In the United States, a large earthquake tore down building in the late 1800 in Charleston, SC; the Eastern Tennessee Seismic Zone sees atleast a thousand small earthquakes each year; and the largest earthquake in the continental U.S. occurred along the New Madrid fault near St. Louis, Missouri in … You can be assured our editors closely monitor every feedback sent and will take appropriate actions. "I think we've got a pretty good case that this is related to active faulting, and that it does demonstrate that at least in periods of time in the past there have been strong earthquakes in the ETSZ," said Cox. Reproduction Date: The Eastern Tennessee Seismic Zone (ETSZ), also known as the East Tennessee Seismic Zone and the Southern Appalachian Seismic Zone, is a geographic band stretching from northeastern Alabama to southwestern Virginia that is subject to frequent small earthquakes.

Seismicity in the central and eastern United States consists of a low background level and several distinct zones, such as the eastern Tennessee and New Madrid seismic zones. John Bellini, a geophysicist with USGS, said “there is a history of earthquakes” in the Eastern Tennessee Seismic Zone, which extends into northwest Georgia and northeast Alabama. Due to proximity to the New Madrid fault line, most structures in Memphis are retrofitted to withstand earthquakes, but homes and buildings in Middle Tennessee generally do not have such prerequisites and likely will not need them. "The ETSZ is right along the Smoky Mountains, which are a subrange of the Appalachians," Cox said. WHEBN0017181125 Earthquakes associated with the ETSZ have included: Hampton Roads, Washington, D.C., Richmond, Virginia, Norfolk, Virginia, American Civil War, Montgomery, Alabama, Mobile, Alabama, Birmingham, Alabama, Auburn University, Mississippi, Tennessee, Knox County, Tennessee, Democratic Party (United States), City, Tennessee Valley Authority, Geology of Chile, Rocky Mountains, Seismology, Knoxville, Tennessee, List of earthquakes in 2003, Montgomery, Alabama, Alabama, Auburn University, Mobile, Alabama, Autauga County, Alabama, Cretaceous, Ordovician, Tennessee, Mississippi Embayment, Devonian, /ia, /ia (U.S. state), Atlanta, Blue Ridge Mountains, Coal, Canada, United States, Lake Erie, Lake Ontario, Basin and Range Province, Canada, Alaska, Northern Cordilleran Volcanic Province, North America, British Columbia, . Randel Cox of the University of Memphis and colleagues searched for signs of ancient earthquakes below the muddy waterline of Douglas Lake, a 1943 Tennessee Valley Authority lake created by impounding the French Broad River. At one site, a thrust fault with one meter displacement suggests that one of the earthquakes could have been magnitude 6 or even larger.

MORE: Here are the most powerful Tennessee earthquakes from the last 100 years Masonry brick-and-mortar buildings are the most likely to sustain significant damage if tremors reach the Nashville area. or, by Seismological Society of America. A few damaging earthquakes have occurred in the ETSZ; the largest historic earthquakes measured 4.6 magnitude, occurring in 1973 near Knoxville, Tennessee and April 29, 2003 near Fort Payne, Alabama. The known faults in the ETSZ are generally ancient; no known active faults reach the surface. The Eastern Tennessee Seismic Zone (ETSZ), also known as the East Tennessee Seismic Zone and the Southern Appalachian Seismic Zone, is a geographic band stretching from northeastern Alabama to southwestern Virginia that is subject to frequent small earthquakes.

In the East Tennessee Seismic Zone, there have been 188 earthquakes of magnitude 2.5 or greater since measurements began in the 1970s. The Eastern Tennessee Seismic Zone (ETSZ) is one of the most active areas in the southeastern U.S. Its known faults are generally ancient and no known active faults reach the surface. Post-ice age sediments, which might tell us more about the current potential for large earthquakes in the region, are mostly underwater as a result of Tennessee Valley Authority projects, Cox added.
