Tsunami Evac sign


A LOCAL TSUNAMI could come onshore within 15 to 20 minutes after the earthquake  - before there is time for the official warning from a national warning system. 

Ground-shaking from the earthquake may
be the only warning you have. Evacuate quickly!



A DISTANT TSUNAMI may take hours to come ashore and the tsunami will generally be smaller than that from a local earthquake. 

There will typically be time for an official warning and evacuation to safety

In Event of an Earthquake Protect yourself - 


until the earthquake is over then move quickly inland to High Ground and away from low-lying coastal areas Go on foot if possible Do not wait for an official evacuation warning Do not pack or delay in evacuating Do not return to shore Wait for an “all clear” from local officials before returning to low lying areas Listen to local radio for updates 


In Event of a Tsunami Warning
Do not hesitate to evacuate. Follow Tsunami Evacuation Route signs to safe zones (High Ground) Police Officers and Firefighters will be at main intersections to assist the public and to control traffic. 
Only call 9-1-1 in case of a true emergency
Our volunteers and City Staff will be busy handling evacuation procedures.


Siren Warnings -

The sirens work in conjunction with a reverse 9-1-1 system, alerting residents in low-lying areas that they need to head for higher ground. The sirens will go off every hour ( with Instructions in English and Spanish) until the final hour; at that point, they will go off approx: every 15 minutes. With a final high-low (an ambulance siren-like tone)

as (heard in the video above)
