Additional Commentary

The November 25, 2013 M7.0 earthquake (06:27:33 UTC) southwest of the Falkland Islands in the South Atlantic Ocean occurred as the result of strike slip faulting, on either a left-lateral fault striking ENE-WSW, or a right-lateral structure striking NNW-SSE.  The location of the earthquake, near the ENE-WSW trending plate boundary between the South America and Scotia tectonic plates, suggests it is likely associated with left-lateral faulting along this margin. At the location of this earthquake, the Scotia plate moves ENE with respect to South America at a rate of approximately 9.5 mm/yr.
The November 25, 06:27:33 earthquake was the largest of 5 M5+ events that occurred in a similar area over an approximate 2-hour period, including a M5.6 earthquake 24 seconds prior to the M7.0 mainshock. Though this region experiences moderate-sized earthquakes relatively frequently – 15 M5+ events have occurred within 250 km of the November 25 earthquake over the past 40 years – large events are fairly uncommon. The largest nearby earthquake over the same time period was a M6.6 event in September 1993, 210 km to the east of the November 25 earthquake.
