The Kenai Peninsula Borough is participating in tsunami preparedness week. On Wednesday at 9:45 a.m., a tsunami warning communications test will occur statewide.
The communications test will involve The National Oceanic and Atmospheric Administration (NOAA) Weather Radio All Hazards, the emergency alert system and other state and local communication links.
Radio listeners will hear an alert tone followed by an audio message describing the test, similar to the routine monthly tests of the emergency alert system.
Residents in some borough communities will hear sirens.
"Sirens are going to sound, and there will be a warning that goes out, but it is only a test," said Eric Morhmann, KPB Office of Emergency Management director.
It is important to note that some television systems are programmed to scroll a standard message based upon the emergency code received. In some cases, the message may not contain the word TEST, according to the NOAA. An audio message will say that it is a test, but if the volume is turned down or otherwise unheard, viewers may not realize the warning is a test.
Tsunami Preparedness Week, March 25-31, coincides with the anniversary of the Good Friday Earthquake -- a devastating 9.2 magnitude quake that triggered deadly tsunamis in Alaska on Friday, March 27, 1964.
