On average, Oregon receives about one distant tsunami warning, advisory, or watch per year. This Guidance Document, from the Oregon Distant Tsunami Working Group, is intended to ensure that there is a standardized response in order to protect life and property. Response to a distant tsunami is significantly different than that of response to a local tsunami. Because tsunami are not very common, response personnel may not have experience in dealing with them. Public confidence in emergency management and first responders can be eroded by a conflicting and confused response. This can cause inappropriate actions by an under-informed population. In this document, local emergency management personnel and first responders will find a road map that can be adopted into current response structures. It was developed through the collaboration of many local, county, and state agencies.
