An Earthquake Occurred in the Southern East Pacific Rise on October 9, 2014

The October 9, 2014 Magnitude 7.1 earthquake near the Southern East Pacific Rise occurred as the result of oblique thrust faulting in the complex plate boundary region at the intersection of the Pacific, Nazca and Antarctic plates, nearly 600 km to the south of Easter Island.

At the location of the earthquake, some 100 km to the east of the East Pacific Rise, the Nazca plate diverges from the Pacific at the rate of nearly 15 cm/yr, in a direction slightly south of due east.
