Millions of people throughout California have signed up to take part in a statewide earthquake disaster drill billed as the largest such exercise in U.S. history.
Many schools and businesses on Thursday will practice "drop, cover and hold on" - the minimum requirement for participation. Some hospitals and fire departments will stage more elaborate simulations complete with search-and-rescue missions and people posing as faux quake victims.
According to organizers, some 6.7 million people have pledged to take part.
