Since the 7th of October there have been 7 "small" quakes in the AR area. Earthquake List for 10-degree Map Centered at 35°N, 90°W Earthquakes in my area are not common, but do happen. Real Foot lake was formed from an earthquake that caused the Mississippi river to flow backwards, for up to a week I think. I'll have to check the time line on it. When the "new madrid" quake hit church bells rang on the east coast. I can't imagine what the damage would be like if the same strength of quake hit today. Unfortunately my wife works very close to the Mississippi river, in an area that is a "liquefaction zone". Our house is just outside the liquefaction zone, and where I work, the building is on solid bed rock (or so I've been told).
