Tectonic Summary

The September 28, 2013 M6.8 earthquake in south-central Pakistan occurred as the result of oblique-strike-slip motion at shallow crustal depths. This earthquake is an aftershock located approximately 30 km to the north-northeast of the September 24, 2013 M7.7 event, which struck with a similar faulting mechanism. As with the September 24 event, the September 28 earthquake mechanism and location are consistent with rupture within the Eurasia plate above the Makran subduction zone. The event occurred within the transition zone between northward subduction of the Arabia plate beneath the Eurasia plate and northward collision of the India plate with the Eurasia plate. … Makran subduction zone has produced large devastating earthquakes and tsunamis.
