作者进行了一项全面的研究，以确定 2011 年东北海啸灾难的影响，并了解重建东北地区以建立海啸抵御能力社区的经验教训。首先，作者通过现场测量和卫星遥感确定了海啸淹没区的范围。应用光学卫星图像的特定索引来提取用地面实况数据（现场调查数据）校准的海啸内陆渗透。其次，通过现场测量、航空照片和视频检查与空间信息科学的综合研究，以海啸流速和水动力的形式了解海啸内陆渗透的水动力方面，初步结果以海啸脆弱性曲线的形式对2011年海啸的结构脆弱性以及对土地利用管理和土地利用的启示有了新的认识。 重建有复原力的沿海社区的搬迁规划。
The authors conducted a comprehensive study to identify the impact of the 2011 Tohoku tsunami disaster and to understand the lessons towards the reconstruction of Tohoku to build tsunami-resilient community. First, the authors identified the extent of tsunami inundation zone by field measurement and satellite remote sensing. A specific index for optical satellite images was applied for the extraction of tsunami inland penetration calibrated with the ground truth data (field survey data). Second, an integrated investigation of field measurement and aerial photo and video inspections with spatial information sciences was performed to understand the hydrodynamic aspect of tsunami inland penetration with a form of tsunami flow velocity and hydrodynamic force, and the preliminary results lead to new understandings of structural vulnerability against the 2011 tsunami with a form of tsunami fragility curve and an implication for land use management and relocation planning to reconstruct resilient coastal communities.
