquake science used in the decision-making process?
- What challenges do state and local decision makers face responding to the threat of large-scale earthquakes in their area?
- How can information about earthquake risk be communicated effectively to decision makers and the public?
- What actions are state and local decision makers taking to prepare for the risks posed by Cascadia and other similar faults? What other actions could be taken?
