Over a dozen new AHAB sirens added locally
16 new tsunami alert sirens have been added within our area, including 12 in Grays Harbor and 4 in Pacific County, to alert the public of an emergency situation, and all will be included in upcoming tests.
According to the Washington Military Department, the local additions were among 50 new All-Hazard Alert Broadcast (AHAB) sirens added throughout the state.
Officials state that the new installations fill gaps within the tsunami warning infrastructure, completing the statewide tsunami siren network.
“Without the funding from the Washington state Legislature and the hard work and dedication of partners across Western Washington, completing the siren network could have taken another 20 years.”
With these new units, there are now 122 sirens on the Washington coast, which are run and maintained by the state.
The state installed the first siren in 2005, and over the next 15 years, brought that number to 72. The last 50 sirens took about two years to install, which the state department calls “an unprecedented achievement”.
AHAB tsunami sirens are intended to act as an outdoor tsunami alerting method for people and communities on or near the coast who may not otherwise have access to other official alerting methods via radio, TV or their smartphones.
“This is especially helpful for “distant” tsunami events from places like Alaska, Japan or Southeast Asia. The tsunami sirens are NOT meant to be heard inside. Residents should invest in NOAA Weather Radios to hear tsunami alerts while inside their homes.”
The Washington Emergency Management Division coordinated with state, tribal and local partners to identify and fill the tsunami siren gaps for high risk communities.
Local partners may decide on their own to add more sirens as the years progress.
“This life-saving project brought together state agencies, tribal, county and city emergency management as well as other important stakeholders to ensure Washington’s coastal communities can be alerted in the event of a tsunami warning,” said Maximilian Dixon, the geologic hazards supervisor for the state Emergency Management Division.
Dixon says the state’s attention now will be to improve tsunami evacuation route signage, as well as working with local officials on vertical tsunami evacuation structures.
During a routine test of the tsunami siren system, which is conducted on the first Monday of every month at noon, all AHAB sirens are scheduled to play the Westminster Chimes (click here to listen to what it sounds like). The sirens are also tested once a year with the actual wail sound on the third Thursday in October on #ShakeOut Day (click here to listen to what it sounds like).

FAQ from Washington Military Department
All 3,000 miles of Washington’s coastline are at risk of tsunamis. For local tsunamis, those caused by nearby earthquakes, the groundshaking is your warning that a tsunami could be on the way. However, for distant tsunamis, those caused by earthquakes in other parts of the world, there is no groundshaking to warn you about the approaching danger. Tsunami sirens therefore play an integral role in ensuring Washington’s public receives ample warning for distant events. The sirens have an audible range of approximately 1 mile, though this varies depending on environmental factors like topography, wind direction and physical barriers. The pole-mounted voice/tone sirens are also topped with a blue light for the hard of hearing. The sirens are not intended to be heard indoors.
The siren system is tested on the first Monday of every month at noon. The sirens play the Westminster Chimes followed by an audio message in English and Spanish. The sirens are also tested once a year with the actual tsunami warning wail sound on the third Thursday in October in conjunction with the Great Washington ShakeOut earthquake and tsunami drill.
Know Your Tsunami Warning Signs
If you hear the siren wailing sound, or you receive a tsunami warning through your smartphone, TV, radio, or other alerting method, immediately follow the closest tsunami evacuation route inland or to high ground. This is your warning that a tsunami is approaching and you need to evacuate the inundation zone as soon as possible.
If you are on the coast and you feel ground shaking, drop, cover and hold on to protect yourself. When the shaking stops, immediately follow the closest tsunami evacuation route inland or to high ground. Do not wait to hear a tsunami siren or to receive an official tsunami alert – the shaking is your warning that a tsunami may be on its way.
