All-Hazard Sirens (Tsunami)

PURPOSE - The Greater Ketchikan Area currently has two All-Hazard Warning Sirens sometimes incorrectly referred to as "Tsunami Sirens".  The primary function of these sirens is to warn the public regarding emergencies at the Carlana Lake Dam or Ketchikan Lake Dam and for Tsunami Warnings, but they can also be activated to notify the public regarding any type of natural or man-made disaster using the "Live PA" function.  The chart below contains additional detail on the various siren activation types.

TESTING - The sirens are tested on the 15th of each month at noon and consist of a series of  alarm tones and alternating voice announcements.

EVACUATING - If the sirens are activated and you here a "steady pulsed" tone or an "alternating hi-lo" tone you should immediately evacuate to higher ground.  If the siren is activated using the "live PA" function follow any directions provided.  In case of an earthquake that knocks you off your feet or lasts longer than 20 seconds DO NOT wait, evacuate to higher ground immediately!

The tsunami safety zone is anywhere more than 50' above seal level.  Tsunami evacuation route signs are posted along all evacuation routes and will direct you to designated tsunami shelters.  The Tsunami Evac Map can be used to help identify in advance the nearest evacuation route and tsunami shelter.
