Interesting geological effects, check out the quartz crystal luminescence:
"The world's largest sand boil was created by the New Madrid earthquake. It is 1.4 miles long and 136 acres in extent, located in the Bootheel of Missouri, about eight miles west of Hayti, Missouri. Locals call it "The Beach." Other, much smaller, sand boils are found throughout the area.
Seismic Tar Balls; Small pellets up to golf ball sized tar balls are found in sand boils and fissures. They are petroleum that has been solidified, or "petroliferous nodules.”
Earthquake Lights; Lights flashed up from the ground, caused by quartz crystals being squeezed. The phenomena is called “seismoluminescence.""
Powerful earthquake:
"The area of strong shaking associated with these shocks was two to three times larger than that of the 1964 Alaska earthquake and 10 times larger than that of the 1906 San Francisco earthquake. The midwest experienced more than 2,000 earthquakes in five months, people discovered that most of crevices opening up during an earthquake ran from north to south and they would chop down trees in an east- west direction using the trees as a bridge. There were "missing people" who were most likely swallowed up by the earth. Some earthquake fissures were as long as five miles."
Long lasting and reached far:
" The New Madrid earthquakes were the biggest earthquakes in American history. They occurred in the central Mississippi Valley, but were felt as far away as New York City, Boston, Montreal, and Washington D.C. President James Madison and his wife Dolly felt them in the White House. Church bells rang in Boston. From December 16, 1811 through March of 1812 there were over 2,000 earthquake aftershocks 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.
In the known history of the world, no other earthquakes have lasted so long or produced so much evidence of damage as the New Madrid earthquakes. Three of the earthquakes are on the list of America's top earthquakes: the first one on December 16, 1811, a magnitude of 8.1 on the Richter scale; the second on January 23, 1812, at 7.8; and the third on February 7, 1812, at as much as 8.8 magnitude."
