It had a maximum felt intensity of X (Extreme) on the Modified Mercalli intensity scale, and caused thousands of deaths.National Geophysical Data Center / World Data Service (NGDC/WDS): NCEI/WDS Global Significant Earthquake Database.

The plateau is spreading laterally eastwards, to southeastwards, partly accommodated by a series of major strike-slip faults. The Sichuan–Yunnan block is bounded to the northeast and east by the left lateral Xianshuihe fault system and to the southwest by the right lateral Red River Fault. Xichang is sited at the southern end of the Anninge segment of the Xianshuihe fault system, close to its junction with the Zemuhe segment.Wang H. Ran Y. Chen L.

This is supported by paleoseismological investigations. A trench dug across the northern end of the Anninge segment found evidence of a rupture consistent with the 1536 event but a trench across the northern end of the Zemuhe segment lacked any such evidence.Feng J.

In Xichang all buildings were destroyed, including government offices, prisons, storehouses and houses (both military and civilian). The city walls, gates, battlements and watchtowers collapsed. Many people were crushed to death, including several senior officials.Tong P. 2023 The Social Impact of Earthquake Disasters in Sichuan in the Ming Dynasty Environment, Resource and Ecology Journal 7 5 51–57 10.23977/erej.2023.070506 free Further north in Mianning, every house was destroyed and the city walls completely collapsed and thousands were killed. Parts of the city walls also collapsed in Yuexi, Qionglai, Ya'an, Dayi and Meishan.
