Millions of people will "drop, cover and hold on" during a statewide earthquake simulation Thursday.
The Great California ShakeOut is an annual event that aims to raise awareness about how to prepare for a major quake.
The ShakeOut will begin at 10:18 a.m., when participants across the state will practice what to do when an earthquake hits. More than 9 million people have registered to join the exercise so far, including 96, 530 in San Mateo County.
In Millbrae, Taylor Middle School and Mills High School have registered to participate.
Here are other ways to participate in the Great Shake Out, as posted on shakeout.org.
Coming just a day after the anniversary of the Loma Prieta Earthquake, the preparedness drill carries special significance.
The ShakeOut is intended to simulate the impact of a magnitude-7.8 earthquake originating from the southernmost area of the San Andreas Fault. Under this scenario, a tectonic shift would produce waves of movement for hundreds of miles over four minutes.
