Abstract: Based on sampling damaged building rate of destroyed region identified by using Airborne SAR image with 3m or 6m resolution, this paper presents the method of quick determing epicentral areas with the reference of damaged building rates and its intensity response models of 3 types of earthquake. Its results are very helpful for the quick response to the earthquake emergency decision-making.
Key words: Earthquake disaster assessment, Epicentral area, Airborne SAR
摘要: 利用3m 或6m 分辨率的机载SAR震害影像,获取高烈度区样本单元的房屋毁坏率,并以此为特征参量,根据3 种不同类型地震建立的房屋毁坏率与烈度响应模型,确定相应烈度房屋毁坏率的阈值,最终快速确定极震区并圈定其范围,这对地震抢险救灾具有重要意义。
