"SIKESTON — The U.S. Geological Survey said a small earthquake shook southeast Missouri along the New Madrid fault.The agency says the magnitude-3.7 earthquake was detected at 1:37 p.m. Tuesday about 15 miles south-southeast of Sikeston. No damage was reported.
The temblor was felt as far away as Alton, Ill., and St. Peters, both about 150 miles north of the epicenter.
The earthquake occurred within the New Madrid seismic zone, which includes southeastern Missouri, northeastern Arkansas, southern Illinois and western Kentucky and Tennessee.
More than 200 small earthquakes occur within the seismic zone each year.
The New Madrid fault is infamous for a series of big quakes, estimated between 7.2 - 8.1, during the years 1811 & 1812.
"The area of strong shaking associated with these shocks is two to three times larger than that of the 1964 Alaska earthquake and 10 times larger than that of the 1906 San Francisco earthquake."
Eye witnesses reported the Earth 'heaving', the Mississippi river running backwards, and church bells rung in Cincinnati, Ohio.
