SPARTA, N.C. — Monday marked one year since a magnitude 5.1 earthquake struck near Sparta, North Carolina.

The earthquake caused a road to buckle in Gap Civil, North Carolina, and caused bricks to separate from homes along Little River Drive.
Experts said the quake was the result of an oblique-reverse fault. They form when compressional forces cause a fault plane to move sideways, creating an earthquake.

Experts also said last summer’s quake was a rare type of event for the area.
The earthquake happened about six miles underground, classifying it as a shallow tremor.
Deeper earthquakes tend to be felt less at the surface because of their depth.
