Why does the New Madrid Fault exist?

The Reelfoot rift is identified today as a subsurface system of fractures and faults in the earth’s crust. New Madrid seismicity is spatially associated with the Reelfoot rift and may be produced by movement on old faults in response to compressive stress related to plate motions.
