It's no comparison by size here, but the New Madrid fault shifted on us too. Caused a 3.7 quake. If you guys don't know where this one is at, it's in the boot heel of Missouri. If it goes off, the entire US is gonna feel it. It's a doozy.
Seriously though, the one in Chile was devastating, it shortened our days by 1.26 milliseconds. That takes some power.
