China News Service, August 30. According to the WeChat public account of the Ministry of Natural Resources, on August 30, the Ministry of Natural Resources held a meeting to reschedule and redeploy the rescue and rescue work for the debris flow disaster in Jilong, Tibet. The meeting listened to the opinions and suggestions of academicians and experts, and made requirements for forward rescue and rescue risk management work.
Since August 28, the Ministry of Natural Resources has launched a comprehensive investigation of risks and hazards in disaster areas, mobilizing professional technical forces in the natural resources system, carrying drones, rangefinders and other survey equipment, and dividing them into four working groups. Focusing on ice avalanche source areas, barrier lakes, along channels and around the basin, the Ministry of Natural Resources has carried out emergency mapping and risk hazard investigations on disaster-affected areas by region, and strengthened geological disaster inspections and inspections in key areas such as emergency rescue channels, surrounding villages and resettlement sites.
Up to now, experts from the front and rear have combined remote sensing interpretation and on-site investigation to interpret more than 60 geological disaster hazard points in the disaster-affected area, and initially determined 8 high-risk locations. It is recommended to use drone aerial surveys combined with manual inspections for monitoring during the search and rescue period. In addition, the natural resources system was organized to coordinate professional and technical personnel, grassroots cadres, group inspection and prevention personnel, etc. A total of more than 1,070 inspection personnel were dispatched to expand the scope of inspection to more than 900 geological disaster hazard points.
The meeting requested that risk monitoring in the debris flow source area should be further strengthened, and manual observation posts, integrated lightning monitoring equipment, and microseismic monitoring equipment should be deployed on the opposite bank of the Cuojian River Estuary. The combination of the three can achieve rapid early warning; risk research, judgment, and monitoring of potential risks of collapses and landslides caused by scraping of trenches along the path of debris flow should be continued. At the same time, it is recommended that the forward command headquarters set up emergency shelters for search and rescue teams and delineate emergency escape routes to ensure the safe and orderly conduct of rescue and rescue work.
