Serious and widespread destruction occurred in Luhuo County.
A major earthquake occurred during the rule of the Qing dynasty in Shandong Province on July 25, 1668. It had an estimated magnitude of 8.5, making it the largest historical earthquake in East China, and one of the largest to occur on land. An estimated 43,000 to 50,000 people were killed, and its effects were widely felt. Its epicenter may have been located between Ju and Tancheng counties, northeast of the prefecture-level city of Linyi in southern Shandong.
The 1995 Menglian earthquake or 1995 Myanmar–China earthquake occurred on 12 July at 05:46:43 local time in the Myanmar–China border region. The earthquake had an epicenter on the Myanmar side of the border, located in the mountainous region of Shan State. It registered 7.3 on the Chinese surface wave magnitude scale (Ms ) and 6.8 on the moment magnitude scale (Mw ). With a maximum Mercalli intensity assigned at VIII, it killed 11 people and left another 136 injured. Over 100,000 homes in both countries were destroyed and 42,000 seriously damaged. Some damage to structures were also reported in Chiang Mai and Chiang Rai, Thailand. The low death toll from this earthquake was attributed to an early warning issued prior to it happening. Precursor events including foreshocks and some seismic anomalies led to an evacuation of the area before the mainshock struck. It is thought to be one of the few successfully predicted earthquakes in history.
The 2021 Luxian earthquake was a damaging seismic event occurring in the early hours of September 16 at 04:33 China Standard Time.

Three people were killed and 146 injured when the earthquake struck Lu County, Luzhou, Sichuan Province. At least 36,800 buildings were affected, 7,800 of them seriously damaged or completely destroyed, causing about a quarter of a billion dollars worth of damage.
An earthquake occurred on June 19, 1718, in Tongwei County, Gansu Province, Qing dynasty, present-day China. The estimated surface wave magnitude (Ms ) 7.5 earthquake was designated a maximum Modified Mercalli intensity of X (Extreme), causing tremendous damage and killing 73,000 people.
The 1850 Xichang earthquake rocked Sichuan Province of Qing China on September 12. The earthquake which caused major damage in Xichang county had an estimated moment magnitude of 7.6–7.9 Mw and a surface wave magnitude of 7.5–7.7 Ms . An estimated 20,650 people died.
