The epicenter was located in the area around Lazha (拉鲊), Dalongtan (大龙潭) Township, Renhe District, Panzhihua and Yuzha (鱼鲊) Township, Huili County. Lazha then belonged to Yongren County, Yunnan and now within Sichuan. Yuzha then belonged to Huili County, Sichuan as it still does. The earthquake had a magnitude of s y 6.8.Significant Earthquake Database https://www.ngdc.noaa.gov/nndc/struts/form?t=101650&s=1&d=1 https://web.archive.org/web/20060929000601/http://www.ngdc.noaa.gov/nndc/struts/form?t=101650&s=1&d=1 dead September 29, 2006 National Geophysical Data Center / World Data Service (NGDC/WDS) 1972 National Geophysical Data Center, NOAA 10.7289/V5TD9V7K 728 people were reported dead and 1547 injured in the earthquake.http://www.xinhuanet.com/zhibo/20080903/zhibo.htm 新华网直播 Xinhua News Agency 22 May 2022 https://web.archive.org/web/20080923034542/http://www.xinhuanet.com/zhibo/20080903/zhibo.htm 23 September 2008 dead More than 15000 rooms collapsed. Eight people died and seven houses collapsed in the Xigeda (昔格达) Village.http://www.panzhihua.gov.cn/zjpzh/pzhsz/depzrhjyzy/861.shtml 第二章 地震 panzhihua.gov.cn 2013-04-23 https://web.archive.org/web/20160304114923/http://www.panzhihua.gov.cn/zjpzh/pzhsz/depzrhjyzy/861.shtml 2016-03-04 dead Cracks ranging from 10 to 70 cm in width and 100 to 1,500 m in length occurred on hillsides and ridges. Landslides were observed along both banks of the Jinsha River. Many villages on both banks of the Jinsha River were destroyed. Rivers and springs dried up, and many new springs appeared. Changes of water level in wells and ditches were reported. Many villages on both banks of the Jinsha River were destroyed. Along the Jinsha River and its surrounding gullies, large quantities of rocks broke, fell, and dammed up the gullies. In the Jinsha River, waves surged 1 m high. The maximum intensity reached MM IX. The shaking could be felt as far as about 400 km away. The Xigeda-Yuanmou fault (昔格达—元谋断裂带), about 270 km long, is the seismogenic structure of this earthquake."昔格达断裂晚第四纪活动特征及强震复发周期" by 卢海峰 and 姬志杰 From the distribution of the isoseismals of this earthquake, it was suggested that there is a three-layered structure. There is a rupture layer, and there are two complete rock layers located in both sides of the rupture layer. The rupture layer is the place where the stress was concentrated and released and has the role of reflecting the seismic wave propagation."中国强震发生带地震构造的几点思考" by 李坪, 黄广思, and 杨美娥 See also List of earthquakes in 1955 List of earthquakes in China References External links 889946 Yuzha earthquake, 1955 Category:Earthquakes in Sichuan Category:Earthquakes in Yunnan Category:History of Panzhihua Category:20th century in Sichuan
