As a resident of Columbus, I agree. The New Madrid fault is the one that scares me.
None of these cities in the zone has not bothered to lift a finger to upgrade their buildings and espcially bridges over the Mississippi River.
Madrid faultline would affect me. After learning about the Haiti earthquake, my first thoughts turned to where I live (Atlanta) and remembering one of the worst earthquakes in the early 1800’s. It was worse than the SF earthquake of 1906.
