Washington's Great ShakeOut is scheduled to take place at 10:18 a.m. Thursday morning.
More than 713,000 people are signed up to drop, cover, and hold on.
The main goal of the Washington ShakeOut is to teach residents how to prepare for major earthquakes.
Most of Washington is prone to earthquakes and you could be anywhere when one strikes: at home, work, school, or the store.
In 2001, the Nisqually Earthquake that hit Western Washington was one of the worst quakes in recent history.
Washington joins a number of other states and countries for the first time in participating in the Great ShakeOut. Also taking part October 18 are Calif., Nevada, Oregon and Southern Italy.
Anyone can participate in the Great ShakeOut by signing up at the website.
