Wavelet analysis of land subsidence time-series: Madrid Tertiary aquifer case study [PDF]

open access: yesProceedings of the International Association of Hydrological Sciences, 2020
Interpretation of land subsidence time-series to understand the evolution of the phenomenon and the existing relationships between triggers and measured displacements is a great challenge.

Comprehensive identification of potential and old landslides based on optical remote sensing and InSAR technologies: A case study in northwestern Yunnan Province

open access: yesZhongguo dizhi zaihai yu fangzhi xuebao, 2022
Potential geological disasters frequently occur in northwestern Yunnan. Landslide is the main type of geohazard. The identification of landslide in this area is an effective disaster prevention and mitigation measure.

Application of the Interferometry Synthetic Aperture Radar (InSAR) in monitoring and evaluating landslides (case study: Ahar-Varzeghan region) [PDF]

open access: yesنشریه جغرافیا و برنامه‌ریزی, 2021
Introduction Risk management and landslide assessment begin with a comprehensive identification and monitoring of their movements and mapping them, which can be used as a basis for achieving knowledge about their spatial and temporal distribution.

Ground deformation and fissure activity in Datong basin, China 2007–2010 revealed by multi-track InSAR

open access: yesGeomatics, Natural Hazards & Risk, 2019
The Datong basin is one of the complex geologic environments in China. Several faults are distributed in the basin, and a number of hidden faults have been discovered within the basin. Ground fissures (GFs) and land subsidence occur in this region.

Monitoring of Masjed-Soleiman embankment dam’s deformation using a combination of Interferometric Synthetic Aperture Radar (InSAR) and finite element modeling

open access: yesGeodesy and Cartography, 2017
The fresh water shortage is one the most important challenges in many countries like Iran. So there have been incentives to manipulate and manage water resources by constructing dams. Clay core embankments are one of the most popular dam structures.

Generative Modeling of InSAR Interferograms [PDF]

open access: yesEarth and Space Science, 2019
AbstractInterferometric synthetic aperture radar (InSAR) has become an essential technique to detect surface variations due to volcanoes, earthquakes, landslides, glaciers, and aquifers. However, Earth's ionosphere, atmosphere, vegetation, surface runoff, etc., introduce noise that requires post‐processing to separate its components.

2014年新疆于田MS7.3地震的发震构造及余震特征

open access: yesDizhen xuebao, 2021
利用2014年10月至2019年9月期间欧空局Sentinel-1卫星采集的合成孔径雷达数据分析了2014年2月12日新疆于田MS7.3地震的震后形变场。结果表明,此次地震造成了南硝尔库勒断裂上明显的震后形变,首次从地震形变场的角度验证了此次地震的发震构造为NE向的左旋走滑断裂,而非部分研究所认为的近NS向断裂。由合成孔径雷达干涉测量得到的多年平均速率图显示主震的西侧仅出现了少量震后余滑且仍为强闭锁区,这意味着2008年和2014年于田两次MS7.3地震之间的区域仍存在发生强震的风险 ...

Ellipsoid‐Based Interval‐Type Uncertainty Model Updating Based on Riemannian Manifold and Gaussian Process Model

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Modern engineering systems require advanced uncertainty‐aware model updating methods that address parameter correlations beyond conventional interval analysis. This paper proposes a novel framework integrating Riemannian manifold theory with Gaussian Process Regression (GPR) for systems governed by Symmetric Positive‐Definite (SPD) matrix ...
