Thursday is the “Great American Shakeout,” an effort to raise awareness of being prepared for a major earthquake.  Hood River County Health Department director Ellen Larsen says at 10:15 a.m. Thursday, people are being asked to take part in an earthquake drill.  Rescue teams who have been dispatched to the scene of earthquakes continue to advocate use of “Drop, Cover, and Hold On.”  That means drop to the ground, take cover by getting under a sturdy desk or table, and hold on to it until the shaking stops.
