Faults cover this entire earth. However, there is one in particular that is relevant to a region we are living close to today, and this is the Reelfoot fault. This fault starts at the bluffs of Reelfoot Lake in Tennessee. Then, it spreads south to the Mississippi River levee, north to the Kentucky Bend, and west to New Madrid, Missouri. This fault ultimately aligns the New Madrid Seismic zone, and it is a reverse fault. A reverse fault is when a hanging wall slides up a footwall. This is a type of convergent boundary where two plates compress together. The New Madrid Seismic zone is known historically for a series of earthquakes in 1811 and 1812. The first earthquake occurred in Northeast Arkansas with a magnitude of 7.5. This was on December
