...The Great ShakeOut and Tsunami Warning Communications Test -
Thursday October 18...

On Thursday October 18, 2018 at 1018 AM PDT, the National Tsunami
Warning Center (NTWC) and the NWS Weather Forecast Offices in
Seattle and Portland, Oregon, will conduct a tsunami warning
communications test.  This test is in support of the Great
Washington ShakeOut statewide earthquake drill with state and local
emergency management officials, part of a global earthquake
preparedness effort.

Millions of people worldwide will practice how to drop, cover and
hold on at about 1018 AM PDT on October 18th during the Great
ShakeOut.  Washingtonians can join them by registering for the 2018
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.  Over one million people in Washington
are expected to participate.  Pre-register today at .

National Weather Service Offices across the state will disseminate a
Required Monthly Test (RMT) message via the 22 NOAA Weather Radio
stations that serve the state to activate the Emergency Alert System
(EAS) and help kickoff the Great ShakeOut drill. Broadcasters will
carry the EAS message to help reach more of the state`s citizens,
along with those who have all-hazard weather radio receivers.

In coastal areas, the Great ShakeOut earthquake drill will also
include the tsunami warning communications test.  The purpose of the
test is to evaluate communications for use in the dissemination of
tsunami warnings, watches and advisories.  For the first time, all
72 Washington tsunami alert sirens will be tested at 1018 AM using
the real sound of the siren, not the Westminster Chimes that
typically happen during the monthly tests.
