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.
A big earthquake in 1812
This is actually a two part answer:1. The largest earthquake in continental US history. A: March 27 1964, Prince William Sound Alaska. 9.22. The largest earthquake in the Contiguous US history.A: New Madrid. 1811 - 1812, 7.9Facts: A series of earthquakes hit the New Madrid seismic zone of southeastern Missouri, northeastern Arkansas, and adjacent parts of Tennessee and Kentucky, in December 1811 to February 1812. Three earthquakes had a magnitude of 7.0 or greater. The first earthquake 7.7 occurred December 16, 1811, at 2:15 a.m.; the second 7.7 at 9 a.m. on January 23, 1812; and the third 7.9 -8.0 on February 7, 1812, at 3:45 a.m. These three earthquakes were among the largest to strike North America since European settlement.The main shocks were followed by many hundreds of aftershocks that lasted for decades. Many of the aftershocks were major earthquakes themselves. The area that was strongly shaken by the three main shocks was 2--3 times as large as the strongly shaken area of the 1964 M9.2 Alaskan earthquake, and 10 times as large as that of the 1906 M7.8 San Francisco earthquake.
Indiana and a number of neighboring states experience earthquakes, which in modern times have been small and nondestructive. It is unusual to have a major fault in the middle of a continent, but that does exist in this region.Southern Indiana is close to the New Madrid fault. New Madrid, now in Missouri, was the location of the New Madrid earthquakes, 1811-1812, which historical accounts suggest were the largest ever recorded in the eastern US and possibly the largest in North America. The fault is now well mapped and the active area includes several neighboring states and much of Indiana.

Charles Cameron - architect - died in 1812.
The New Madrid Earthquake on February 7, 1812 is estimated to have measured 8.0 magnitude.
The 1812 New Madrid earthquake caused serious land deformations and the river flowed backwards for 10-24 hours and created Reelfoot lake
The 1812 earthquake, known as the New Madrid earthquake, occurred in the central United States near the town of New Madrid, Missouri. It is considered one of the largest earthquakes to ever hit North America.
In 1811-1812 the New Madrid earthquakes took place. I'm not sure if this is the one you mean, but I hope so. The 1812 Febuary earthquake had a magnitude of 7.7 on the Richter scale.
1811/1812 earthquake along New Madrid fault line. Mississippi river ran backwards three days and made lake
The 1811-1812 New Madrid earthquakes are a rare example of large earthquakes occurring in the middle of a plate, there was no plate boundary involved.
The mission suffered from a devastating earthquake in 1812.

An earthquake in Venezuela in 1812 distroyed a city.
Im trying to figure that out to for my science project go to www.earthquake.usgs.gov/regional/states/events/1811_overview.php and it will help you out! :)
