Biggest Missouri Earthquake that Wasn’t New Madrid Hit KC in 2011

I lived in Missouri in 2011 and I am an earthquake nerd, yet I don't remember what was the largest quake to hit the state that didn't originate from the New Madrid Fault Zone that hit that year.

This question came up when I saw a brand new article from 24/7 Wall St about the biggest earthquakes to hit the most surprising places in America. Of course the historic 1811/1812 New Madrid quakes made their list, but it was another one that struck Missouri that I had never heard of.

What is Missouri's largest non-New Madrid Fault Zone quake?

According to City Data, not only did this earthquake happen in a strange part of Missouri, but also an unusual time of year. It was a magnitude 5.7 earthquake that happened in the early morning hours of November 6, 2011 in Platte County, Missouri in the Kansas City area.

For the record, a 5.7 magnitude quake is capable of doing significant damage, but there were fortunately no serious injuries or fatalities that happened during that Platte County, Missouri quake.

Platte County, Missouri had a very recent 3.5 earthquake a few weeks ago that is now believed to have been caused by a mine collapse.

We know that Missouri is a very seismically-active state because of the New Madrid Fault Zone. We're just not accustomed to large quakes happening in other parts of the state, but the 5.7 in 2011 is proof they can and do occur.
