More than half a million Bay Area residents have signed up for a statewide earthquake drill in October to mark the 20th anniversary of the Loma Prieta earthquake, event organizers said Thursday.
The Great California ShakeOut is scheduled for 10:15 a.m. on Oct.15 and will give residents a chance to improve preparedness and practice protective actions, according to U.S. Geological Survey spokeswoman Susan Garcia.
The 6.9-magnitude Loma Prieta quake rumbled the Bay Area on Oct. 17, 1989, and the USGS says there is a 63 percent chance an earthquake with a magnitude of 6.7 or greater will occur before 2032.
Last year, 5.4 million people participated in the Great Southern California Shakeout, before the drill became statewide.
