摘要
选取土耳其卡赫拉曼马拉什省努尔达吉镇城区和周边乡村地区作为研究区,通过获取地震前后的高空间分辨率遥感影像数据,提取房屋建筑震害信息,识别房屋建筑震害等级,利用震害指数计算区域内地震烈度等级,综合分析得到建筑物震害特征与主要成因,对地震灾情快速评估、应急救援和恢复重建具有重要参考.
Abstract
The urban area and surrounding rural areas of Nurdagi Town,Kahramanmarash Province,Turkey were selected as the research area.By obtaining the high spatial resolution remote sensing image data before and after the Turkey earthquake,the seismic damage information of buildings was extracted,and the seismic damage level of buildings was identified.The seismic damage index was used to calculate the seismic intensity grade in the region,and the seismic damage characteristics and main causes of buildings were comprehensively analyzed.It has important reference for rapid assessment,emergency rescue and reconstruction of earthquake disaster.
