LOS ANGELES (CBS/AP) — Californians Thursday dove under desks and tables in an annual earthquake survival drill.

Nearly 10 million Californians took part in Thursday’s drill at 10:17 a.m.

Students at Rosement Avenue Elementary School were told by intercom to drop, cover and hold on before they were evacuated, KNX1070’s Jon Baird reports. Firefighters searched for “missing” students and helped those with pretend injuries while others took part in a simulated fire exercise.

“It’s estimated some 1,500 fires are going to break out in Los Angeles alone,” Todd Leitz of MySafeLA said.
