A reliable road network is a vital local asset, connecting communities and unlocking economic growth. Every year landslides cause serious damage and, in some cases, the full disruption of many networks, which can last from few days to even months. The identification monitoring with conventional methods on an extended complex be rather difficult process, as it requires significant amount time resources. Chania regional unit island Crete Greece typical example, connects, over long distances,...
Advances in synthetic aperture radar (SAR) interferometry have enabled the seamless monitoring of Earth’s crust deformation. The dense archive Sentinel-1 Copernicus mission provides unprecedented spatial and temporal coverage; however, time-series analysis such big data volumes requires high computational efficiency. We present a parallelized-PSI (P-PSI), novel, parallelized, end-to-end processing chain for fully automated assessment line-of-sight ground velocities through persistent...
This research focuses on the investigation of hydrogeological hazards in open pit coal mines. The study area is Amyntaio sub-basin area, located West Macedonia prefecture, Greece. A major part SE this occupied by mine. In recent decades, basin’s aquifer has been overexploited both dewatering wells mine and irrigation wells, triggering extensive land subsidence an that extends 3 km around Additionally, one biggest mining landslides worldwide occurred South-West slopes 10 June 2017. current...
Abstract. The potential of repeat-pass space borne SAR (Synthetic Aperture Radar) interferometry has been exploited to investigate spatial patterns land subsidence in the Anthemountas basin, northern part Greece. PSI (Persistent Scatterer Interferometry) approach, based on processing long series acquisitions, applied forty-two images acquired 1995–2001 by ERS1/2 satellites. Interferometric results have analysed at a basin scale as support for motion mapping and local characterisation ground...
Over the preceding decades, climate change has affected precipitation, most common factor triggering landslides. The aim of this study is to highlight impact by examining precipitation trends in Chania regional unit, Greece, with help time series provided 21 local meteorological stations covering a period from 1955 2020. analysis also focuses on extreme events February 2019, where monthly cumulated amount reached 1225 mm, one highest ever recorded Greece. Moreover, an inventory past and...
Landslides are one of the most severe geohazards globally, causing extreme financial and social losses. While InSAR time-series analyses provide valuable insights into landslide detection, mapping, monitoring, AI is also implemented in a variety geohazards, including landslides. In present study, machine learning (ML) susceptibility map proposed that integrates geotectonic units Greece incorporates various sources data. Satellite data from Persistent Scatterer Interferometry analysis,...
Land subsidence phenomena caused by the overexploitation of aquifers require holistic knowledge geological, tectonic, hydrogeological and especially geotechnical conditions affected sites in order to be mitigated. The current paper focuses on study taking place at Amyntaio sub-basin, northern Greece, hosting homonymous open pit coal mine, operating there last two decades. mining as well rising agriculture activities have led a significant drawdown ground water level triggering extensive...
The United Arab Emirates (UAE) is located in an arid desert climate with very limited water resources and scarce rainfall. Along the fast development of country, demand for agriculture, industrial, domestic purposes increased led to diminishing groundwater resources. In this study, we explore land surface deformations due overexploitation agricultural area Remah by analyzing Sentinel-1 data between 2015 2019 novel Parallelized-Persistent Scatterer Interferometry (P-PSI) technique. detected...
Land subsidence in coastal and delta cities often results infrastructure residential building damages, while also increasing the area’s flooding vulnerability. The of Messolonghi Aitolikon are typical examples, as they built on top old stream deposits near coast. In last several years, gradual sites, combined with impact climate change, resulted multiple floods. rush seawater over lowlands has been reported. Persistent scatterer interferometry (PSI) is a remote-sensing technique that can...
The exploitation of remote sensing techniques has substantially improved pre- and post- disaster landslide management over the last decade. A variety susceptibility methods exists, with capabilities limitations related to scale spatial accuracy issues, as well data availability. Interferometric Synthetic Aperture Radar (InSAR) have significantly contributed detection, monitoring, mapping phenomena. present study aims point out contribution InSAR in detection evaluate two different models by...
Abstract In March 2021 three strong earthquakes with magnitudes (Mw) of 6.3, 6.0, and 5.2 occurred in Thessaly plain, Greece, on 3, 4, 12 March, respectively. The modeling all the sources, by inversion Interferometric Synthetic Aperture Radar Global Positioning System data, indicates a northeast–southwest-trending extensional stress field indications for northeast-dipping sources. unmapped fault source first mainshock (Mw 6.3) is located approximately 6 km to southwest known Larissa (LF)....
