In the early hours of December 16, 1811, the residents of New Madrid, a Mississippi River town once part of the Louisiana Territory, rushed from their homes as the ground rolled beneath their feet. Trees were uprooted and thrown to the ground. Huge chasms opened in the earth, swallowing whatever had been perched above. The powerful river ran backward.
“The screams of the affrighted inhabitants running to and fro, not knowing where to go, or what to do; the cries of the fowls and beasts of every species; the cracking of trees falling … formed a scene truly horrible,” eyewitness Eliza Bryan wrote in a letter later published in the book History of a Cosmopolite.
The earth had slipped somewhere deep beneath New Madrid, resulting in powerful earthquakes that killed many dozens of people, destroyed thousands of acres of virgin forest, and was felt across one million square miles. At the White House, nearly 900 miles away, President James Madison claimed he felt the earth quiver several times during the winter of 1811-1812. Alarmed, on February 7, 1812, he wrote to his political ally and lifelong friend, Thomas Jefferson: “The re-iteration of earthquakes continues … There was one here this morning at 5 or 6 minutes after 4 o’clock. It was rather stronger than any preceding one, and lasted several minutes …”
Madison had a reason to be concerned. From December 16, 1811 through March of 1812, thousands of earthquakes and aftershocks hit America’s Midwest and the Missouri Bootheel. Three are among the largest tremors ever recorded in the United States. While contemporary estimates place these quakes around 7 on the Richter scale, the U.S. Geological Survey (USGS) has their magnitudes recorded slightly higher: December 16, 1811, 7.5; January 23, 1812, 7.3; and February 7, 1812, 7.5. Each of the three largest quakes lasted between one and three minutes, and the tremors continued for decades.
