  1. Tillamook County Gordon McCraw Director Emergency Management

  2. Tillamook County Tsunami Siren Activation Procedures • Tsunami following an earthquake with local ground shaking. • Distant Tsunami

  3. 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

  4. 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.

  5. Distant Earthquake Tsunami Recent events gave valuable lessons

  6. Recent Distant Tsunami Lessons Learned • Tsunami Warning Center’s times and locations very accurate, size weak. • Extremely distant, non-perpendicular events appear to be minor events on other side of ocean. • Advisories mainly cautioning that beach goers and harbors could be effected

  7. Tsunami WarningsNo or little Ground Shaking • Likely a large quake in Alaska. • Partial Subduction Zone quake • Maybe large quake in Japan

  8. Distant Tsunami Notification Procedures • 911 activates Pager Tones for all Fire, EMS, and Incident Command Team personnel • Broadcast information on above pagers and Fire/Police Radio channels. • Sirens Activated according to the following schedule.

  9. Siren Activation Schedule • 3 hrs prior • 2 hrs prior • 1 hr prior • 30 min. prior • 15 min. prior • 3 minutes in duration each time

  10. Other Notification Methods • Police and Fire Units • Radio (Coast105, KTIL) and other radio and TV stations. • Gordon’s Email distribution list. • Twitter (www.twitter.com/TillamookCoEM) • Facebook (through Coast105 and KTIL) • Phone notification lists

  11. Deactivation • Same Pager Tones used during Activation • Radio, TV, NOAA Radio • Scanner, Ham radio • City, County, Forest and State Patrol Units

  12. Subduction Zone Major Quake • Likely NO Sirens • Severe ground shaking is your warning • All infrastructure will be effected for weeks/months • Many structurally damaged homes, slides, deaths and injuries BEFORE the tsunami even hits.
