But New Madrid has experienced some big quakes in its history. Researchers have geologic evidence of several major earthquakes of around magnitude 7 and 8 striking the area over the past 4,500 years. More recently, the region experienced a series of strong quakes in 1811 and 1812. The first occurred in Arkansas on December 16, 1811, and scientistsâ best estimate for its strength is that it was a magnitude-7.7 earthquake.
