There are hundreds of minor earthquakes each year in Missouri’s New Madrid Seismic Zone (NMSZ), but most of them are too small for people living in the area to feel. While several major earthquakes—magnitude 7.0 or greater—occurred between 1811-1812 in the NMSZ, none have happened since then, creating a knowledge gap in earthquake preparedness among people now residing in that area of Missouri, according to researchers at the University of Missouri.
