The 1679 Sanhe-Pinggu earthquake (Chinese: 三河—平谷地震; pinyin: Sānhé—Pínggǔ dìzhèn) was a major quake that struck the Zhili (Greater Beijing) region in Qing China on the morning of September 2, 1679.

[1] It is the largest recorded surface rupture event to have occurred in the North China Plain.

The epicenter was located approximately 50 km (31 mi) east of the Imperial Palace in Beijing.

The earthquake struck sometime between 9 am and 11 am on Saturday, September 2, 1679, and had its epicenter in Sanhe, modern day Hebei Province.

A 2007 study by Risk Management Solutions found that an earthquake similar in size to the 1679 Sanhe-Pinggu event could have devastating effects and result in the deaths of between 35,000 and 75,000 people.
