Yanjin County is located in the northeast of Yunnan Province, China, bordering Sichuan Province to the north and east. It is under the administration of the prefecture-level city of Zhaotong.

The 1925 Dali earthquake occurred at 14:42 UTC on 16 March. It had an estimated magnitude of 7.0 on the surface-wave magnitude scale and a maximum perceived intensity of at least IX (Violent) on the Mercalli intensity scale. It had an epicenter in the province of Yunnan in southern China and killed an estimated 5,000 people.

An earthquake occurred on 1 June 1786 in and around Kangding, in what is now China's Sichuan province. It had an estimated magnitude of about 7.75 and a maximum perceived intensity of X (Extreme) on the Mercalli intensity scale. The initial quake killed 435 people. After an aftershock ten days later, a further 100,000 died when a landslide dam collapsed across the Dadu river.

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. 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; Chinese sources put these at 7.4 and 7.3 on the Ms7 scale. 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.

The 1988 Lancang–Gengma earthquakes, 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. The earthquake measured moment magnitude (Mw ) 7.0 and was followed 13 minutes later by a 6.9 Mw  shock. 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 damage and economic losses. Moderately large aftershocks continued to rock the region, causing additional casualties and damage.

The 2003 Dayao earthquake occurred on July 21, at 23:16:33 CST. The epicenter of the moment magnitude 5.9 earthquake was in Dayao County in the mountainous area of central Yunnan, China. At least 19 people were killed, 644 were injured, and 8,406 families became homeless. The quake also caused $75 million USD in damage.

The 1913 Eshan earthquake struck China's Yunnan Province on 21 December with a moment magnitude of 6.8 and maximum Mercalli intensity of IX (Violent). The shock devastated Eshan County; at least 942 people died and thousands of homes were destroyed. The earthquake ruptured along a section of the strike-slip Qujiang Fault.

The 1733 Dongchuan earthquake affected Yunnan in China on August 2. The earthquake, which had an estimated surface-wave magnitude of 7.75, damaged homes across the province. There were dozens of fatalities and more deaths occurred in mines. The earthquake was the result of faulting along the Xiaojiang Fault Zone.
