Our news (reporter Zhang xuanhuayu) according to the measurement of China seismic network, at 13:54 Beijing time on November 17, 2021, a magnitude 5.0 earthquake occurred in the sea area of Dafeng District, Yancheng City, Jiangsu Province (33.50 degrees north latitude and 121.19 degrees east longitude), with a focal depth of 17 kilometers. The reporter learned from Jiangsu Seismological Bureau that the possibility of aftershocks of the same level is small, and the public need not panic.

“Before two o’clock in the afternoon, when I was sleeping in the dormitory, I suddenly felt the door shaking and felt someone knocking at the door for about half a minute.” Mr. Wang, a citizen of Yancheng, told reporters that his roommate got out of bed to open the door and found that no one continued to sleep. “I thought I didn’t wake up at that time. When I looked at my circle of friends, I knew that there was an earthquake just now.”

Yang Yun, deputy director and senior engineer of Jiangsu seismological station, introduced that after the Dafeng sea area earthquake, Jiangsu Seismological Bureau also immediately started the earthquake emergency level III response, established the emergency headquarters of Jiangsu Seismological Bureau, and sent the first batch of earthquake field teams to Dafeng District, Yancheng City to carry out disaster investigation, mobile monitoring, scientific investigation and other work. According to the preliminary investigation and Statistics: most areas of our province were affected by the earthquake, among which Yancheng, Nantong and other areas were more affected by the earthquake; Some coastal areas of neighboring provinces (cities) such as Shanghai, Shandong and Zhejiang are interested. At present, no casualties have been reported. The mood of the people near the earthquake area was generally stable and the social production and life order was normal. After preliminary verification by counties (cities and districts), no casualties and property losses caused by the earthquake have been found in coastal towns, parks, enterprises, offshore wind power facilities and fishing boats.

The epicenter of the earthquake was in the sea. Why did Shanghai, Nanjing and other cities feel the earthquake? Yang Yun explained that the earthquake source in Dafeng sea area is shallow, so the impact range is large. Especially in Jiangsu, the whole overburden is relatively thick, and the overburden will amplify the seismic energy. In addition, the time of the earthquake is the working time of the public, and the body feeling is stronger.

Wang Jun, a senior engineer of Jiangsu seismological station, reminded that in case of an earthquake, first of all, don’t panic. Quickly find a supporting object that can bear weight indoors, a small bay with load-bearing walls and other shock absorption space, squat down and protect the head and back neck with hands or cushions. If you encounter an earthquake outdoors, you should choose an open area nearby. Don’t run around, let alone return indoors.
