Has anyone heard of the 8.5-magnitude earthquake in Tancheng, Linyi, Shandong three hundred years ago?

On the evening of July 25, 1668 (Xu time on June 17, the seventh year of Kangxi reign in the Qing Dynasty), a devastating earthquake occurred in Tancheng, Shandong Province, affecting more than 10 provinces and 410 counties in East and North China. , and even about 500 county chronicles, local chronicles, inscriptions, poems, etc. on the Korean Peninsula have detailed records of this earthquake. Among them, there are records of damage in more than 150 counties. It is a major earthquake with the most detailed and rich historical records in history.

The area most severely affected by this earthquake was the junction of today's Tancheng, Linyi, and Linshu. According to the "Kangxi Tancheng County Chronicle", "On June 17, the seventh year of Kangxi, there was an earthquake at Xushi. There was a sound coming from the northwest. For a while, the buildings and trees all leaned forward and backward, with their tops touching the ground two or three times in a row. Each one of them collapsed, and the towers collapsed. The fortresses, official residences, private houses, villages, temples and temples all collapsed to the ground... then the ground cracked, springs gushed out, spraying two or three feet high, water flowed all over the ground, all the ditches were full, and when they moved, they turned into nothing, and people stood on the ground. It is like walking on a round stone, tossing and swaying, unable to stand. It collapses when it moves, and it is fixed when it moves. About hundreds of thousands of houses in the city collapsed. The cracks in the ground are either too wide to cross or too deep to look at. The depressions are all layered like classes, and there are silt and fine sand on both sides of the cracks. The depth, width, and shape of the depressions are difficult to describe. It is truly a strange disaster in ancient times." In addition, most of Shandong, Jiangsu, and northern Anhui suffered varying degrees of damage.

This earthquake is the only 8.5-magnitude earthquake in eastern my country and one of the three 8.5-magnitude earthquakes in China (the other two are the 8.5-magnitude Haiyuan earthquake in Ningxia on December 16, 1920 and the 8.5-magnitude earthquake in Haiyuan, Ningxia on November 18, 1950 The 8.5-magnitude earthquake in Chayu, Tibet, Japan) killed about 50,000 people.
