A 3.0 is nothin, my sister in-law causes a 3.0 when she gets up to go to the bathroom and have a cookie in the middle of the night!:rolleyes:

Not too far from New Madrid Seismic Zone....The zone had four of the largest North American earthquakes in recorded history, with moment magnitudes estimated to be as large as 8.0, all occurring within a three-month period between December 1811 and February 1812.
snip
Aftershocks were felt every six to ten minutes, a total of 27, in New Madrid until what was called the Daylight Shock, which was of the same intensity as the first. Many of these were also felt throughout the eastern US, though with less intensity than the initial earthquake.

December 16, 1811, the Daylight Shock, 1415 UTC (8:15 a.m.); (M ~7.2 8.2) epicenter in northeast Arkansas; This shock followed the first earthquake by six hours and was similar in intensity.

January 23, 1812, 1500 UTC (9 a.m.); (M ~7.0 8.0) epicenter in the Missouri Bootheel. The meizoseismal area was characterized by general ground warping, ejections, fissuring, severe landslides, and caving of stream banks. Johnston and Schweig attributed this earthquake to a rupture on the New Madrid North Fault. This may have placed strain on the Reelfoot Fault.

February 7, 1812, 0945 UTC (4:45 a.m.); (M ~7.4 8.6) epicenter near New Madrid, Missouri. New Madrid was destroyed. At St. Louis, Missouri, many houses were severely damaged, and their chimneys were toppled. This shock was definitively attributed to the Reelfoot Fault by Johnston and Schweig. It was uplift along this reverse fault segment, in this event, that created waterfalls on the Mississippi River, disrupted the Mississippi River at Kentucky Bend, created a wave that propagated upstream and caused the formation of Reelfoot Lake.

Good point about New Madrid.

That fault area has the potential to be a disaster.

I remember back in the 90's that there was a HUGE freak out that the New Madrid fault was about to go. If an 7-8.0+ earthquake was to happen there, the vast majority of American's would be affected. Thats one I'd probably actually feel.

The one tremor I felt in Detroit (in the 90s) was a rumble along the New Madrid fault. A big quake along that fault could do a lot of damage in some big cities, like Cinncinati, St. Louis, maybe even impact Chicago and Detroit with some damage-it would affect a lot of people. Maybe even more than when "the big one" finally hits southern California.
