(AP) - California is bracing for its annual fake earthquake.
Millions across the state are expected to simultaneous take cover Thursday morning in the yearly drill known as the Great Shakeout that began in 2008.
Schools and universities account for most of the participants in the simultaneous disaster drill that has also begun to spread beyond the state.
Organizers say more than 10 million Californians are slated to take part in the drill at 10:15 a.m.
For many the exercise just consists of dropping and covering under desks as generations of California schoolchildren have done. But the Great Shakeout is designed to simulate more coordinated and widespread action.
On some school campuses, student act out roles as earthquake victims, as health care professionals assess and treat them.
