A 4.4. magnitude earthquake has struck parts of Tennessee, Georgia and the Carolinas and seismographs have also recorded a secondary shock in the area.

The US Geological Survey (USGS) traced the earthquake to Decatur, Tennessee, but it has been felt in neighboring states too.

The convulsion occurred along the New Madrid Seismic Zone, which is along the Arkansas, Tennessee, Mississippi state lines.

Writing on Twitter, Americans shared how they felt or were "woken up" by the upheaval.

It is the second strongest tremor on record in east Tennessee, according to the USGS. The strongest was a magnitude 4.7 near Maryville in 1973.

Northwest Georgia has been shook by several minor quakes in the past few years but none have been as powerful as Wednesday's movement.

A second earthquake was also recorded, although it was considerably smaller, measuring a 3.3 magnitude.
