In recent years, the Ningbo Plain has experienced significant surface subsidence due to urbanization and industrialization, combined with area’s unique geological hydrological conditions. To study its causes in Plain, this analyzed 166 scenes of Sentinel-1A SAR images between January 2018 June 2023. The time series interferometric synthetic aperture radar (TS-InSAR) technique was used acquire information area. were analyzed. results show that: (1) annual deformation rate ranges from −44...
Abstract Anthropogenic land subsidence is an example of changes to the natural environment due human activities and one key factors in causing degradation at a range scales. Previous studies assessing Valley Mexico either focused on regional scale or short (noncontinuous) temporal scale. In this study, long‐term (~15 years) mapped City (Mexico) using two interferometric synthetic aperture radar (InSAR) methods, namely, GEOS (Geoscience Earth Observing Systems Group)‐Advance Time‐series...
On 17 June 2020, a large ancient landslide over the Aniangzhai (ANZ) slope, Danba County, Sichuan Province, China, was reactivated by series of multiple phenomena, including debris flow triggered heavy rainfall and flooding. In this study, Synthetic Aperture Radar (SAR) images acquired Sentinel-1A/B satellite optical captured PlanetScope satellites were jointly used to analyze explore deformation characteristics Spatial-Temporal evolution ANZ before after multi-hazard chain. Several areas...
A large earthquake with a magnitude of MW 7.3 struck the border Iran and Iraq at province Kermanshah, Iran. In our study, coseismic deformation source model 12 November 2017 Kermanshah Earthquake are investigated using ALOS-2 ScanSAR Sentinel-1A/B TOPSAR Differential Interferometric Synthetic Aperture Radar (DInSAR) techniques. Geodetic inversion has been performed to constrain parameters invert slip distribution on fault plane. The optimised from joint shows blind reverse relatively...
Small earthquakes following a large event in the same area are typically aftershocks, which usually less destructive than mainshocks. These aftershocks considered mainshocks if they larger previous mainshock. In this study, records of (M > 2.5) Kermanshah Earthquake 7.3) Iran were collected from first second to end September 2018. Different machine learning (ML) algorithms, including naive Bayes, k-nearest neighbors, support vector machine, and random forests used conjunction with slip...
The ancient Aniangzhai (ANZ) landslide in Danba County, Sichuan Province of southwest China was reactivated after a series complex hazard events that occurred June 2020. Since then, and until 2021, emergency engineering work carried out to prevent the further failure landslide. This study investigates potential joint use time Interferometric Synthetic Aperture Radar (InSAR) optical pixel offset tracking (POT) assess deformation characteristic spatial-temporal evolution ANZ during...
The Lianjiang Plain, renowned for its position as ‘China’s textile hub’ and characterized by high population density, has experienced considerable subsidence due to excessive groundwater extraction in recent years. Although some studies have investigated short-term this plain, research on long-term rebound remain understudied. In paper, the characteristics of surface deformation Lijiang Plain during two periods (2015–2017 2018–2021) been using time-series interferometric synthetic aperture...
The ancient Aniangzhai (ANZ) landslide in Danba County, Sichuan Province of southwest China was reactivated after a series complex hazard events that occurred June 2020. Since then, emergency engineering work carried out to prevent further failure the landslide. This study investigates multi-temporal optical images (3 m spatial resolution) acquired from PlanetScope satellite with pixel offset tracking (POT) technique assess deformation characteristic and spatial-temporal evolution ANZ during...
In this paper, the 2017 Maoxian landslide in Sichuan province, China was investigated by using multi-temporal SAR and optical datasets. The pre- post-failure scars of were depicted K-means classification Normalized Difference Vegetation Index (NDVI) maps. Two stacks ascending descending Sentinel-1A/B C-band images applied to explore pre-failure characteristics event. Advanced time-series InSAR analysis processed detect movements event, with identifying spatial-temporal pattern evolution...
In this paper, the 2020 Aniangzhai Landslide in Danba County Sichuan province, China was investigated by using multi-temporal SAR and optical datasets. The pre- post- failure scars of landslide debris flow were depicted high-resolution images from Planetscope satellites. descending Sentinel-1A/B C-band applied to explore deformation characterization event. Advanced time-series InSAR analysis processed detect sliding motion, with identifying spatial-temporal pattern evolution area landslide....
Most deep learning networks for Lidar semantic segmentation have been devoted to small-scale indoor data and only few of them focused on large-scale outdoor data. To bridge this gap, research explores the influences changing features accuracy segmentation. Surface normal information random downsampling layers are two considered. Eight scenarios designed test them. Point clouds acquired from Kapiti Coast, New Zealand in 2021 with five labeled classes used training, validation, testing stages....
In this paper, ground deformation and source model of the 12 November 2017 Kermanshah Earthquake (border region between Iran Iraq) are investigated by using ALOS-2 ScanSAR Sentinel-lAiB TOPSAR co-seismic Differential Interferometric Synthetic Aperture Radar (DInSAR) measurements. Geodetic inversion has been performed to constrain parameters invert slip distribution on fault plane. Stress changes neighboring active faults around area estimated based deformation. The best-fit shows a reverse...
