At 11 o’clock Friday morning, Florence residents on the Oregon coast will hear sirens. The drill will test the state’s new Tsunami Blue Line Project on the 5th anniversary of the Tsunami and Earthquake that hit Japan.

Tsunami warning sirens wailed up and down the Washington coast Thursday. Students, businesses and medical workers drilled for an earthquake and tsunami as part of an annual event called "The Great Shakeout."

More than 1.5 million Northwesterners signed up to take part in this year's "Great ShakeOut" on Thursday morning. While "drop, cover and hold" is part of the annual earthquake safety drill everywhere, some coastal schools and offices followed up with tsunami evacuation practice.

The state of Oregon has updated its master plan for what to do in case of a major earthquake and tsunami.
