'San Andreas' star Dwayne Johnson says in a real quake, 'drop, cover and hold on'

What do you do when an earthquake hits?

Whatever the Rock tells you to do.

In the new disaster flick "San Andreas," Dwayne Johnson fights his way through a destructive quake and its aftermath in order to rescue his daughter (Alexandra Daddario).

While the film strays from scientific research in the name of Earth-shaking excitement -- CG-rendered buildings topple spectacularly, tsunamis speed toward the Golden Gate Bridge and giant chasms open up beneath our hero's feet -- Johnson wants viewers to know what to do when an earthquake hits and he's not there to save you.

Working with the Federal Emergency Management Agency (FEMA) and the Ad Council, Johnson appears in a pair of PSAs preparing viewers for seismic disasters.

As Johnson states, "Movies are one thing," but in reality the best thing to do is to "drop, cover and hold on."

"As a father, safety is always a top of mind issue for me," Johnson explained in a press release. "That’s why I am proud to be partnering with FEMA and the Ad Council, to make sure as many people as possible know what to do in the event of an earthquake. They can happen anywhere in the U.S. without warning, so if you ever find yourself in the middle of one, remember – drop, cover and hold on."

Hero Complex readers get a first look at the new PSAs. Watch the brief clip at the top of the post, and here's a longer version if you're still unclear about how to prepare.

"San Andreas" is now in theaters.
