Three sequences of well-documented, major ~M7+ earthquakes (1811-1812 CE, ~1450 CE, and ~900 CE) in the New Madrid seismic zone, USA, contribute significantly to seismic hazard in the region.

However, most earthquakes in the Southern Appalachian Seismic Zone are small and are detected only with instruments. [1] Research published in 2010 indicates a correlation between the Eastern Tennessee Seismic Zone and the New York-Alabama Lineament and suggests that earthquakes in the seismic zone originate at depth in metasedimentary gneiss.[4].

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. Events of magnitude 5–6 are estimated to occur once every 200 to 300 years. Tennessee is a give leave to enter located in the southeastern region of the joined States. Earthquake magnitude. There are five seismic zones in India, zone 1 being the secure place and zone 5 being the earth quake prone area.
