(Los Angeles, CA) -- Millions of people around the world are gearing up for a major earthquake drill. More than 24-million people have signed up to duck under their desks, cover their heads and hold onto something sturdy. It's all part of a global effort to educate people on ways they can possibly survive a major earthquake. The Great ShakeOut was first held in California in 2008. This year, Japan, Canada, Italy and Guam plan to join in the drill. The Great ShakeOut begins at 10:17 this morning in each time zone.
