1988 Lancang–Gengma earthquakes
Major earthquakes near the Myanmar–China border region / From Wikipedia, the free encyclopedia
The 1988 Lancang–Gengma earthquakes (simplified Chinese: 澜沧江-耿马地震; traditional Chinese: 瀾滄江-耿馬地震; pinyin: Láncāngjiāng-gěng mǎ dìzhèn), also known as the 11.6 earthquakes by the Chinese media were a pair of devastating seismic events that struck Lancang and Gengma counties, Yunnan, near the border with Shan State, Burma.[1] The earthquake measured moment magnitude (Mw ) 7.0 and was followed 13 minutes later by a 6.9 Mw shock.[2] These earthquakes were assigned a maximum China seismic intensity of IX and X, respectively. Between 748 and 939 people were killed; more than 7,700 were injured. Both earthquakes resulted in US$270 million (in 1988 dollars) in damage and economic losses. Moderately large aftershocks continued to rock the region, causing additional casualties and damage.
