At 23:59 on December 18, a 6.2-magnitude earthquake occurred in Jishishan County, Linxia Hui Autonomous Prefecture, Gansu Province, which aroused everyone's attention to the distribution of mainland seismic zones. As we all know, the places on the mainland that are most prone to earthquakes are Sichuan, Hebei, Xinjiang and other places. Among them, the Tangshan earthquake and the Wenchuan earthquake are the most influential earthquakes. Due to the vast geography of the mainland, there are areas prone to earthquakes, and there are areas that are not prone to earthquakes.
What are the most earthquake-prone areas in China?
Zhejiang Province
Zhejiang Province is located on the southeast coast of the mainland, belonging to the southern wing of the Yangtze River Delta, and is located at the eastern edge of the East China Seismic Zone. Compared with some areas with frequent earthquakes, the seismic activity in Zhejiang is relatively stable, and there are few obvious earthquakes. This is mainly due to the fact that Zhejiang Province is located on the edge of the East China Seismic Zone, which is relatively weak in seismic activity relative to the central area of this seismic zone.
Since the beginning of the 21st century, there have been three earthquakes in Zhejiang, and the seismic magnitude is not high. On September 23, 2014, a 4.0-magnitude earthquake struck Wencheng County, Wenzhou City, Zhejiang Province, on October 25, 2014, a 4.0-magnitude earthquake struck Wencheng County, Wenzhou City, Zhejiang Province, and on April 12, 2017, a 4.2-magnitude earthquake struck Lin'an City, Hangzhou City, Zhejiang Province.
Hunan Province
Hunan Province is located in southern China, in the middle reaches of the Yangtze River, and is one of the regions with relatively stable seismic activity. The seismic activity in Hunan Province is mainly affected by the tectonic background of South China, and is relatively stable on the whole.
According to the monitoring data of the Hunan Provincial Earthquake Bureau, since 1500, Hunan has experienced a total of moderate and strong destructive earthquakes of magnitude 224 or more. Among them, the 6.8 magnitude earthquake in Changde in 1631 became one of the two largest earthquakes ever recorded in the inland region of South China.
Hubei Province
Hubei Province is located within the continental continental plate, unlike some earthquake-prone areas located on the edge of the plate. Therefore, Hubei Province is not one of the major seismic zones on the mainland. Since 143 BC, there have been 33 devastating earthquakes in Hubei Province.
On January 17, 2023, two earthquakes of magnitude 3 or higher occurred in Nanzhang County, Xiangyang City, Hubei Province within 4 minutes.
Jiangxi Province
Jiangxi is located in the South China coastal seismic statistical area, surrounded by mountains on three sides and rivers on one side. This geographical environment makes Jiangxi relatively less directly affected by tectonic activities, such as seismic and volcanic belts are usually concentrated at the edge of the crustal plate, while Jiangxi is located inside the plate.
The most recent earthquake in Jiangxi Province occurred on July 2, 2018 in Fuliang County, Jingdezhen City, Jiangxi Province, with a magnitude of 3.6 and an epicenter depth of 5 kilometers.
Although the seismic activity in the above provinces is relatively weak, the existence of seismic risks cannot be ruled out. The earth's geological activity is a complex process, and earthquakes are a way for energy to be released from the earth's interior. Even in seemingly stable areas, the earth's crust can still change, leading to earthquakes.
In conclusion, regardless of the level of earthquake risk in the region, it is important to take appropriate earthquake prevention measures, including building earthquake-resistant buildings, strengthening infrastructure, and raising public awareness of earthquakes. Local governments and communities should develop and implement earthquake response plans to mitigate the damage that earthquakes can cause.
