The probability for an earthquake of magnitude 6.0 or greater is significant in the near future, with a 50% chance by the year 2000 and a 90% chance by the year 2040. A quake with a magnitude equal to that of the 1811- 1812 quakes could result in great loss of life and property damage in the billions of dollars. Scientists believe we could be overdue for a large earthquake and through research and public awareness may be able to prevent such losses
Los Angeles can expect to be mightily damaged by movement on the San Andreas Fault, or the Newport-Inglewood or other neighboring faults, most probably within the next 25 years. But the Eastern and Midwestern states also face ground shaking of colossal proportions, repetitions of such known upheavals as the 1886 Charleston, S.C., quake, the 1755 Boston quake, and the Jamaica Bay quake hundreds of years ago on New York's Long Island. The granddaddy of them all was the 1811-1812 series of three great quakes on the New Madrid Fault (halfway between St. Louis and Memphis beneath the Mississippi), which shook the entire United States. The next time the New Madrid Fault produces such a quake, it is estimated 60 percent of Memphis will be devastated, leaving $50 Billion in damage and thousands of dead in its wake. Memphis, you see - like Armenia - has looked down the barrel of a loaded seismic gun for decades, but has done virtually nothing to move out of the crosshairs.

New Madrid Earthquakes 1811-1812
New Madrid 1811-1812 Earthquakes
http://en.wikipedia.org/wiki/New_Madrid_Earthquake
The New Madrid Earthquake, one of the largest earthquakes ever recorded in the contiguous United States, occurred on February 7, 1812. It got its name from its primary location in the New Madrid Seismic Zone, near New Madrid, Louisiana Territory (now Missouri).
This earthquake was preceded by three other major quakes: two on December 16, 1811, and one on January 23, 1812. These earthquakes destroyed approximately half the town of New Madrid. There were also numerous aftershocks in the area for the rest of that winter.
There are estimates that the earthquakes were felt strongly over 50,000 square miles (130,000 km˛), and moderately across nearly one million square miles. The historic San Francisco earthquake of 1906, by comparison, was felt moderately over 6,000 square miles (16,000 km˛

The Mississippi Valley-"Whole Lotta Shakin' Goin' On"
In the winter of 1811-12, the central Mississippi Valley was struck by three of the most powerful earthquakes in U.S. history. Even today, this region has more earthquakes than any other part of the United States east of the Rocky Mountains. Government agencies, universities, and private organizations are working to increase awareness of the earthquake threat and to reduce loss of life and property in future shocks.

The Granddaddy Quake - Feb. 1812
Perhaps the biggest quake came two weeks later, in the early hours of February 7th, 1812. The dip-slip motion may have produced the strongest quake ever recorded in the United States.

On December 16, 1811, the 400 residents of New Madrid, Missouri, were shaken out of their beds at two in the morning by a violent earthquake. Huge cracks split the ground. The waters of the Mississippi rose and fell like a great tide. Giant waves rose up and swept north, giving the impression that the river was actually flowing backwards. Boats along the river were engulfed, capsized, and theeair crews drowned.
The “New Orleans” was one of the lucky ones. The first steamboat to ply the Mississippi River, she was embarked on her maiden voyage. At dusk she tied up at an island in the middle of the stream. Then, in the wee hours, the boat was nearly swamped by a series of enormous waves. As the deck pitched and yawed, the crew and the few passengers on board held on for their lives. Later, one of the crew said it was like being in the middle of an ocean during a violent storm.
All along the riverbank, high bluffs crumbled into the water. Seemingly solid ground undulated in waves. Old river channels slammed shut and new ones opened, changing the course of the stream forever. One large lake had its water suddenly replaced by sand. Another lake, Reelfoot, was created in a matter of moments.
Trees toppled or were drowned when the land sank suddenly beneath them. Log cabins scattered like match sticks in New Madrid but, luckily, only one person was killed by falling debris.
Effects of the quake were widespread. Damage was reported as far east as Charleston, South Carolina and Washington, DC. In Boston, Massachusetts, 1,000 miles away, church bells were made to ring. The effects of the quake were felt as far south as New Orleans and as far north as Canada.
The gigantic shake in the early morning of December 16 was only the first in a series of four. There was a second shock hours later. A third quake rocked the area on January 23 and a fourth -- the biggest of all -- was felt on February 7. Between the major quakes, there were thousands of aftershocks.
It is not known how many were killed or injured in the New Madrid Earthquakes, but casualties were probably light. In 1811-1812, the area was sparsely

Some scientists claim that the so-called “Big One” will not happen on the West Coast at all. Rather, a surprising number of them argue that the next sizable shake might occur along the New Madrid Fault, probably by the year 2010. Other authorities, like The Central United States Earthquake Consortium, say there is a 90 percent chance of a magnitude six or seven earthquake hitting the Mississippi Valley within the next 50 years
The New Madrid Fault extends from eastern Arkansas to about the junction of the Mississippi and Ohio Rivers. It is called a failed rift -- that is, a fault not located near one of the several large tectonic plates that float on the hot mantle of the earth. Most earthquakes -- like those in California and Japan -- occur where the plates grind past each other. The geology in these earthquake zones is different. The ground here is warmer from the heat coming from inside the earth -- somewhat elastic. Not so at New Madrid.
Here the ground is cold and brittle. When it moves, there is no elasticity so there is more widespread damage. A sizable quake, such as the ones in 1811-1812, would cause extensive devastation and loss of life. The cities of Memphis, Tennessee, and St. Louis, Missouri would be hit head-on. There would be enormous damage in Kentucky, Ohio, Illinois, Arkansas, Indiana and Mississippi. Yet, some people in these areas are barely aware that the possibility of a major earthquake exists.
However, there are voices crying in the wilderness and they are beginning to be heard. In 1983, at the urging of the USGS, the states of Arkansas, Illinois, Indiana, Kentucky, Mississippi and Tennessee formed the Central United States Earthquake Consortium (CUSEC). The organization is currently embarked on an intensive program of public education and awareness. Through their urging, for instance, earthquake education is now included in the curriculum of public schools in many CUSEC states.
