The seismograph was not invented until the later part of the nineteenth century. So the magnitude and exact locations of the earthquake(s) that occurred on the New Madrid Fault (or Reelfoot Rift ) in 1811 and 1812 are not known. Evidence from "sand blows" indicate the epicenter of one of the larger ones that occurred on February 7 of 1812, was near the town of New Madrid, Mo.
