More than 20 million people around the world on Thursday are expected to take part in the Great ShakeOut Earthquake Drills, an annual event that promotes earthquake readiness.

At 10:16 a.m. on Oct. 16, participants will practice the government-recommended “drop, cover and hold on” protocol, which involves getting on the ground, taking cover under a table or desk and holding on until the earthquake is over.

With 10.32 million people registered, California has the highest participation of any U.S. state or nation taking part. ShakeOut events are also happening inNew Zealand, Japan, Southern Italy and parts of Canada as well. More than 25 million people in total are participating in a ShakeOut event of some kind during 2014, according to the Great ShakeOut organization.

ShakeOuts started in California, where earthquakes are common, but soon spread to other states, and the drills are usually coordinated with local emergency services.
