The Great Lakes is a very safe area to live in, virtually immune to all natural disasters. Tornadoes are a rare occurence in this are usually only having one or two in a given 50 mile area every year or so. The threat of a super volcano doesn't stretch far enough to effect the great lakes nor does a massive earth quake.
The only threat is flooding which is usually weak and only comes every 10 years or so.
And we're currently in year 4 of a drought!
