Where is the fault line in Minnesota?
I can't find any maps on this subject and I am just wandering where exactly they are. If you could give me a cite where I can look at a map I would greatly appreciate it. Also can you tell me how long the fault line has actually existed? Please no answers saying "millions" of years old.

Hi - I actually lived in Morris, MN in the early-mid 1990's when there was some earthquake in the area. I also studied Geology at that time at the Univ. of Minnesota in Morris.
There are actually several faults throughout Minnesota. Check out page 3 of this publication for a map: http://www.morris.umn.edu/earthquakes/glance.pdf
There's a larger version here: http://www.morris.umn.edu/earthquakes/epicenters2....
You can also see the faults on this map: http://www.morris.umn.edu/earthquakes/Images/bdrkm...
Both of these came from this site: http://www.morris.umn.edu/earthquakes/index.html
Dr. Peter Whelan has passed away, so you won't be able to contact him as the previous poster suggested.

Most of the Earthquakes in Minnesota occur along an area called the "Great Lakes Tectonic Zone". Here's a map of the zone: http://www.winona.edu/geology/MRW/mrwimages/GLTect...
This zone is the result of two different plates colliding about 2.6 billion years ago (early Pre-Cambrian). One plate was a land mass about 3.6 billion years old and the other was about 2.7 billion years ago. A good explanation is here:
If you need more info try googling "Great Lakes Tectonic Zone"

There are fault lines everywhere and cause no harm to anyone. The problem occurs where there is a fault line between techtonic plates eg around the Pacific and there is movement. Snow would have zero effect on any fault line so don't worry. just avid visiting California!

here are some places to start
I would contact the sources, any links....then you may get maps....I am having tough time locating maps of fault lines in Minnesota, too.....It is one of the quietest parts of the country for earthquakes.
