Another earthquake shook a North Carolina community on Friday, which is reportedly indicative of an old fault line that is now active.
The U.S. Geological Survey told The Charlotte Observer that scientists don’t know if the “cluster” will continue and are not sure why it has suddenly become active.
Friday’s early morning quake was magnitude 2.1 and was centered about four kilometers to the north of West Canton.
There was only one response filed on the USGS website by a person who felt the tremor.
All the recent earthquakes recorded in the area originated near Chambers Mountain.

The USGS reportedly said that while these earthquakes are minor in magnitude, stronger quakes are not impossible.
The agency did not immediately respond to Fox News Digital’s request for comment on Saturday.

Faults may range in length from just millimeters to thousands of kilometers long.
