The June 17, 2015 M 7.0 Southern Mid-Atlantic Ridge earthquake occurred as the result of left-lateral strike-slip faulting on or near a transform fault forming part of the South America: Africa (Nubia) plate boundary. At the latitude of this earthquake, the South America plate moves approximately westward at the rate of 33 mm/yr with respect to Nubia. While the historic earthquakes have occurred in the same region, and may occur in the same structure as this earthquake, the fracture zone does not appear to be named.
