When the Mississippi flowed again

Tectonic occasions like a 5.8 earthquake in California and a volcanic eruption in Washington caught our consideration. However they did not match the New Madrid earthquakes of December 1811 in February. 1812 that brought about the mighty Mississippi River to briefly stream backwards.

Think about the witness assertion of Firmin La Roche, a French fur dealer from St. Louis.

The frontier west of the Mississippi had been bought by France to america simply eight years earlier than the earthquake. Missouri was a territory, not but a state.

LaRoche’s account – preserved within the archives of the Missouri Historic Overview – was written in New Orleans on February 20, 1812, when replicas had been nonetheless frequent. He had simply accomplished a disastrous journey that started with three irons:

It seems like thunder

“I used to be current on the earthquake which occurred these days above and beneath the mouth of the Ohio River, alongside each banks of the Mississippi River.

“I used to be taking three boats for New Orleans with some skins purchased in St. Louis. On the night of the fifteenth of December, we tied up eight miles north of New Madrid close to the home of my cousin, John LeClerq.

“There was with me Fr. Joseph of the Mission to the Osages, returning house to France, additionally Jacques Menier, Dominic Berges, Leon Sarpy, Henry Lamel, 5 different males, and the negro slave, Ben, who was killed in New. Madrid.

“After dinner we went to sleep. I used to be woke up by a crash like thunder. The boat turned on its aspect in order that Lamel, who was sleeping on the aspect, threw me on high of me. We fell on our sides. It was very darkish .

“We obtained away from the financial institution in about half an hour and I checked out my watch. It was 3 o’clock. I noticed timber falling on the financial institution. Massive plenty of earth fell into the river.

“Lamel reduce the rope that sure us to a log. At one level a wave so nice got here up the river that I by no means noticed one prefer it at sea. It carried us north, upriver, for greater than a mile The water unfold over the banks, protecting three or 4 miles inland.

“It was a present going backwards. Then that wave stopped and step by step the river went proper once more.

“In all places there was a noise like thunder. The bottom shook the timber. The air was thick with one thing like smoke. There was numerous lightning.

“We thought we should absolutely die. Fr. Joseph gave the absolution. We didn’t see both of the opposite two ships. We by no means noticed one among them once more, nor do I do know if the lads on it left drown. We had been all in nice terror, ready for demise.

“Bushes had been blown down. Individuals mentioned massive cracks within the floor, some very deep, extending 10 or 15 miles. “We had been informed there’s a new lake in Tennessee (Reelfoot) and that the programs of water have been modified. The Yazoo River has a brand new mouth.

“I used to be in nice ache with a damaged arm. Of those that had been with me there may be none however Father Joseph. My private loss is $600 (about $12,000 in at present’s forex).

Memoir of a priest

In an appendix to La Rouche’s account, Father Joseph acknowledged:

“I believe there have been two nice shocks about half an hour aside and lots of small ones between and after. The water rose so {that a} tree on the financial institution, the highest of which should have been 30 ft above the extent of the river, it was lined in every single place. .

“We noticed two homes on fireplace on the left financial institution. After we obtained to Nou Madrid, there have been additionally homes burning.

“We tied as much as the shore about daybreak, and a walnut tree fell on the boat, killing the negro, Ben, and breaking the left arm of skipper LaRouche.

“We made no effort to learn how many individuals had died, though we had been informed there have been many. We noticed the lifeless our bodies of a number of. Then we noticed drowned folks floating within the river.

“Carloads of skins had been thrown into the river by the individuals who crowded into the boat with us till we might maintain no extra.”

One other account

One other eyewitness (edited right here for brevity) was deposed by New Madrid resident Eliza Bryan 4 years after the occasion.

“On the sixteenth of December, 1811, about 2 o’clock within the morning, we had been visited by a violent shock of an earthquake. It was accompanied by a really horrible noise resembling loud however distant thunder, however extra hoarse and vibration

“This was adopted in a couple of minutes by the entire saturation of the environment with sulphurous vapour, inflicting complete darkness.

“Actually horrible had been the cries of the frightened inhabitants who ran from side to side, not figuring out the place to go, what to do—the cries of birds and beasts of all types—the crackling of falling timber—and the roar of the mississippi.which was retrograde for a couple of minutes.

“The inhabitants fled in all instructions, supposing that there was much less hazard at a distance than close to the river.

“There have been a number of lighter shocks each day till January 23, 1812. Then occurred one as violent as probably the most critical of the previous.

“From this time till the 4th of February, the earth was in continuous agitation, visibly tossing like a mild sea.

“On the seventh of February, at about 4 o’clock within the morning, a way more violent concussion passed off than these which had produced it, which was referred to as ‘the onerous shock.’

“The horrible darkness of the environment saturated with sulphurous vapour, and the violence of the stormy noise of thunder, shaped a scene past creativeness.

“At first the Mississippi appeared to recede from its banks, its waters massed like a mountain. For a second many a ship sure for New Orleans lay upon the naked sand. The poor sailors escaped from ‘they.

“Then the river rose 15 to twenty ft perpendicularly and expanded. The banks overflowed with the retrograde present. Boats that had been mendacity on the sand had been now torn from their moorings.

“The river, falling as shortly because it had risen, carried away whole groves of cottonwood timber. Many fish had been left on the banks.

“In all of the sturdy shocks, the earth was horribly damaged into items. A whole lot of hectares had been lined by the sand that got here out of the fissures. In some locations, there was a substance just like coal.

“It has these days been found {that a} lake (Reelfoot) was shaped on the alternative aspect of the Mississippi within the Indian nation (west of Tennessee). It’s greater than 100 miles lengthy, one to 6 miles vast, and a depth from 10 to 50. ft.

“For eighteen months, we had been confined by the worry that our homes would fall from the fixed shocks, and so we lived in small and lightweight camps. Some folks fled, by no means to return, however most returned to the drift”.

Earth’s big fault

The US Geological Survey calls the three main earthquakes within the central Mississippi Valley within the winter of 1811-12 “probably the most highly effective in US historical past”.

There have been no seismographs then. Nevertheless, the extent of the bottom modifications signifies three intently associated earthquakes: magnitudes of 8 or larger on the ten-point Richter seismograph scale.

The strongest earthquake on report is the 8.4 Richter for the 1964 Alaska earthquake.

USGS says: “Earthquakes within the central United States have an effect on a lot bigger areas than earthquakes of comparable magnitude within the western U.S.

“The 1906 San Francisco, California earthquake (magnitude 7.8) was felt 350 miles away. The primary New Madrid earthquake rang church bells in Boston, Massachusetts, a thousand miles away “.

New Madrid in 1811 consisted of 400 log cabins. San Luis and Memphis had been small cities. “If a magnitude 8 earthquake struck at present, these cities could be largely destroyed and hundreds of individuals would die,” the USGS says.

Final yr, 470 measurable earthquakes had been recorded within the Central Mississippi Valley.

USGS warning: “The likelihood of a magnitude 6 to 7 earthquake occurring within the New Madrid Seismic Zone within the subsequent 50 years is bigger than 90 %.”


What’s worse: hurricanes, tornadoes, floods, wildfires, mudslides, volcanoes, or earthquakes?
