Yes they do.
Yes, there are several fault lines in Michigan, but they are not very active compared to other regions in the United States. The most notable fault line in Michigan is the Lake Michigan Fault. It does not produce frequent or significant seismic activity.

equator

Yes, Meers fault. I am from Oklahoma and currently live in Norman, OK and we have had 65 "felt/registered" earthquakes in the past year; quite unusual. Normally, we have more earthquakes than any other region in the United States (including California) because we sit on top of one of the most active faults in the USA, but these earthquakes are extremely small and cannot be felt or heard. Recently though, the earthquakes have been registering about 3.0-5.0. We are doing studies on the causes right now and have not reached a conclusion on why these earthquakes have been occurring more frequently and stronger.
The Arkansas River (It also flows through Oklahoma).
Yes, both the eastern and western lines of longitude run through the Great Plains region. The westernmost line of longitude that runs through the Great Plains is around 100°W, and the easternmost line is around 95°W. The Great Plains region covers parts of several states, including Oklahoma, Kansas, Nebraska, South Dakota, and North Dakota.
