Yes...Its called the Mid-Continent rift zone (I think)....It is an aborted rift zone that is still somewhat active (see the New Madrid Earthquake).

Fault Lines In Iowa

I don't know the precise location, but the Iowa Department of Natural Resources has an excellent web site. There appears to be only one fault line and only 4 earthquakes in Iowa's history.

Iowa boundaries correspond to the New Madrid Fault. The thing is the name is not precise, since it isn't tied into the continental plate as it should...
It is more like a regions where the Earth's crust throws its energy tension, by means of lava or .. you guess.. an earthquake .
Yopu have not seen this fenomena in the last generations, but do not forgett that on the 1800s the Mississippi River went crazy up to Minnesota in one hell of an earthquake, one of the worst in US history!

There's probably lots of little ones...but check out the lack of earthquake threat there...
