Land subsidence in the coastal zone of the Neo Faliro, Moschato, and Kallithea municipalities, along the Faliro bay, has been recorded since the mid 1960’s. This phenomenon has caused damage to buildings, pavements, and roads. Aiming to identify the main causes of the observed ground deformations, data referring to the geological, geotechnical, and hydrogeological settings of the study area has been evaluated. Subsidence has been quantified by the use of space-born Synthetic Aperture Radar interferometry (InSAR) techniques. SVD (Singular Value Decomposition) and IPTA (Interferometric Point Target Analysis) techniques have been applied for the production of deformation maps, referring to the time period between 2002 and 2010. Furthermore, aiming to extend the study of the phenomenon further to the past, Persistent Scatterer Interferometry (PSI) data for the time period from 1992 to 2001 were also evaluated. Finally, the results of the InSAR analysis have been crosschecked with measurements acquired by a vertical geodetic control network as well as by ground truth data, referring to damage inventory of the site. The current research presents an interesting case study of an urban site affected for a long-lasting period by the activities of a neighboring industrial zone. The development of an extensive depression cone, mainly due to the overexploitation of the aquifers for industrial use, is the main cause of the land subsidence phenomenon, without excluding a component of motion due to the natural compaction of the compressible soil in the area of interest. The complexity of the geological, hydrogeological, and geotechnical conditions and the interaction of the numerous land use activities make this study far more interesting.

影响城市场地的含水层过度开发引发的地面沉降：以法利罗湾（希腊）雅典沿岸地区为例

自 1960 年代中期以来，沿 Faliro 湾的 Neo Faliro、Moschato 和 Kallithea 市沿海地区的地面沉降已有记录。这种现象对建筑物、人行道和道路造成了破坏。为了确定观测到的地面变形的主要原因，对涉及研究区地质、岩土和水文地质环境的数据进行了评估。沉降已通过使用星载合成孔径雷达干涉测量 (InSAR) 技术进行量化。SVD（奇异值分解）和 IPTA（干涉点目标分析）技术已用于制作变形图，参考 2002 年至 2010 年之间的时间段。此外，旨在将对该现象的研究进一步扩展到过去，还评估了 1992 年至 2001 年期间的持续散射干涉测量 (PSI) 数据。最后，将 InSAR 分析的结果与垂直大地控制网络获得的测量结果以及地面实况数据（参考站点的损坏清单）进行了交叉检查。当前的研究提供了一个有趣的案例研究，该案例研究长期受到邻近工业区活动影响的城市场地。大面积凹陷锥体的发展，主要是由于工业用含水层的过度开发，是地面沉降现象的主要原因，不排除由于感兴趣区域可压缩土壤的自然压实引起的运动分量. 地质、水文地质、
