As of today, over 41 million around the world are signed up to participate in the largest drills that require people to drop, cover and hold on.

The Great Shakeout is one of the biggest events of the year. "Each year it gets bigger - last year we had 72,000 participants and this year we have close to 70,000 and we're still increasing before tomorrow," said Jenna Gaminde, spokesperson for Guam Homeland Security/Office of Civil Defense. We're talking about the Great Guam Shakeout scheduled for Thursday, October 15."This is really southern California's initiative for the shakeout, and this is Guam's sixth year participating," she added.

On October 15 at 10:15am for one minute people around the globe participate in the Great Shakeout, an earthquake drill to prepare for the real thing. Gaminde said, "We're going to have staff staged in various areas so Harry S. Truman, Oceanview Middle School as well as the colleges and universities. GovGuam agencies have also registered as well."

Earthquakes can strike at anytime and anywhere, and we've all seen the destruction it can leave behind like in Chile last month, in Japan in 2011, and even here on Guam in 1993. "That was an 8.2, so we know that they're possible we know that they can happen here on the island. So it's very important to prepare for these, and so the best way to be prepared is to be informed," she added.

So when an earthquake strikes, you drop, cover and hold on!

It's as simple as that, and on Thursday at 10:15am that's what you'll be asked to do for one minute. And don't worry because Guam Homeland Security Office of Civil Defense will be making some noise to remind you by sounding off the island's fifteen all hazards alert warning system sirens. "Its going to be a very large event people island wide will be able hear these sirens and its really just our initiative to encourage in this drill during the length of the sirens."

If you haven't done so already, you can register online. Currently over 74,000 island residents plan to participate.

Oh, and when you do the drill, make sure post a video on social media using #shakeout. We just might use it on our newscast Thursday night.
