The combined effects of global warming and human activities have intensified land subsidence (LS), limiting sustainable development economy in delta regions. Despite the potential Interferometric Synthetic Aperture Radar (InSAR) for monitoring LS, its application across vast regions may be hindered by complex data processing, high computational demands, need standardized results. To overcome these challenges, we adopted multi-temporal InSAR (MT-InSAR) technique, integrating a frame parallel...
Abstract We derive the ALOS‐2 coseismic interferograms, pixel‐offsets and Sentinel‐2 sub‐pixel offsets of 2023 M w 7.8 7.7 Kahramanmaras, Turkey earthquake sequence. Offset maps show that sequence ruptured ∼300 km along East Anatolian Fault (EAF) ∼180 secondary Cardak Dogansehir faults. infer slip distribution interseismic fault motion by inverting co‐ inter‐seismic observations. Inversion results (∼8.0 m) strike‐slip rate (∼4.6 mm/yr) on main rupture event are basically consistent with ∼8.4...
On February 6, 2023 (local time), two earthquakes (Mw7.8 and Mw7.7) struck central southern Turkey, causing extensive damage to several cities claiming a toll of 40,000 lives. In this study, we propose method for seismic building assessment analysis by combining SAR amplitude phase coherence change detection.

In February 2023, Mw 7.8 and 7.7 earthquakes struck southeastern Turkey. Generating a coseismic 3D deformation field that can directly reflect the characteristics of surface is important for revealing movement mode seismogenic fault analyzing focal mechanism. Optical image sub-pixel correlation (SPC) only captures in horizontal direction, SAR pixel offset tracking (POT) obtains range not sensitive to north–south signals. Thus, neither them capture complete alone. Combining may be able allow...
Multi-temporal Interferometric Synthetic Aperture Radar (MT-InSAR) has been widely used for ground motion identification and monitoring over large-scale areas, due to its large spatial coverage high accuracy. However, automatically locating assessing the state of from massive (InSAR) measurements is not easy.

However, existing studies using detect...
In recent years, increasing available synthetic aperture radar (SAR) satellite data and gradually developing interferometric SAR (InSAR) technology have provided the possibility for wide-scale ground-deformation monitoring using InSAR. Traditionally, InSAR are processed by existing time-series (TS–InSAR) technology, which has inefficient calculation redundant results. this study, we propose a wide-area variable-scale deformation detection strategy (hereafter referred to as WAVS–InSAR...
Many coastal cities reclaim land from the sea to meet rapidly growing demand for caused by population growth and economic development. Settlement in reclaimed may delay construction even damage infrastructures, so accurately predicting settlement over areas is important. However, limited observation ambiguous final estimation affect accurate prediction traditional methods. This study proposes a new strategy solve these problems using Multitemporal Interferometric Synthetic Aperture Radar...
Abstract This study monitors the land subsidence of whole Pearl River Delta (PRD) (area: ~ 40,000 km 2 ) in China using ALOS1/PALSAR data (2006–2011) through SBAS-InSAR method.
