| SAFETY AT SEA?
: We recently received an
inquiry about protecting your boat from the impact of a tsunami by going
"to sea". According to the experts, you are relatively
safe only if you are in open waters of at least 200 fathoms (1,200
feet). Click
here to see more about tsunami safety for boaters. |

Tsunami
sirens are tested every other month on the first Monday of the month at
12:00 noon. Test tones are different than the actual "siren"
sound.
CLICK HERE to
hear what the test sounds like. The duration of the test tone
sequence is about 5 seconds.
CLICK HERE to hear the actual
emergency warning siren. The duration of the actual emergency
siren is 30 seconds. |

Point Hudson "All Hazards Alert Broadcast" (AHAB) unit, one of three AHAB
tsunami "sirens" in the Port Townsend area. The first
AHAB in Washington State was installed at the Port Townsend Marina in
2003. A unit similar to the Point Hudson siren is located on the
beach near the campground at Fort Worden. AHABs can be activated
by satellite from the State Emergency Operations Center or by radio from
the Jefferson County EOC. There are currently 45 AHAB
installations in Washington State. |
