Magnitude 4.0 earthquake shakes southeast Missouri, says U.S. Geological Survey

WILLIAMSVILLE, Mo. (AP) — A minor earthquake shook residents of southeastern Missouri, according to the U.S. Geological Survey.

The survey said a 4.0 magnitude earthquake was recorded around 9 p.m. Wednesday in Wayne County, with the epicenter near Williamsville.

The Missouri Department of Public Safety said in a statement online that no injuries were immediately reported, but that some people reported pictures falling off walls.

The department said people as far away as St. Louis, Springfield and Memphis, Tennessee, reported feeling the quake.

The last "big" one on that fault was in 1968.

I was kid living in Southern Illinois and in the basement of big church when it hit. It was freaky and no one knew what it was since we never experienced any earthquake before.

All of a sudden, the water started rippling, and I hadn't moved! Freaky is right!

We were forty miles east of Knasas City.

I also lived in Southern Illinois (Herrin), and was at the First Baptist Church when it hit. I was only 7 at the time and really shook up.

"The 1811–1812 New Madrid earthquakes (/ˈmædrɪd/) were a series of intense intraplate earthquakes beginning with an initial earthquake of moment magnitude 7.2–8.2 on December 16, 1811, followed by a moment magnitude 7.4 aftershock on the same day. Two additional earthquakes of similar magnitude followed in January and February 1812. They remain the most powerful earthquakes to hit the contiguous United States east of the Rocky Mountains in recorded history."

Structures in that area are not earthquake resistant like in other earthquake prone areas.
