GPS ve Ps-Insar Yöntemleri Kullanılarak Koyulhisar (Sivas) Heyelanlarının İzlenmesi: İlk Sonuçlar
PS-InSAR teknigi son yillarda genellikle, deprem nedeni ile olusan deformasyonlarin, volkanik alanlardaki yer degisimlerinin ve hidrolojik, jeolojik, madencilik ya da sehir alanlarinda olusan cokmelerin belirlenmesinde kullanilmaktadir. Ancak heyelanlarin hareketlerinin belirlenmesinde belki de goreli olarak yeni bir yontem olmasi nedeniyle cok sik ...

Abstract On 27 July and 25 October 2022, an Mw 7.0 earthquake and an Mw 6.4 earthquake struck Abra, northwest of Luzon, Philippines, respectively, with a time interval of less than 3 months and a distance of about 16 km. In this research, interferometric synthetic aperture radar (InSAR) was utilized to retrieve the co‐seismic surface deformation field ...

A First Approach for Displacement Analysis in Lisbon Downtown Using PS-InSAR
AbstractLisbon Downtown presents unique geomorphologic properties which makes it an area prone to terrain instability. Serious accidents have occurred there, namely, during the 1755 earthquake and a flooding event at the extension of a subway line, demanding a frequent monitorization for safety reasons and expense minimization. In this study, Permanent

Abstract From 2019 to 2024, gravity surveys were conducted at the Three Sisters volcanic cluster (TSVC), measuring 246 gravity sites using a spring relative gravimeter. We calculated the residual Bouguer anomaly and identified three main zones with negative anomalies, ranging from −4 to −8 mGal, located southwest and west of South Sister, within an ...

InSAR Ground Deformation and Pumping Energy Consumption Reveal Urban Water Security
Abstract Water resource assessments are critical for ensuring water security (WS), particularly in rapidly urbanizing regions with increasing water demand and limited water monitoring capabilities. Earth observations and indirect indicators of surface and groundwater changes are valuable tools for developing such assessments.

Abstract Magma and pressure transport between Kīlauea's summit reservoirs and along its East Rift Zone (ERZ) are dynamic even in the absence of surface eruptions. However, these processes do not always produce surface manifestations and may sometimes elude detection by current geological and geodetic monitoring.

Abstract Observations of fluid‐driven swarm seismicity expanding with the same diffusive space‐time behavior as analytical solutions for aseismic slip have been interpreted as evidence that stress changes from aseismic slip trigger seismic slip. In some cases, aseismic slip is confirmed from crustal deformation measurements or sheared wellbore casing ...

The morphology of initial PS/LLDPE films changes from lamellar to fibrillar structure after mechanical recycling by extrusion, followed by an improvement in mechanical properties. ABSTRACT In the latest decade, intensive research work was dedicated to multi‐micro/nanolayer systems as an alternative to classical multilayer systems, aiming to reduce the ...

Abstract A limitation in our understanding of the geodynamics of orogenies is the difficulty in resolving the spatial variations in long‐term processes such as exhumation of the crust. Although geodesy can record ground motions to millimeter‐scale precision at high spatial and temporal resolutions, these observations only cover a small fraction of the ...
