...The Great Washington ShakeOut and Tsunami Siren Test -
Thursday October 17...

On Thursday, October 17th, 2024, at 1017 AM PDT, the National
Weather Service Forecast Offices in Seattle, Portland, Spokane,
and Pendleton will participate in the Great Washington ShakeOut
Earthquake and tsunami drill with state and local emergency
management officials. This is part of a global earthquake
preparedness effort.

Millions of people worldwide will practice how to drop, cover,
and hold on at 1017 AM PDT on October 17th during the Great
ShakeOut. Washingtonians can join them by registering for the 2024
Great Washington ShakeOut. Participation is a great way for your
family or organization to be better prepared to survive and
recover quickly from big earthquakes and their impacts. Over one
million people in Washington are expected to participate. Register
for free today at www.shakeout.org/washington

National Weather Service Offices across Washington will
disseminate a Required Monthly Test (RMT) message via the 21 NOAA
Weather Radio stations that serve the state to activate the
Emergency Alert System (EAS) and help kick off the Great ShakeOut
drill on October 17th at 1017 AM PDT. Broadcasters will carry the
EAS message on television and radio to help reach more of the
state`s residents, along with those who have NOAA all-hazard
weather radio receivers. This will not be a test of Wireless
Emergency Alerts (WEA) sent to cell phones. In coastal areas, the
Great ShakeOut earthquake and tsunami drill will also include a
test of the All Hazards Alert Broadcast tsunami sirens. The
purpose of the test is to get the public familiar with what the
sirens will sound like during a tsunami event. All of Washingtons
120+ tsunami sirens along the inner and outer coast will be
tested at 1017 AM using the real wailing sound of a tsunami
warning, not the Westminster Chimes that are typically used during
the monthly tests. Please dont call 911.

Preparedness experts encourage you to participate in the Great
ShakeOut. This is an audio recording you can use to make the
experience more realistic:
