The main shock occurred at 9:15 am, and its magnitude was estimated at 7.5. Research also indicates that other large earthquakes have occurred in the region surrounding the main New Madrid seismicity trends in the past 5,000 years or so. 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, and the roaring of the Mississippi— the current of which was retrograde for a few minutes, owing as is supposed, to an irruption in its bed— formed a scene truly horrible. In 1811, the population was about 1,000 people made up of farmers, fur traders and pioneers supplemented by French Creoles and Native […] The USGS “concludes that the New Madrid Seismic zone is at significant risk for damaging earthquakes that must be accounted for in urban planning and development. The zone, colored red on the map, is called the New Madrid Seismic Zone. Survivors reported that the earthquakes caused Soil liquefaction caused large sand blows that fouled farmland in Missouri, Tennessee, and Arkansas. I could distinctly see the river as if agitated by a storm; and although the noise was inconceivably loud and terrific, I could distinctly hear the crash of falling trees, and the screaming of the wild fowl on the river, but found that the boat was still safe at her moorings. “They remain the most powerful earthquakes to hit the contiguous United States east of the Rocky Mountains in recorded history.” 1 The three earthquakes and their major aftershocks were: 2 The initial New Madrid quake was between nine and twelve times more powerful than either of them. On the night of 16th November [sic], 1811, an earthquake occurred, that produced great consternation amongst the people. The cattle came running home bellowing with fear, and all animals were terribly alarmed on the occasion. Flatboat operators reported that the flow of the Mississippi River was suddenly reversed; however, scientific studies performed since that time note that the tremors produced northward-moving water waves that gave the illusion that the river reversed its course. The soil … Instead, the new research showed that the strain is continuing to increase in the New Madrid zone, and so the earthquake danger continues to stay high. In recent decades, minor earthquakes have continued. The resulting rift system failed, but has remained as an aulacogen (a scar or zone of weakness) deep underground. The upthrusting of the land some 15 miles (24 km) to the south of the epicentre pushed water into a basin that dropped 5 to 20 feet (1.5 to 6 metres) and created Reelfoot Lake, which is located near Tiptonville, Tennessee. Shortly after the earthquake began, ground shaking was felt as far away as Canada in the north and the Gulf Coast in the south. It is said the shock of an earthquake was felt in Kaskaskia in 1804, but I did not perceive it. On November 6, 1811, Governor Harrison attacked Prophet’s Town with over 1,000 men and this was the beginning of the Tecumseh’s War. They were among the most intense earthquakes in US history and by far the largest to occur east of the Rocky Mountains. Let us know if you have suggestions to improve this article (requires login). Church bells rang in Boston. Only gradually did it reclaim its place as a viable river port town. The New Madrid Earthquakes took place between December 1811 and April 1812 along an active fault line that extends roughly from Marked Tree (Poinsett County) in a northeasterly direction, crossing several states for about 150 miles. Abstract Continental North America's greatest earthquake sequence struck on the western frontier of the United States. Eyewitnesses reported that shaking from this temblor was severe, especially in New Bourbon, Missouri, but not as strong as the main shock. They didn't dare to stop and pick up a few survivors, for fear of being overrun, and they were without supplies. Damage-range comparison between a moderate New Madrid zone earthquake (1895, magnitude 6.8), and a similar Los Angeles event (1994, magnitude 6.7). The unusual seismic activity began at about 2 a.m. on December 16, 1811, when a strong tremor rocked the New Madrid region. The New Madrid Seismic Zone (NMSZ) is made up of reactivated faults that formed when what is now North America began to split or rift apart during the breakup of the supercontinent Rodinia in the Neoproterozoic era (about 750 million years ago). Scholars do agree, however, that the New Madrid earthquakes were the strongest such events recorded in North America east of the Rocky Mountains. In addition, Lake St. Francis in Arkansas, a water body formed by subsidence that followed earlier earthquakes associated with the NMSZ, expanded. Not one in the family knew at the time that it was an earthquake. A repeat of these earthquake-triggered landslides today would affect eastern access to the Mississippi River, pipelines, and transmission towers located in … Residents flee their collapsing cabin in New Madrid, Mo., early on Dec. 16, 1811, during the first of what became known as the New Madrid earthquakes. They found that the town of New Madrid had been destroyed. Tecumseh was at the Shawnee and Delaware Indian villages near Cape Girardeau, 50 miles north of the epicenter at New Madrid, when the first earthquake hit on December 16, 1811. The underlying cause of the earthquakes is not well understood, but modern faulting seems to be related to an ancient geologic feature buried under the Mississippi River alluvial plain, known as the Reelfoot Rift. Save 84% off the newsstand price! In 1811 and 1812, a series of earthquakes emanated from New Madrid, Missouri, and were felt as far away as Ohio and South Carolina. The New Madrid quake is especially intriguing not only because of its unparalleled power, but also because it occurred in an area which is normally devoid of tectonic activity, including earthquakes. The magnitude of the December 16, 1811, event ranged from 6.7 to 8.1, whereas the ranges for the earthquakes of January 23 and February 7, 1812, were 6.8–7.8 and 7.0–8.8, respectively. It was reported that more than 200 moderate to large earthquakes occurred on the New Madrid fault … There were thousands of aftershocks, of which 1,874 were large enough to be felt in Louisville, Kentucky, about 190 miles (300 km) away. On November 6, 1811, Governor Harrison attacked Prophet’s Town with over 1,000 men and this was the beginning of the Tecumseh’s War. Tecumseh was at the Shawnee and Delaware Indian villages near Cape Girardeau, 50 miles north of the epicenter at New Madrid, when the first earthquake hit on December 16, 1811.

The epicenters of the earthquakes were located in an area that at the time was at the distant western edge of the American frontier, only sparsely settled by European pioneers. Our family all were sleeping in a log cabin, and my father leaped out of bed crying aloud "the Indians are on the house" ... We laughed at the mistake of my father, but soon found out it was worse than the Indians. The main section involved was from island 10 northward about 10 miles to island 8. The There are many things that were unusual about the New Madrid earthquakes of 1811-1812. Tree with a double set of roots, formed in the aftermath of the New Madrid earthquakes (1811–12). At 2:15 a.m. on December 16, 1811, residents of the frontier town of New Madrid, in what is now Missouri, were jolted from their beds by a violent earthquake. New Madrid, Missouri was at the back end of nowhere. It was technically a respectably sized town on the Mississippi River between St. Louis and Natchez, but this was not a great achievement. There were temporary river waterfalls where the Mississippi ran backwards during 1811-12 earthquakes. The so-called New Madrid earthquakes–named for a small Missouri settlement near the modern-day borders of Kentucky, Tennessee, Illinois, Indiana, and Arkansas that lay nearest the center of this cataclysmic seismic sequence–are the largest to have struck the eastern United States since well before they became the United States. The Shaker diarist Samuel Swan McClelland described the effects of the earthquake on the Shaker settlement at West Union (Busro), Indiana, where the earthquakes contributed to the temporary abandonment of the westernmost Shaker community.[12]. Updates? Some areas sank, while others were uplifted. Contemporary accounts have led seismologists to estimate that these stable continental region earthquakes were felt strongly throughout much of the central and eastern United States, across an area of roughly 130,000 square kilometers (50,000 sq mi), and moderately across nearly 3 million km2 (1 million sq mi). Like the main shock, however, seismic waves from this event were also felt in cities along the Eastern Seaboard. Despite the strength of the tremors, only minor damage to human-made structures was reported: from collapsing chimneys, falling trees, and cracking timbers in houses. President James Madison and his wife Dolly felt them in the White House. While most earthquakes in Arkansas go unnoticed, our state has experienced several historical earthquakes, including two which caused backward flow of the Mississippi River. (It was discernible as far away as Boston.) The 1811–1812 New Madrid earthquakes (/ ˈ m æ d r ɪ d /) were a series of intense intraplate earthquakes beginning with an initial earthquake of moment magnitude 7.2–8.2 on December 16, 1811, followed by a moment magnitude 7.4 aftershock on the same day. In the first several years of the 1800s, most of our country’s residents lived east of the Mississippi River. The strongest aftershock, a magnitude-7.0 tremor that became known as the “dawn aftershock,” occurred later that day at 7:15 am. Three earthquakes had a magnitude of 7.0 or greater. New Madrid, Missouri was at the back end of nowhere. The earthquakes and their aftershocks took place within a large region called the New Madrid Seismic Zone (NMSZ)—an area of high earthquake risk running from northeastern Arkansas and northwestern Tennessee to southeastern Missouri and southwestern Kentucky. William Leigh Pierce, a literate twenty-one-year-old traveler, was en route to New Orleans on a flatboat in December 1811 when a violent and … Two additional earthquakes of similar magnitude followed in January and February 1812. The shocks continued for years in Illinois, and some have experienced it this year, 1855. traffic helped create a national economy, opening markets for farm goods and drawing people and commerce to cities along the rivers. The main shock that occurred at 2:15 am on December 16, 1811, was a result of slippage along the Cottonwood Grove Fault in northeastern Arkansas. In 1811 and 1812, a series of large earthquakes and aftershocks, in what was then the western frontier of America, occurred in the area of New Madrid, Louisiana Territory (now Missouri). The third principal earthquake, on February 7, however, matched or exceeded the strength and severity of the December 16 event. This would make a total of five earthquakes of magnitude MSn 8.0 or higher occurring in the period December 16, 1811 through February 7, 1812. The Roosevelts and the crew of the New Orleans were about 200 miles from the epicenter on December 16, and they felt the shock distinctly. The number of lives lost from the earthquakes remains unknown; however, scholars note that the number was probably not great, because the region had only a sparse rural population. Eliza Bryan[10] in New Madrid, Territory of Missouri, wrote the following eyewitness account in March 1812: On the 16th of December, 1811, about two o'clock, a.m., we were visited by a violent shock of an earthquake, accompanied by a very awful noise resembling loud but distant thunder, but more hoarse and vibrating, which was followed in a few minutes by the complete saturation of the atmosphere, with sulphurious vapor, causing total darkness. At 2:15 a.m. on December 16, 1811, residents of the frontier town of New Madrid, in what is now Missouri, were jolted from their beds by a violent earthquake. Bicentennial of the 1811-1812 New Madrid earthquake sequence December 2011-2012. They originate from the seismic activity of the Reelfoot Rift. Our house cracked and quivered, so we were fearful it would fall to the ground. River water disturbed by uplift and subsidence also washed out forested areas upstream. The last major shake was on Feb. 7, 1812. Ring in the new year with a Britannica Membership, Possible causes of the New Madrid earthquakes, https://www.britannica.com/event/New-Madrid-earthquakes-of-1811-1812, USGS Earthquake Hazards - The New Madrid Seismic Zone. • December 16, 1811, 8:15 UTC (2:15 am local time): M 7.2–8.2, epicenter in what is now northeast Arkansas. A 25 to 40% chance exists, in a 50-year time span, of a magnitude 6.0 or greater earthquake. Fissures opened in the ground; some were filled with water from the nearby Mississippi River or wetlands, which was later expelled high into the air when the fissures closed. The New Madrid Seismic Zone (/ ˈ m æ d r ɪ d /), sometimes called the New Madrid Fault Line, is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri.. The first in the series of three New Madrid earthquakes occurred 200 years ago today, in the early morning of Dec. 16, 1811, in what was then a sparsely populated town in … New forecasts estimate a 7 to 10 percent chance, in the next 50 years, of a repeat of a major earthquake like those that occurred in 1811–1812, which likely had magnitudes between 7.6 and 8.0. According to New Madrid historian Norma Hayes Bagnall, “It is assumed that most deaths resulting from the New Madrid earthquakes were caused by drowning.” By March 1812, few people remained in the area. The series of New Madrid earthquakes of 1811-1812 was one of the most dramatic natural disasters to strike the North American continent. The main shock that occurred at 2:15 am on December 16, 1811, was a result of slippage along the Cottonwood Grove Fault in northeastern Arkansas. New Madrid Earthquakes 1811-1812. [1][2][3] The earthquakes, as well as the seismic zone of their occurrence, were named for the Mississippi River town of New Madrid, then part of the Louisiana Territory and now within the U.S. state of Missouri. The centre of the violence was in New Madrid, Missouri, but the whole valley of the Mississippi was violently agitated. 400 terrified residents in the town of New Madrid, Missouri were abruptly awakened by violent shaking and a tremendous roar. The location of the earthquake’s epicentre is controversial, but it is thought to have been located in the vicinity of New Madrid, Missouri, along a fault that runs perpendicular to the Reelfoot Fault. In the New Madrid region, the earthquakes dramatically affected the landscape. Damage to the landscape included the warping of the ground through subsidence (sinking) and uplift, sand blows, ground cracking, landslides, and stream bank calving. A repeat of these earthquake-triggered landslides today would affect eastern access to the Mississippi River, … The 1906 San Francisco earthquake, by comparison, was felt moderately over roughly 16,000 km2 (6,200 sq mi). Reelfoot Lake, near Tiptonville, Tennessee. A quarter century later, just 450 people lived in New Madrid. A seismic seiche propagated upriver, and Little Prairie (a village that was on the site of the former Fort San Fernando, near the site of present-day Caruthersville, Missouri) was heavily … The New Madrid earthquakes caused extensive landsliding along about 125 miles of the bluffs on the east side of the Mississippi River north of Memphis. U.S. Pres. While not as well known for earthquakes as California or Alaska, the New Madrid Seismic Zone (NMSZ), located in southeastern Missouri, northeastern Arkansas, western Tennessee, western Kentucky and southern Illinois, is the most active seismic area in the United States, east of the … Picture and story courtesy of USGS. The next morning another shock made us acquainted with it, so we decided it was an earthquake. [13] The epicenters of over 4,000 earthquakes can be identified from seismic measurements taken since 1974. By the time we could get to our fire, which was on a large flag in the stern of the boat, the shock had ceased; but immediately the perpendicular banks, both above and below us, began to fall into the river in such vast masses, as nearly to sink our boat by the swell they occasioned ... At day-light we had counted twenty-seven shocks. Faults were created along the rift and igneous rocks formed from magma that was being pushed towards the surface. [4], The many more aftershocks include one magnitude 7 aftershock to the December 16, 1811, earthquake which occurred at 6:00 UTC (12:00 am local time) on December 17, 1811, and one magnitude 7 aftershock to the February 7, 1812, earthquake which occurred on the same day at 4:40 UTC (10:40 pm local time). Since the rocks in the eastern United States have few active faults to interrupt the propagation of seismic waves, ground vibrations from earthquakes generated in the region may travel thousands of miles. Only gradually did it reclaim its place as a viable river port town. The historic 1811-1812 earthquakes of New Madrid, Missouri. He serves currently as the editor of Earth and life sciences, covering climatology, geology, zoology, and other topics that relate to... Get a Britannica Premium subscription and gain access to exclusive content. Eyewitness accounts noted that the shaking rang church bells as far away as Boston, Massachusetts, and brought down chimneys in Cincinnati, Ohio, about 360 miles (580 km) away. On the Mississippi River itself, the shaking calved the soil along riverbanks and caused trees lining the river to fall into the water. Corrections? The extent of the area that experienced damaging earth motion, which produced Modified Mercalli Intensity greater than or equal to VII, is estimated to be 600,000 square kilometers. Earthquake of December 16, 1811. [8], John Bradbury, a fellow of the Linnean Society, was on the Mississippi on the night of December 15, 1811, and describes the tremors in great detail in his Travels in the Interior of America in the Years 1809, 1810 and 1811, published in 1817:[9]. St. It was followed by at least three large aftershocks with magnitudes that ranged from 6.0 to 7.0 over the course of the next 48 hours. John Reynolds (1788–1865), the fourth governor of Illinois, among other political posts, mentions the earthquake in his biography My Own Times: Embracing Also the History of My Life (1855):[11]. Unlike those two earthquakes, the New Madrid quake of 1811 caused relatively little loss of life—but only because, in 1811, the Mississippi Valley was sparsely settled. The New Madrid earthquakes caused extensive landsliding along about 125 miles of the bluffs on the east side of the Mississippi River north of Memphis. The New Madrid earthquakes were interpreted variously by American Indian tribes, but one consensus was universally accepted; the powerful earthquake had to have meant something. [3] Susan Hough, a seismologist of the United States Geological Survey (USGS), has estimated the earthquakes' magnitudes as around magnitude 7. In the American Bottom many chimneys were thrown down, and the church bell in Cahokia sounded by the agitation of the building. On December 16, 1811, a major earthquake occurred with its epicenter in the town of New Madrid (now in the state of Missouri). The epicentre of the aftershock is a matter of some debate; some Earth scientists noted that it was located in northeastern Arkansas, whereas others maintained that it was located in northwestern Tennessee near the southern end of the Reelfoot Fault, a large fault running northwest-southeast within the Reelfoot Rift. Two additional earthquakes of similar magnitude followed in January and February 1812. Omissions? New Madrid Earthquakes of 1811-1812. For many tribes in Tecumseh's pan-Indian alliance, it meant that Tecumseh and his brother the Prophet must be supported. The future location of Memphis, Tennessee, experienced level IX shaking on the Mercalli intensity scale. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. Ponds of water also were agitated noticeably. 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. Large waves formed on the water that capsized numerous boats and thrust others onto the land. According to New Madrid historian Norma Hayes Bagnall, “It is assumed that most deaths resulting from the New Madrid earthquakes were caused by drowning.” By March 1812, few people remained in the area. The shock, whose epicentre was also located near New Madrid, Missouri, shook the region at 3:45 am and resulted in the destruction of New Madrid. These eyewitness accounts give a glimpse at what was seen and experienced by people as the earthuquakes occurred. Our editors will review what you’ve submitted and determine whether to revise the article. Other scholars maintain that the weakening of Earth’s crust in this area was caused by downcutting (or river incision) of the Mississippi River between 10,000 and 16,000 years ago. The First Earthquake. Local uplifts of the ground and water waves moving upstream gave the illusion that the river was flowing upstream. It happened when a thrust fault created a sudden dam several feet high near the bottom of the river loop near New Madrid. [14], In a report filed in November 2008, the U.S. Federal Emergency Management Agency warned that a serious earthquake in the New Madrid Seismic Zone could result in "the highest economic losses due to a natural disaster in the United States", further predicting "widespread and catastrophic" damage across Alabama, Arkansas, Illinois, Indiana, Kentucky, Mississippi, Missouri, and particularly Tennessee, where a 7.7 magnitude quake or greater would cause damage to tens of thousands of structures affecting water distribution, transportation systems, and other vital infrastructure.[15]. The city of New Madrid, located near … The implication is that this monster quake originated far deeper in the North American crust than is usual for an earthquake. They caused bank failures along the Mississippi River, landslides along Chickasaw Bluffs in Kentucky and Tennessee, and uplift and subsidence of large tracts of land in the Mississippi River floodplain. First, their location is a surprise. The January 23 event was the smallest of the three principal earthquakes. The first earthquake caused only slight damage to man-made structures, mainly because of the sparse population in the epicentral area. In 1811, the population was about 1,000 people made up of farmers, fur traders and pioneers supplemented by French Creoles and Native […] From December 16, 1811 through March of 1812 there were over 2,000 earthquakes in the central Midwest, and between 6,000-10,000 earthquakes in the Bootheel of Missouri where New Madrid is located near the junction of the Ohio and Mississippi Rivers. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. They remain the most powerful earthquakes to hit the contiguous United States east of the Rocky Mountains in recorded history. Some of the most severe earthquakes in the United States occurred not on the Pacific Coast but in the middle of the continent in southeastern Missouri near the town of New Madrid. The unusual seismic activity began at about 2 a.m. on December 16, 1811, when a strong tremor rocked the New Madrid region. Structural damage also occurred in St. Louis, Missouri, where several chimneys fell because of the ground vibration. The 1811–1812 New Madrid earthquake sequence was preceded by at least two other similar sequences in about A.D. 1450 and A.D. 900. EARTHQUAKES, 1811-12 Description of the New Madrid Earthquake courtesy of The Tennessee Historical Society Between mid-December 1811 and mid-March 1812 a series of catastrophic earthquakes shook West Tennessee and the rest of the Central Mississippi Valley. Scholars do agree, however, that the New Madrid earthquakes were the strongest such events recorded in North America east of the Rocky Mountains. A quarter century later, just 450 people lived in New Madrid. By Kimberly Ruble Sources: John P. Rafferty writes about Earth processes and the environment. It was technically a respectably sized town on the Mississippi River between St. Louis and Natchez, but this was not a great achievement. Magnitude estimates for each of the three events associated with the 1811–12 earthquake sequence vary widely, largely because they rely on historical accounts and analyses of the present-day landscape rather than data provided by modern seismic instrumentation. More-precise figures have been presented by the United States Geological Survey (USGS) Earthquake Hazards Program: magnitude 7.7 for the December earthquake and magnitudes 7.5 and 7.7 for the January and February earthquakes, respectively. It was December 16, 1811, and it was the first of at least three very large (M7 or greater) earthquakes and thousands of aftershocks to rock the regionthat winter, with the last occurring on February 7, 1812. The 1811-12 New Madrid Earthquakes in Neighboring Missouri. First posted September 30, 2011. New Madrid earthquakes of 1811–12, series of three large earthquakes that occurred near New Madrid, Missouri, between December 1811 and February 1812. From time to time, pressure from the movement of tectonic plates causes movement on this weak area resulting in earthquakes. The name has proven apt, for New Madrid by happenstance marks the intersection of three of the six fault segments currently illuminated by microseismicity and believed to be rupture planes of the principal 1811-1812 earthquakes. Thousands of trees were floating on the waters of the Mississippi as they approached New Madrid on December 19th, three days after the earthquake. Shortly after 2 o'clock on the morning of December 16, 1811, the Mississippi River valley was convulsed by an earthquake so severe that it awakened people in cities as distant at Pittsburgh, Pennsylvania, and Norfolk, Virginia.
