Tillamook County Tsunami Siren Activation Procedures Tsunami following an earthquake with local ground shaking. Distant Tsunami
Earthquake WITH ground shaking Likely we will have damage to local infrastructure including power, telephone and roads Earthquake is your warning May or may not be associated with Cascadia Subduction Zone Quake
Earthquake WITH ground shaking We recommend people do not wait for official notification if they live in/near low-lying coastal communities (inundation zone) before moving inland. Cascadia event gives you approx. 20 minutes to get out of tsunami zone! If earthquake felt, residents should tune into local radio stations and monitor NOAA All- Hazard Radios, and internet if available.
