Why has there been no earthquake in Dunhuang City, Gansu Province?

Because Dunhuang City is not located in the plate boundary zone, the crustal movement is not strong.

Reason: Dunhuang City, Gansu Province is under the jurisdiction of Jiuquan City and is located in the westernmost part of Gansu Province. The longitude and latitude are 92°13′~95°30′ east longitude and 39°40′~41°40′ north latitude. Dunhuang City borders Aksai County in Xinjiang to the west, Hainan Mongolian Autonomous Prefecture of Qinghai Province to the south, Subei Mongolian Autonomous County to the north and is close to Ejina Banner of the Alxa League of the Inner Mongolia Autonomous Region. It is located in the four provinces of Gansu, Xinjiang, Qinghai and Inner Mongolia. Area junction.

Generally speaking, the areas where earthquakes are prone to occur are at the junctions of plates. The collision and extrusion between plates will cause violent movement of the earth's crust and cause earthquakes. Dunhuang City obviously does not have such conditions. China has two major seismic zones, one is the Mediterranean-Himalayan seismic zone and the other is the Pacific Rim seismic zone. Among them, the Mediterranean-Himalayan seismic zone is the junction of the Eurasian plate and the Indo-Australian plate (Indian Ocean plate), mainly in the southern and eastern edges of the Qinghai-Tibet Plateau in China, that is, in the southern Tibet Autonomous Region, western Yunnan Province and southwestern Sichuan Province; ring The Pacific Seismic Belt is the junction of the Eurasian and Pacific plates. It is mainly located in the northeastern region of China and the eastern coastal provinces. It is an arc from Heilongjiang to Guangxi. Dunhuang City is located in the interior of China, far away from the Mediterranean-Himalayan seismic zone and the Pacific Rim seismic zone. It is less affected by plate collisions and compression, and the earth's crust is relatively stable, so it is not prone to earthquakes.
