It had an estimated magnitude of 7.0 on the surface-wave magnitude scale and a maximum perceived intensity of at least IX (Violent) on the Mercalli intensity scale.Chen X.L. Zhou Q. Ran H.

Tectonic setting Yunnan lies in a tectonically complex zone affected by the broad zone of deformation associated with the ongoing collision between the Indian plate and the Eurasian plate. A rhomb-shaped fault-bounded block, known as the Sichuan-Yunnan Block, is recognised that is bounded by the active left-lateral strike-slip faults of the Xianshuihe fault system and the currently right lateral Red River Fault and Jinshajiang Fault.Allen C.R.
