Earthquakes of 1811 - 1812

Two Hundred years ago the earth rolled and swayed, causing great fear in western Kentucky and beyond.  A series of earthquakes centered on the New Madrid fault line  began in the early morning hours of the 16th of December 1811. The earth split open, sometimes swallowing animals, trees and even people.  The earthquakes  were felt as far away as Charleston, South Carolina and Quebec, Canada.

The following account was given in a letter to a gentleman in Lexington from a friend at New Madrid, reported in the  Kentucky Reporter and accessed on GenealogyBank.

 "About two o'clock this morning we were awakened by a most tremendous noise, while the house danced about, and seemed as if it would fall on our heads. I soon conjectured the cause of our trouble, and cried out it was an earthquake, and for the family to leave the house, which we found very difficult to do, owing to its rolling and jostling about. The shock was soon over and no injury was sustained except the loss of the chimney, and the exposure of my family to the cold of the night. At the time of this shock the heavens were very clear and serene, not a breath of air stirring, but in five minutes it became very dark, and a vapour which seemed to  impregnate the atmosphere, had a disagreeable smell, and produced a difficulty of respiration.

"Fifteen minutes after seven o'clock, we had another shock. This was the most severe one we have yet had -- the darkness returned and the noise was remarkably loud.  The first motions of the earth were similar to the preceding shocks but before it ceased we rebounded up and down, and it was with great  difficulty we kept our seats.  At this instant I expected a dreadful catastrophe - the uproar of the people heightened the colouring of the picture - the screams and yells were heard at a great distance."

The aftershocks lasted into the new year. On 23 January 1812, an earthquake of intensity comparable to the one in December occurred. That one was followed on 7 February by an even stronger earthquake. It is said the Mississippi River even ran backwards briefly, the course of the river was changed and Reelfoot Lake was formed. The aftershocks were numerous, but the three mentioned here were the most severe.

In Jefferson's Nephews  A Frontier Tragedy,  the author, Boynton Merrill Jr., referencing "The Winter the Mississippi River Ran Backwards" by Wayne Viitanten (The Register of the Kentucky Historical Society, Vol. 71, January 1973, 51-68) stated the following:  "The writhing and distortions of the Mississippi River were almost beyond belief. Above New Madrid the river bottom rose and formed a six foot waterfall that stretched entirely across the river. Boats were swept over this barrier until it, in turn, was wiped away by the current. Other boats were tossed about by freak waves that rose thirty feet above the normal water level."

Each of the three main earthquakes in this series have been estimated at a magnitude of over  7.0.  Western Kentucky was not heavily populated and no known deaths were caused by the earthquakes, but how frightened the people must have been!

Earthquake!

At 4:35 this morning and perhaps to commemmorate the 102nd anniversary of the great San Francisco earthquake of 18 Apr 1906, Mother Nature let us know that she has the upper hand in all things weather related. Shaking of buildings accompanied by a loud noise pulled us from our beds and made us wonder if this was the “big one” that has been predicted for the Midwest for years. Fortunately, it was only a 5.2 quake followed by smaller aftershocks. I hesitate to say “only a 5.2” as it might be interpreted as teasing Mother Nature and having her retaliate with an even stronger one.

Keeping this in mind, I tiptoed quietly to the family room, turned on the TV and watched for news of the sleep-shattering event. Everyone agrees that it could have been worse. What if it had been worse? Are we prepared? No, not the food supply; most of us have enough food to keep us from starvation for days. I’m talking about all of the research we have done - our files, CDs, charts, and computer programs. Will they be safe until all systems are restored? If you haven’t done so yet, make copies of your computer programs and files. Store them in safe places - in a bank safety deposit box or with a friend or relative out of town. Scan those charts and documents onto CDs and place them in a safe place too. Think about it. Will your material that took years to gather be wiped out in a brief moment?
