Septem ber 1, 2018 Dear Emergency Management Partner, Preparing for a Cascadia Subduction Zone earthquake and ensuing tsunami may seem like a daunting task, but each step we take to prepare helps make Oregon more resilient. The Cascadia Playbook is the blueprint for preparing for a large scale catastrophic event, bu t it also guides respon ses to other emergencies and incidents. It has been over three years since the Oregon Office of Emergency Management first published the Cascadia Playbook. Since then, the Playbook has improved the resilience of state agencies and serves as a national model for preparedness and readiness. We have also learned quite a bit since the first edition of the Cascadia Playbook was released, and have gained important new insights from navigating both real- world events and training exercises. The protocols included in the Cascadia Playbook helped emergency management partners work efficiently and collaboratively in response to the Mosier train derailment in 2016. The Playbook was also instructive during the massive and successful planning effort for the historic 2017 solar eclipse that attracted an estimated one million viewers from around the world. Even our multi-agency response to Oregon wildfires has been improved in thanks to the Playbook. As Governor, keeping Oregonians safe and healthy is my top priority. Providing the structure for how response partners come together to address Oregonians’ most urgent needs is the first step to keeping us all safe and informed in a catastrophic incident. The ongoing refinement of the Cascadia Playbook ensures coordinated efforts of local, tribal, state, and federal agencies with non-profit and private sector partners across Oregon and th e country long into t he future. The Playbook accomplishes three essential functions:



Prescribes the mission assignments to organize the efforts of the many partners within emergency response and recovery.



Provides a checklist of time-based actions to be accomplished by teams of subject matter experts working collaboratively as Emergency Support Functions.
