Seismological Research Letters (2011) 82 (1): 132–140.
... below Paleozoic rocks. The modeled uplift corresponds to estimates of Paleozoic sediment erosion from the top of the arch. We suggest that faulting accompanied emplacement of the RMA intrusion, establishing a zone of weakness in the upper crust that manifests today as the Reelfoot fault. Faulting...

... the February 7, M 8.0 earthquake when uplift occurred over a distance of 32 km along the Reelfoot Fault scarp. The Lake County uplift and the Reelfoot Fault scarp are within the northwest-trending central arm of the New Madrid Seismic Zone; however, contemporary seismicity in this part of the seismic zone...

Patterson Abstract Previous investigators have argued that the northwest‐striking Reelfoot fault of northwest Tennessee and southeastern Missouri is segmented. One segment boundary is at the intersection...

... fault. By performing probability tests and following different procedures to obtain the result, we show the anomalously high b ‐value is not a processing artifact and is statistically significant. We attribute the b ‐value anomaly to creep behavior on the northern segment of the Reelfoot fault. Creep...

...S. D. Carlson; M. J. Guccione Abstract This study of variability in the amount and rate of deformation along the intraplate Reelfoot fault of the New Madrid seismic zone ( NMSZ ) utilizes diverse research methods, including geophysics, geomorphology, and fluvial sedimentology. The transpressional...

... near Mooring, Tennessee, directly over the Reelfoot fault zone on the afternoon of 16 November 2006. These natural events show up in the shot gathers as near-vertically incident P waves with a dominant frequency of 8–10 Hz and probably occurred at depths of greater than 10 km. The inferred seismicity...

... data obtained from explosive source and Vibroseis® surveys. Interpretation and integration of the three data sets have resulted in a new model for the subsurface of Reelfoot scarp and provide evidence for recurrent movement along Reelfoot fault, the major reverse fault associated with Reelfoot scarp...

...J. N. Baldwin; J. B. Harris; R. B. Van Arsdale; R. Givler; K. I. Kelson; J. L. Sexton; M. Lake Abstract The New Madrid North and Reelfoot Faults are believed to have ruptured during large-magnitude earthquakes on 23 January and 7 February 1812, respectively, based on the regional distribution...

...Ryan Csontos; Roy Van Arsdale Abstract The New Madrid seismic zone of the central Mississippi River valley has been interpreted to be a right-lateral strike-slip fault zone with a left stepover restraining bend (Reelfoot reverse fault). This model is overly simplistic because New Madrid seismicity...

... County uplift, which includes the Tiptonville dome and Ridgely ridge. We believe these structures are a consequence of deformation in the hanging wall above the northwest-striking, southwest-dipping Reelfoot reverse fault. Reelfoot fault dips 73° from the surface to the top of the Precambrian at a depth...

..., herein called the Lilbourn uplift. The uplift appears to be a northwestern extension of the Reelfoot North fault and its hanging wall deformation (the Tiptonville dome). It is not known whether the full length of the Reelfoot fault (70 km) or just the Reelfoot North fault (32 km) ruptured during the 7...

... at this location, a 7.5-km-long seismic reflection profile was acquired on roads along the southern margin of Reelfoot Lake. The seismic line reveals a westerly dipping basin bounded on the west by the Reelfoot reverse fault zone, the Ridgely right-lateral transpressive fault zone on the east, and the Cottonwood...

Significant motions of 0.37±0.07 (one standard error) mm/yr were found between sites PTGV and STLE, for which the baseline crosses the inferred deep portion of the Reelfoot fault. Baselines between STLE and three other...

They duplicated the right-lateral strike-slip movement along the Blytheville Fault zone and New Madrid North Fault, and left-lateral strike-slip movement along the Reelfoot Fault. Due to the two-dimensional nature, however, results of modeling do not show the observed reverse motion...
