I think this is the most precise prediction I’ve heard about the New Madrid fault. I’d be curious as to what they base it on.

It's based on the desire to create hysteria. Some scientists think New Madrid is finished. The latest studies indicate that there is zero fault movement.

The one to worry about may be the Wabash fault.

I personally doubt this one is a dead fault but it does happen. Michigan's upper Penninsula has some old fault lines that have never produced a quake that we're aware of. The lake superior basin is formed in an ancient rift vally which means it was once very geologically active. I believe lake Ontario is also in an ancient rift vally. They're both billions of years old, have filled with sediment and been recarved out by glaciers. As I understand it, this is why both are so much deeper than the rest of the lakes.
