基于无人机影像的皮山地震极灾区烈度评估

Assessment of seismic intensity in the Pishan earthquake extreme disaster area based on UAV images

  • 摘要: 2015年7月3日新疆维吾尔自治区皮山县(37.6°N,78.2°E)发生MS6.5地震,震源深度10 km。本文采用无人机遥感影像,结合新疆地震现场调查的真实资料,提取了灾区震害信息,采用地震烈度遥感定量评估方法完成了极灾区地震烈度遥感评估,并且完善了新疆多结构类型建筑物地震烈度遥感评估方法。结果表明:皮山地震极灾区地震烈度遥感评估结果与地震现场调查结果一致,与中国地震局公布的皮山地震烈度图中该区域的地震烈度一致,遥感评估结果较为准确。该方法的完善可为今后新疆地震烈度遥感评估工作服务,为今后新疆无人机遥感技术的深入应用提供基础。

     

    Abstract: On July 3, 2015, An earthquake (MS6.5) occurred near Pishan county (37.6°N, 78.2°E), Hotan Prefecture Xinjiang Uygur Autonomous Region, China, with a focal depth of 10 km. Using UAV remote sensing images and field investigation information, seismic damage information in the disaster area is extracted. Seismic intensity remote sensing quantitative assessment method is used to evaluate earthquake intensity in the disaster area. The results show that the remote sensing assessment method for seismic intensity of multi-structure types of buildings in Xinjiang has been improved by combining the real data of earthquake field investigation. The results of remote sensing assessment of seismic intensity in Pishan earthquake-stricken area are consistent with the results of field investigation, and the seismic intensity in this area is consistent with that in Pishan earthquake intensity map published by China Earthquake Administration. The improvement of this method can serve for the future remote sensing assessment of seismic intensity, and provide a basis for the application of the UAV remote sensing technology in Xinjiang in the future.
