Tectonic Summary This earthquake occurred within the strike-slip Sagaing fault system in south-central Myanmar (formerly known as Burma) or on a related fault system. The Sagaing fault system is a large north-south trending feature whose surficial expression stretches nearly 1000 km from Mandalay in the north to Pegu in the south. Movement along the Sagaing fault system results from the northward motion of the Indian plate with respect to southeast Asia. The moment-tensor solution for the earthquake is consistent with the right-lateral sense of slip on the Sagaing fault that has been inferred from geological evidence.
