Recently, under the guidance of Chen Yi, deputy director of the Seismological Bureau of Sanmenxia, the reporter came to the hillside of the South 200 meter village of Chuan Kou Township, Lingbao City. Here, reporters saw a group of geological experts wearing helmets in a busy and orderly manner. At this time near noon, under the scorching sun, a UAV is circling in the sky.
Seeing reporters looking up at the unmanned drones, Chen explained: "in January 24th this year, the National Seismological Bureau conference proposed the goal of China to enter the world's Seismological power by 2030. In order to achieve this grand blueprint, the state launched the national seismological technology innovation project, that is' transparent crust '. The four major projects are "earthquake resilience" and "smart service". We seize this rare opportunity and carry out the detection of active faults in Sanmenxia rapidly. Through the detection of the buried active faults in Sanmenxia, the experts obtain the accurate location and activity of active faults and provide basic data and technical support for the implementation of the "transparent crust". Now we are in the position of active fault detection.
Dong Li, deputy director of the first monitoring center of China Earthquake Administration, who is working at the site, said: "the purpose of the use of the UAV is to scan the section of the active fault in the Sanmenxia area, and to get a complete geological profile image by filming the cross-sectional images of different positions, after the later splicing and processing, so that the active fault is constructed. There is a clearer and more precise quantitative cognition. In the next step, we also need to make a comprehensive analysis of the collected information and accurately locate the known active faults and hidden active faults in the Sanmenxia work area, so as to provide a favorable guarantee for the safe and smooth development of the local development and construction. "
At this point, in the one section of the mountain, the project leader, the national first class earthquake safety engineer Wang Lei, the project technical director Tara, the senior engineer Zhou Haitao, Shen Xiaoqi, the geo radar group doctor Yu Daxin, the Engineer Qiu Jun and so on are dancing the pickaxe in the mountain hillside to find the live fault.
"The methods of active fault detection include satellite remote sensing image interpretation, aerial photo interpretation, field geological survey and other means. There are many forms of active faults, some are exposed on the earth's surface, some are hidden underground. Active faults exposed on the surface can be interpreted by remote sensing satellite images. However, remote sensing satellite images are often difficult to identify in some microscopic scale or in specific areas. In recent years, the rapid development of UAV low altitude photography technology has effectively solved these problems. The unmanned aerial vehicle (UAV) loading high definition camera can shoot high resolution photos from the height of hundreds of meters, and can accurately identify the linear structure and the change of topography and topography caused by the fault activity. The active faults in Sanmenxia are mainly the temperature pond fault and the cotton concave fracture. Through the unmanned aerial vehicle (UAV) for high definition image shooting where the manpower is unable to reach, and then the photographs are processed, the evidence for the existence of the active faults can be detected accurately, so as to accurately locate the position of the active faults in Sanmenxia, for scientific planning and in the city Earthquake prevention and disaster reduction service.
