An earthquake occurred in Douli Mountain, Lianyuan, Hunan.

The seismic activity in China is mainly distributed in 23 seismic zones in five regions. These five regions are:

① Taiwan Province Province and its adjacent waters;

(2) Southwest China, mainly Tibet, western Sichuan and central and western Yunnan;

(3) Northwest China, mainly distributed in Hexi Corridor of Gansu, Qinghai and Ningxia and the foothills of Tianshan Mountain;

④ North China, mainly located on both sides of Taihang Mountain, Wei Fen Valley, Yinshan-Yanshan area, Luzhong and Bohai Bay;

⑤ Southeast coastal areas such as Guangdong and Fujian. Taiwan Province province in China is located in the Pacific Rim seismic belt, Tibet, Xinjiang, Yunnan, Sichuan and Qinghai provinces are located in the Himalayan-Mediterranean seismic belt, and other provinces are located in related seismic belts.

The distribution of China's seismic zones is an important basis for formulating key earthquake monitoring and defense areas in China.
