The United States Geological Survey estimates that earthquakes as large as magnitude 7.5 are possible in the ETSZ. Even though Oak Ridge, Tennessee experiences these earthquakes, the nuclear reactors in the city are rated to handle 8.0 magnitude earthquakes. So, if a 7.5 magnitude earthquake were to occur, a meltdown would be highly unlikely.
Geological formations in Tennessee largely correspond with the state's topographic features, and, in general, decrease in age from east to west. Most of the Blue Ridge Mountains in the east were formed during the Precambrian era, and contain the state's oldest rocks, igneous strata that is more than 1 billion years old.
The Mississippi River as well as the Tennessee and Cumberland Rivers formed and cut deep into the valleys. The Nashville Basin , which in reality is a geologic dome , was pushed up from underneath by a mantle plume , exposing softer strata that with additional erosion on the Highland Rim surrounding the basin expanded the size of the basin.
This is a list of all tripoints in which the boundaries of three (and only three) U.S. states converge at a single geographic point. Of the 60 such points, 36 are on dry land and 24 are in water. [1]

The physiographic regions of the contiguous United States comprise 8 divisions, 25 provinces, and 85 sections. [1] The system dates to Nevin Fenneman's report Physiographic Divisions of the United States, published in 1916. [2] [3] The map was updated and republished by the Association of American Geographers in 1928. [4]
Module:Location map/data/USA Tennessee is a location map definition used to overlay markers and labels on an equirectangular projection map of the U.S. state of Tennessee. The markers are placed by latitude and longitude coordinates on the default map or a similar map image.
