I’ve heard that maybe the Plum River Fault Line does, but I can’t find anything to back that up. If you could site your source(s) that would be great! Thanks!

The Plum River Fault Zone is a 112 mile (180 km) long, east-west trending zone of high-angle faulting in east-central Iowa and northwest Illinois.

Here is a usgs map. Just click on your state.
1st answer covered Plum River very well.
If you are looking for possible problem areas the New Madrid area is close enough to cause trouble for Iowa and has in the past.

The fault line in Eastern Iowa is called the Plum River Fault line named after the Plum River By Savanna IL. The line runs from South of Cedar Rapids to Rockford IL.
