San Francisco Mayor Ed Lee, Fire Chief Joanne Hayes-White and Police Chief Greg Suhr took cover under a school desk in a third-grade classroom in the city's Bayview District Thursday morning as part of the Great California ShakeOut.
The ShakeOut -- the biggest earthquake drill in the nation, with more than 9.3 million registered to participate in California alone -- is meant to teach earthquake preparedness and safety.
Lee, Hayes-White and Suhr crouched under the desk in the front of a classroom at Dr. Charles R. Drew Elementary School during the 10:18 a.m. drill, showing their "drop, cover and hold on" skills.
At the start of the drill, a bell rang and a recorded voice said over a loudspeaker, "This is an earthquake."
The students remained calm under their desks, with one hand covering their necks and the other grabbing onto a desk leg. They then followed Lee, Hayes-White and Suhr to the schoolyard, where the entire student body met as part of the drill.
Once outside, Lee told students to convey the message of preparedness to their families, and to have an emergency kit ready at home.
"We want you all to be safe," Lee said. "We have to take care of things that might hurt us."
Before the drill, the city officials answered questions from curious third-graders, including one boy who veered off topic to ask the mayor's age.
Watchdogs are questioning an exclusive agreement between the City of Oakland and a non-profit group, tapped to lead a multi-million dollar project to redevelop the area around the Coliseum BART station.
