Megaquakes

I'm watching a show on the Science channel about the next great megaquake. They're talking about the Pacific Northwest here in America and it's kind of scary. I mean anyone growing up in America knows the Pacific coast is always at risk for a quake, but what they're talking about is horrific, real sink in the ocean and disappear, destroy the entire side of the continent type of damage. I don't know when it will happen, but after what happened in Haiti yesterday, it only brings the message of this program home.
