A magnitude 5.0 earthquake occurred in the waters of Jiangsu at 13:00 on November 17, 2021. The earthquake was felt in surrounding cities, especially in places like Yancheng, Jiangsu, where the earthquake was felt very strongly. Earthquakes are often accompanied by aftershocks, and some aftershocks are also very dangerous. You are not aware of an earthquake when it comes, and only some small animals have premonitions, such as fragrant dogs that keep barking. But we humans cannot predict earthquakes. When we face earthquakes, we have good protective measures. Now many primary schools have used earthquake prevention drills to enable students to deal with earthquakes calmly and achieve maximum safety. . The earthquake that occurred in the Jiangsu sea area this time is not particularly harmful. It can be said that it is not harmful, but it may cause some damage to the structure of the house, which may cause cracks in the long walls of the house, leading to some dangerous existences. . Although there is no harm to the human body, we still need to pay attention to protection. Earthquakes take many lives every year, so we have to pay attention to safety. Although we cannot predict earthquakes and cannot effectively predict earthquakes, we can show united determination in the face of earthquakes. I believe not many people noticed this earthquake. It is estimated that some people were eating in restaurants, some were driving on their way to work, and some were lying in bed sleeping. Of course, there is no shortage of people who discover earthquakes. They are paying attention to everything around them all the time. They only know that an earthquake has occurred when they see objects shaking around them. When they knew that the earthquake had occurred, they were probably in a state of confusion. They didn't know what to do or what to do. Instead, they stood there and watched silently. The earthquake went away. I hope we can all survive earthquakes safely in the future. I wish everyone in the disaster area good health and no disasters. At the same time, we also hope that we will have no natural disasters in any period in the future.
