Title: Characterizing the geometry and time of deformation of the Meeman-Shelby Fault, near Memphis, TN (NEES-2011-1029)

Year Of Curation: 2013

Description: Despite continuing studies in geodesy, seismology, and paleoseismology in the mid-continent/Mississippi Embayment area, there remains a paradox regarding the documented series of relatively large seismic events and the apparent low rates of deformation. As both modeling and observational studies improve, a variety of approaches are beginning to bear fruit. A promising hypothesis proposed to solve the apparent paradox is that deformation may be focused in different areas at different times, and that the present seismicity might not reflect the long-term behavior of the fault system in the Central US. Mounting evidence, mainly from paleoseismological studies, strongly suggests that the seismicity might have been migrating at least during the Holocene, although specific structures responsible for seismogenic faults other than the NMSZ system are not well documented.
