More than one million people in Washington are registered to participate in Thursday's Great Washington Shakeout earthquake drill including thousands in the Yakima Valley.  It's part of a worldwide campaign to practice "drop, cover and hold" at 10:18 a.m. Seismologist Bill Steele at the University of Washington says earthquakes do and will happen in the future and we all need to know how to survive.
Last year nearly 1 million people at schools, businesses and organizations were registered to take part in the event.  Washington is hit by hundreds of earthquakes every year. Most are too small to be felt. But, Steele says the "big one" could hit at any time with devastating injuries and damage.
