How to prevent geological disasters?, News 1+1 | Extreme Flood Season | Geological Disasters | News
As soon as July entered this year, rain warnings were constantly issued in various regions. News 1+1 invites Chen Hongqi, Senior Engineer of the Geological Disaster Technology Guidance Center of the Ministry of Natural Resources, to jointly pay attention to: How to prevent geological disasters during flood season?
"Seven down and eight up" is coming soon. What should be done first to prevent geological disasters?
Chen Hongqi, Senior Engineer of the Geological Disaster Technology Guidance Center of the Ministry of Natural Resources: From the pattern of previous years, "seven down and eight up" has a large amount of rainfall and frequent disasters, which is also the heaviest time for geological disaster prevention and control tasks. The Ministry of Natural Resources or local natural resource departments have already done some targeted work, such as strengthening on duty duty, encrypted monitoring and early warning, including experts, technology, and forces stationed on the front line to support. The most important thing now is to closely monitor the rain and water conditions. Sometimes both rainfall and rainfall areas are localized, such as continuous rainfall in one place, with a superimposed effect. Therefore, the prediction of short-term rainfall, including downstream attention to upstream water conditions, strengthening meteorological risk warning of geological disasters, especially in densely populated areas, is very important and urgent. In addition, having a warning is not enough. It is necessary to check the defense plan, including emergency plans, division of labor, and whether measures are ready. Of course, we also need to strengthen the investigation of risks and hidden dangers.
Special attention should be paid to geological disaster prevention due to sudden changes in drought and flood, as well as extreme weather changes
Chen Hongqi, Senior Engineer of the Geological Disaster Technology Guidance Center of the Ministry of Natural Resources: From the perspective of the factors affecting geological disasters, the most concerning is extreme weather changes, whether it is extreme drought or flood, or abnormal rainfall, which are all things we need to pay attention to. Due to the rapid changes in drought and flood, rock formations are more sensitive to water, so special attention should be paid especially in the early stages of drought and when extreme rainfall may occur in the later stages.
Facing geological disasters: early warning, emergency avoidance, and transfer are the most important
Chen Hongqi, Senior Engineer of the Geological Disaster Technology Guidance Center of the Ministry of Natural Resources: In terms of extreme weather warning and forecasting, the most important thing is to timely release and share short-term temporary rain and water information, and inform the threatened population and those living in areas prone to geological disasters of the warning information. According to the risk level, where the risk is high, urgent risk avoidance and transfer measures need to be taken. We have had a mentality of taking chances in the past, such as ignoring or ignoring warning information, not evacuating in a timely manner, or not following the control of the danger zone and returning after evacuating, which has led to many lessons of casualties. Therefore, we need to pay special attention to warning information and make early warning responses.
What help does the investigation of data on geological hazards in over 280000 locations nationwide bring to the prevention of geological disasters?
Chen Hongqi, Senior Engineer of the Geological Hazards Technical Guidance Center of the Ministry of Natural Resources: The role is very significant. The probability of geological disasters occurring in any place is high, and data is the foundation. Previous data actually reflected the basic laws of history, and we need to master these basic laws. At the same time, I suggest not being limited to the understanding of these experiences. Especially, I suggest that everyone analyze changes in the environment, pay more attention to monitoring data, especially short-term warning information, and make judgments based on the new situation. Especially when it comes to "seven down and eight up", I think it is also a time of high density for tourists, outsiders, and people seeking summer shelter in mountainous areas. Therefore, we use this data information to make more warnings, announcements, and public announcements about risks and hidden dangers, so that more people can know. I think this is very important.
