A massive earthquake of magnitude M_w 7.3 shook Kermanshah Province in Western Iran along the Iraqi border on November 12, 2017. The epicenter of the earthquake was approximately 10 km southwest of Ezgeleh Town in Kermanshah Province. Field observations almost 4 months after the disaster indicated that the earthquake had caused tremendous damage to most structures in both urban and rural areas, and left an enormous amount of disaster waste. To investigate the status of the damage and disposal of the disaster waste, remote sensing was conducted using an unmanned aerial vehicle (drone). Through the capture of low-altitude images by drone and the generation of 3D models, the quantity of debris accumulated in a waste disposal facility near Sarpol Zahab was estimated at approximately 480,000 m³. A compositional analysis of the disaster waste was performed using an imaging technique. This revealed that the disaster waste was largely composed of concrete (39.6%), hollow brick (35.4%), and gypsum (21.2%) in the urban area, whereas soil was the dominant component (77.4%) in the rural area. The damage caused to most buildings was essentially due to their non-standard construction. The management of debris from the damaged buildings was a critical issue for the authorities, and the lack of preparedness was a serious drawback that consumed an enormous amount of time, budget, and workforce. A practical post-disaster preparedness plan would help the decision-makers and the public to manage the otherwise overwhelming nature of the post-disaster conditions in a more reasonable manner.

从2017年11月的Ezgeleh-Sarpol Zahab地震中学到的教训：灾祸的状况和废物处置

级的大地震中号_W¯¯ 7.3震撼克尔曼沙阿省西部沿伊朗与伊拉克边境11月12日，2017年地震的震中大约在克尔曼沙阿省Ezgeleh镇10公里西南。灾难发生后近四个月的现场观察表明，地震对城乡大多数建筑物造成了巨大破坏，并造成了大量的灾难性浪费。为了调查灾害废物的破坏和处置状况，使用了无人驾驶飞机（无人机）进行了遥感。通过无人机捕获低空图像并生成3D模型，估计在Sarpol Zahab附近的废物处理设施中积累的碎屑量约为480,000 m³。使用成像技术对灾难废物进行了成分分析。这表明，城市地区的灾害废弃物主要由混凝土（39.6％），空心砖（35.4％）和石膏（21.2％）组成，而土壤是农村地区的主要成分（77.4％）。对大多数建筑物造成的损害主要是由于它们的非标准构造。损坏建筑物的碎片管理对于当局来说是一个关键问题，而缺乏准备是一个严重的缺点，浪费了大量的时间，预算和劳动力。切实可行的灾后准备计划将帮助决策者和公众以更合理的方式管理灾后状况的压倒一切。
