Earthquake in Yunnan, China
From Wikipedia, the free encyclopedia
The 1917 Sichuan earthquake occurred on 31 July, in Yunnan Province, Republic of China, with a moment magnitude of 7.0,[1] killing at least 1,800 people.[2]
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.[3][4]

The earthquake had an epicenter located 42 km (26 mi) west from the town of Xunchang which is a part of the Yunnan Province. It had a maximum Modified Mercalli intensity of IX (Violent).[1] The earthquake was felt in Ludian, Hechuan, Hanyuan, Rong, Yibin, Dafang, Wutongqiao, Bijie, Weining and Huize.[2]
