Abstract

The 2016-2017 seismic sequence in the Central Apennines (Italy) necessitated a comprehensive revision of the Hydrogeological Asset Plans landslide database to support post-seismic reconstruction. To address this critical need for updated risk assessment, this study aims to develop and validate an automated workflow for classifying and prioritizing landslide-prone areas, providing government institutions with a systematic approach to landslide risk assessment. Our innovative methodology integrates multi-sensor Persistent Scatterers (PS) interferometric data, advanced clustering techniques, and socio-economic factors to establish a standardized procedure for monitoring hazardous areas and optimizing resource allocation. The multi-sensor analysis reveals that approximately 6% of landslides are undetectable by interferometric technique, 45% show stability with no PS-detected deformation, and 19% are accurately mapped with deformation confined within their boundaries. Notably, 30% of analyzed landslides exhibit displacement beyond their mapped perimeters, indicating potential expansion or underestimation of their extent. This comprehensive classification enables authorities to identify and prioritize critical areas requiring immediate intervention based on hazard levels and socio-economic impact. The study concludes that this multi-sensor approach significantly enhances the efficiency of field inspections and territorial planning by providing a data-driven framework for intervention prioritization, ensuring that reconstruction efforts are both scientifically grounded and economically justified.
基于PS-InSAR聚类分析和社会经济影响的区域滑坡自动优先排序
2016-2017年意大利亚平宁中部的地震序列需要对水文地质资产计划滑坡数据库进行全面修订,以支持震后重建。为了满足更新风险评估的迫切需求,本研究旨在开发和验证一种自动工作流程,用于对滑坡易发地区进行分类和优先排序,为政府机构提供一种系统的滑坡风险评估方法。我们的创新方法集成了多传感器持续散射体(PS)干涉测量数据、先进的聚类技术和社会经济因素,建立了监测危险区域和优化资源分配的标准化程序。多传感器分析表明,大约6%的滑坡无法通过干涉测量技术检测到,45%的滑坡表现出稳定性,没有ps检测到变形,19%的滑坡被精确地绘制出来,变形被限制在其边界内。值得注意的是,所分析的滑坡中有30%的位移超出了其绘制的周长,表明其范围可能扩大或低估。这种全面的分类使当局能够根据危害程度和社会经济影响确定需要立即干预的关键领域并确定优先次序。该研究的结论是,这种多传感器方法通过为干预优先级提供数据驱动的框架,显著提高了现场检查和领土规划的效率,确保重建工作既有科学依据,又有经济合理性。

期刊介绍: The journal ''Remote Sensing Applications: Society and Environment'' (RSASE) focuses on remote sensing studies that address specific topics with an emphasis on environmental and societal issues - regional / local studies with global significance. Subjects are encouraged to have an interdisciplinary approach and include, but are not limited by: " -Global and climate change studies addressing the impact of increasing concentrations of greenhouse gases, CO2 emission, carbon balance and carbon mitigation, energy system on social and environmental systems -Ecological and environmental issues including biodiversity, ecosystem dynamics, land degradation, atmospheric and water pollution, urban footprint, ecosystem management and natural hazards (e.g. earthquakes, typhoons, floods, landslides) -Natural resource studies including land-use in general, biomass estimation, forests, agricultural land, plantation, soils, coral reefs, wetland and water resources -Agriculture, food production systems and food security outcomes -Socio-economic issues including urban systems, urban growth, public health, epidemics, land-use transition and land use conflicts -Oceanography and coastal zone studies, including sea level rise projections, coastlines changes and the ocean-land interface -Regional challenges for remote sensing application techniques, monitoring and analysis, such as cloud screening and atmospheric correction for tropical regions -Interdisciplinary studies combining remote sensing, household survey data, field measurements and models to address environmental, societal and sustainability issues -Quantitative and qualitative analysis that documents the impact of using remote sensing studies in social, political, environmental or economic systems
