Liquefaction with many Google earth aerial photos. Sandy soil loses its friction, becomes mush with water + force.

FoxNews Jan 2010 update of NM Seismic Zone following a Haiti aftershock. 6 min video
Hidden Fury (click to watch) - a 1993, 27-min video production, now on the web in mpg format. Available from Bullfrog films. Very well produced. Good info, easy to follow, except several experts would now assert the NM 1811-12 quakes were high 7 magnitude, not 8.
The following video clip is not from Hidden Fury.
Strong quakes hit Haiti in Jan 2010. FoxNews then called Gary Patterson, with CERI, Memphis, who summarized the New Madrid Fault. about 4 mins.
Olmsted fault connects New Madrid & Wabash Valley S Indiana faults.
Jack Reed's theory. Reed is a retired geologist who studied oil formations in the Gulf of Mexico. Oversimplified, his theory says a crack in the North American tectonic plate runs from Louisiana through New Madrid to the St. Lawrence Seaway. Seismic activity in the western Gulf of Mexico would directly affect the New Madrid area. Reed2
The Farallon plate swallowed beneath western North America 70 million years ago -- Some say it is still causing the Mississippi valley bumps and grinds.
Centennial history - several notes from eyewitnesses we hadn't seen elsewhere. Note halfway through this piece that many people gathered on Tywappity hill, 30 miles north and 7 miles inland from the river... to seek safety from the shakes. We strongly suspect the hill is now at Lake Tywappity, at the SE edge of Chaffee, MO.

This website is built not to scare you, but to present accurate information. An example of MIS-information comes from Wisconsin [ Jan 08 ], saying a big NM quake would topple factory smokestacks in southern Wisconsin, but the northern part "wouldn't feel a thing."
Rail, air, trucking, and river distribution of goods in Memphis area is key to the nation, and will be disrupted, big-time. Remember that a "catastrophic" quake will probably be a high 7's magnitude. We're overdue for a 6+, which will likely cause some loss of life. Folks in river bottom mud will be worse off than those on the rocky hill, whether in the Missouri River valley, New York State or the eastern seaboard. (River bottom mud amplifies the shake about 6X.) We recommend you maintain a healthy faith walk with your Creator, now.
Is the New Madrid seismic zone "dying"? The question likely won't be answered in your lifetime. It's dying until the next Midwest shake that's felt from Canada to New Orleans, which will start the news media asking, "Has it started again?"
This site has been up for 10 years. Just before Hurricane Katrina, we were getting 35 visitors a day, and thought that was good. Just before the Wabash Valley shakes (low 5 magnitude, north of Evansville IN, Apr 08) that didn't hurt anybody, stats showed we were getting an average 250 a day. On that day it peaked at 20,000 visitors.
We enjoy trying to make the info manageable and comprehendable. We consider the experts to be at CERI, Memphis, SLU-St. Louis, UIUC Champaign, and the list goes on. We appreciate feedback, positive or negative.
Only 35 percent of Missouri homes have earthquake insurance, down from almost 45 percent 10 years ago. The highest concentration of this coverage is in the New Madrid area of the state.
Seventeen insurance companies have ceased writing earthquake coverage in Missouri since 2000; these companies insured over 83,000 homes in Missouri. In that same time period, eight new insurance companies have begun writing earthquake coverage here.
Figures from the Mo state Department of Insurance show less than 38% of home and farm insurance policies included earthquake coverage last year. That's down more than five percentage points from 2001. During that time, the average cost of residential earthquake coverage has risen by more than 15%. Nov 2007 AP / KWMU
Church quake insurance rate once was $30 a year, now $2,500. Waynesville, MO.
Commerce Lineament - a line from Indiana to Arkansas - a gigantic soil blender. It runs 60 miles north of New Madrid, exactly paralleling the New Madrid Fault. Its shakes probably helped reroute the Mississippi River just north of Cairo, IL. It is now (almost) quiet.
Barges pass picturesque Columbus-Belmont (Ky) Park, on a bluff, site of a Civil War struggle. A huge anchor and section of chain at the park shows the south's attempt to close off the river during the war. (The chain broke and sank.)
General Grant had little trouble cutting supplies to rebel troops, and burning a camp at Belmont, Mo., in left of picture. Most maps show the north end of the New Madrid fault about 20 miles west of this point, though some fault lines and quakes continue just north of here (in the distance of photo), through Paducah, Ky. and connect with the Wabash Valley fault near Evansville, IN.
John James Auduborn saw a cloud in the west, when he was 200 miles east of New Madrid. He thought it was a brewing storm cloud. Then his horse sensed a problem. Then he saw dry land undulate like ocean waves.
Several saw earthquake lights in 1811-12 even to the eastern seaboard, at the same time New Madrid was shaking, and even two weeks before the first shake. Other quake lights have been photographed in Japan. There are five theories of their cause.
