At 10:15 a.m. Thursday, participants across the state will "drop, cover and hold on," the recommended action to take during an earthquake.
More than 5 million people participated in last year's Southern California ShakeOut drill, and 6.4 million have signed up so far for Thursday's statewide event.
The drill is sponsored by the California Earthquake Authority. Participants are encouraged to prepare for an earthquake, both physically and financially, ahead of the drill.
In San Francisco, the California Seismic Safety Commission will host a discussion at 9:30 a.m. Thursday. After the drill, the group will have an open meeting at 11 a.m. The event will be at the Hotel Whitcomb, 1231 Market St., San Francisco.
In San Jose, the Tech Center Museum will have events all week leading up to Thursday's drill. The museum is located at 201 S. Market St., San Jose.
