1812 New Madrid earthquake -wiki
Consequence of the 1811-12 earthquakes
Some sections of the Mississippi River appeared to run backward for a short time.[3] Sand blows were common throughout the area, and can still be seen from the air in cultivated fields. The shockwaves propagated efficiently through the firm midwestern bedrock, with residents as far away as Pittsburgh, Pennsylvania, and Norfolk, Virginia, awakened by intense shaking.[9] Church bells were reported to ring as far as Boston, Massachusetts and York, Ontario (now Toronto), and sidewalks were reported to have been cracked and broken in Washington, D.C.[10] There were also reports of toppled chimneys in Maine.
