According to the Municipal Seismological Bureau, at 1:39 on June 15, 2023, a magnitude 3.1 earthquake occurred in Qingpu District, Shanghai, with a focal depth of 8 kilometers. The earthquake is about 40 kilometers away from the people's Square. Judging from the regional structural characteristics and the level of historical seismic activity, it will not have a serious impact on the city. So far, no casualties and damage to buildings have been reported. The Municipal Seismological Bureau will continue to do a good job in follow-up monitoring.
The earthquake has attracted widespread attention on various social media platforms. Some netizens said that when an earthquake occurred, they could clearly feel the beds and wardrobes shaking, and the desk lamp on the bedside table also shook, but there were no serious consequences. In a video posted by netizens, it is evident that there is a sound similar to muffled thunder during an earthquake, and the camera also shakes.
Mr. Guan, who lives in the Qingpu New City area, told us that 31.07 degrees north latitude and 121.09 degrees east longitude are located in Xinsheng Village, Zhujiajiao Town, Qingpu District. Tao Genhua, the secretary of the village party branch, told reporters that he was sleeping when the earthquake occurred. Shortly after being woken up, he received a call from the relevant department in the town, asking him to notify the village committee to rush to the village committee immediately. "I immediately notified other village officials and, after understanding the situation, went to the four areas of Nanzhi, Panjing, Wangjiadai, and Xuxiang in the village for investigation, mainly to determine whether there were any injuries to personnel or damage to houses. The investigation work ended around 6:30 am and no casualties or damage to buildings were found. There were small cracks on the walls outside some homesteads, but it was uncertain whether it was caused by the earthquake. The villagers' emotions were generally stable."
Will earthquakes have an impact on the buildings in the Zhujiajiao Ancient Town scenic area? Gu Jiandi, the director of the Zhujiajiao Town Scenic Area Office, told reporters that he was also very concerned about this situation after the earthquake occurred, and carried out a situation investigation as soon as possible. Currently, no buildings in the ancient town scenic area have been affected by the earthquake.
Will there be aftershocks after this earthquake? According to the introduction of the Municipal Seismological Bureau, based on the structural characteristics near the epicenter, historical seismic activity, and sequence type characteristics, comprehensive analysis suggests that there is little possibility of a larger earthquake occurring in the area in the near future, and no aftershocks have been detected so far.
The reporter learned that earthquakes can be divided into shallow source earthquakes, medium source earthquakes, and deep source earthquakes according to the depth of the source. Shallow earthquakes mostly occur within a range of 30 kilometers or more below the surface, while deep earthquakes can reach depths of up to 650 kilometers. Among them, shallow earthquakes have a high frequency of occurrence, accounting for more than 70% of the total number of earthquakes, and the released seismic energy accounts for 85% of the total released energy. They are the main creators of earthquake disasters and have the greatest impact on humanity.
According to historical records, there have been no destructive earthquakes in Shanghai. History shows that there have been no earthquakes with a magnitude of 5.0 or higher within a 50 kilometer radius of the epicenter. The largest and most recent earthquake with a magnitude of 3.0 or above was the Qingpu 3.0 magnitude earthquake in Shanghai on February 17, 1991, located 4 kilometers from the epicenter and causing no casualties.
