- Abstract:
- The Ludian seismic area situated in the high-mountain gorge areas of northeast Yunnan. Due to the complex topography landforms and the poor development of quaternary system,the conventional investigation condition of active landforms are poor. The rapid development of UAV aerial survey technology in recent years has demonstrated outstanding advantages in the collection of geomorphological data. In this paper,the UAV aerial survey technology is applied to the research of active tectonics in the Ludian seismic area. Combined with the field investigation and trench site selection,we discussed the work flow with UAV aerial survey technology of remote sensing data collection in active tectonics in seismic area. Based on the data acquisition and image interpretation of the UAV aerial survey,two groups of densely distributed surface ruptures were obtained along the Baogunao-Xiaohe fault at Xiaoyakou in Guangmin village. Along the Zhaotong-Ludian fault,we found the dextral displacement of the gully and the ridge is about 70m and disclosed faults through trench work along the fault trough in Xinpengzi village based on the remote sensing image interpretation. It demonstrates better application effect of the UAV aerial survey technology on active tectonics research in mountainous area.
