1976 earthquake sequence in the Yunnan-Myanmar border region
The 1976 Longling earthquake in Yunnan Province, People's Republic of China, was a doublet earthquake, with two main shocks striking just east of Longling at 12:23:20 and 14:00:22 UTC (20:23 and 22:00 local time). The magnitudes were estimated at 6.7 and 6.6, respectively, on the Mw(GCMT) scale, and 6.9 and 7.0 on the Ms scale;[5] Chinese sources put these at 7.4 and 7.3 on the Ms7 scale.[6] The region is noted for the quantity and intensity of its earthquakes, and the complexity of its tectonics, which are closely related to the collision between the Indian and Eurasian tectonic plates.[7]
No one died in the Longling county town[8] Loss in the 9 counties in Baoshan, Lincang and Dehong were 98 deaths, 451 severe injuries and 1991 light injuries. 420,000 buildings collapsed in an area of 1883 square kilometers.[9]
