At 12:52 on September 5, an earthquake of magnitude 6.8 occurred in Luding County, Ganzi Prefecture, Sichuan Province. In the event of an earthquake during the novel coronavirus pneumonia epidemic, how to quickly choose the correct hedging method?
On September 5, Wang Tun, professor of Sichuan University, director of the Sichuan Key Laboratory of Earthquake Early Warning and Multi-hazard Early Warning Application Information Technology, and director of the Chengdu High-tech Disaster Reduction Research Institute, explained this.
“When two emergencies are concurrent, we need to consider the issue of the priority of risk avoidance based on the degree of danger and the degree of urgency based on the warning time. If the degree of danger is similar, the event with higher urgency needs to be dealt with first; If there is a large difference in severity, the event with a higher degree of danger should be dealt with first.” Wang Tun said that in the past 30 years of disasters, although the “black swan” and “grey rhino” catastrophes are small in probability, in-depth research is still needed. Early warning mechanism, response plan, drill plan, resolution plan, supporting laws and regulations, etc. After the magnitude 5.1 earthquake in Qingbaijiang District, Chengdu, Sichuan, the Sichuan Provincial Department of Emergency Management formulated the "Key Work Plan for Preparedness for Major and Extraordinary Earthquakes During the Epidemic Period", and researching and formulating countermeasures for early warning information for double or multiple emergencies is an emergency management work. Work content that requires further consideration.
He said that at present, the new crown pneumonia epidemic has sounded the alarm for the whole society to establish an early warning mechanism. We should also continue to establish a response mechanism that is appropriately beyond the early warning response level, rely on technical means to support early warning information, and through the early warning mechanism may help the public "rush Come out" some precious time for escape and safety.

How to properly avoid danger during a sudden strong earthquake during the epidemic? He said that during the epidemic, people need to prepare an epidemic prevention-earthquake emergency kit, which includes water, compressed biscuits, thermal blankets, flashlights, whistles, folding knives, toilet paper and medical kits. In addition, you can prepare more masks and an appropriate amount of alcohol disinfectant in the emergency kit, but be careful to keep away from fire sources. When an earthquake occurs, if the people are isolating at home, they can roughly judge the distance and strength of the earthquake, and then choose different shock absorption methods.
He said that at present, most of the buildings in my country have reached the seismic fortification standard of "not damaged in small earthquakes, repairable in moderate earthquakes, and not collapsed in large earthquakes". Therefore, if an earthquake with a smaller magnitude occurs, you should try your best to protect yourself from being injured by falling objects; if you encounter an earthquake with a larger magnitude nearby, you should bring an epidemic prevention-earthquake emergency kit and choose an indoor safe area to avoid nearby. At the same time, if people can go outdoors, they need to wear masks, run to open areas as soon as possible, and maintain a safe distance from the crowd; if people avoid earthquakes indoors, they do not need to consider epidemic prevention, and only need to take normal indoor safety precautions The method is enough, such as protecting the head, hiding in the survival triangle area, away from glass and hanging objects, etc.; if the early warning earthquake intensity is not highly destructive, the priority of epidemic prevention is high, and epidemic prevention measures need to be taken before the earthquake is avoided.
