Science Behind the 2020 Sparta, North Carolina Earthquake

In August 2020, the town of Sparta, North Carolina experienced a magnitude 5.1 earthquake, the largest earthquake seen in the area since 1916. This region is nowhere near a plate boundary where we see the most earthquakes. So why does this area get earthquakes despite being so far away from these boundaries? To find out we go back in time hundreds of millions of years ago when continents were colliding.
