The Karapinar basin, located in the Central Anatolian part of Turkey, is subjected to land subsidence and sinkhole activity due extensive groundwater withdrawal that began early 2000s. In this study, we use Interferometric Synthetic Aperture Radar (InSAR), Global Navigation Satellite System (GNSS), level data monitor better understand relations between extraction, subsidence, formation basin. main observations used study are InSAR-derived velocity maps calculated from both Sentinel-1...
30 Ekim 2020 tarihinde Sisam adası kuzeyinde Mw:6.9 büyüklüğünde bir deprem meydana gelmiştir. Bu İzmir şehir merkezinde ve bazı ilçelerinde can mal kayıplarına yol açmıştır.

Abstract. One of the potential dangers that might arise as a result bringing excessive amounts groundwater to surface Earth is land subsidence. Such deformations – these velocities may vary from few millimetres metres per year do greatest damage infrastructure facilities and buildings in residential units. Agricultural lands, which irrigation performed, densely populated cities are more likely suffer Konya Closed Basin (KCB), where rapid withdrawal has been observed during last 30–40 years,...
The escalating occurrence of landslides has drawn increasing attention from the scientific community, primarily driven by a combination natural phenomena such as unpredictable seismic events, intensified precipitation, and rapid snowmelt attributable to climate fluctuations, compounded inadequacies in engineering practices during site selection. Within scope this investigation, contemporary geodetic techniques using GNSS were employed monitor structural surface deformations around hospital...
We investigated rupture geometry, size, and slip distribution of October 30, 2020, Samos (Sisam)-Kuşadası earthquake combining seismographs, GPS measurements, SAR analysis. Right after the earthquake, we measured 13 additional campaign-based sites to intensify available network consisting 10 continuous stations. combined all seismographs have best possible accuracy for mainshock aftershock hypocenter locations. compiled seismic profiles integrated them using high-resolution bathymetry map...
The aim of this study is to determine and monitor the areas affected by land subsidence caused decrease groundwater, using geodetic methods in Konya Closed Basin, Turkey.The GPS InSAR techniques which complement each other perfectly will be used deduce spatial deformations subsidence.The activity area Küçükköy situated at Basin (KCB) Central Anatolia Region Turkey has been studied Stanford Method for Persistent Scatterers (StaMPS) technique.Significant movements ranging from mm cm per year...

A destructive Mw = 6.2 earthquake struck NW Croatia on 29 December 2020, ranking among the most hazardous events in country last century. This study assesses impact of permanent geodetic stations Croatian national positioning system. Using a novel approach, we combined station data with satellite radar for first time geodynamic across Croatia. The analysis involved collecting daily solutions from 11 nearby network as well multi-temporal images before and after earthquake. results reveal...
The main purpose of this paper is to investigate climate change impact that have been occurred on Salt Lake
 located in the central Anatolia one area has faced extinction. In order monitor current
 status Lake, Landsat satellite images obtained between year 2000 and 2014 (for the
 months February, May, August November). Satellite processed by using ArcGIS and
 ERDAS softwares water surface determined. time series areas has
 analyzed with auto-correlation method...
PPP (Precise Point Positioning) is a relatively new GNSS (Global Navigation Satellite System) method that enables position determinations using single receiver. Being able to survey with receiver makes this approach more attractive and affordable than other positioning techniques. Since used, drawback of technique propagation errors such as orbit clock uncertainties, atmospheric disturbances etc. Due these errors, precision point may reach up decimeter levels. Fortunately, some error sources...
In this study, the accuracy of Precise Point Positioning (PPP) method was investigated. For purpose, a micro-geodetic network containing 5 stations established and 8-hour GNSS Global Navigation Satellite System (GNSS) sessions for three consecutive days were performed. At same time, baselines between in measured by Electronic Distance Meter (EDM) height differences are geometric leveling method. The results obtained from classical terrestrial measurements, which considered to be highly...
Bu çalışmada, HNK (Hassas Nokta Konumlama) yönteminin kabuk deformasyonu belirleme çalışmalarında kullanılabilirliği, rölatif GNSS (Global Navigation Satellite System) analizleri eşliğinde araştırılmıştır. amaçla, Kuzey Anadolu Fay (KAF) hattının kuzeyinde yer alan GIRS, SINP ve ZONG istasyonları ile söz konusu fay güney kesiminde konumlanan RHIY, ANKR BILE TUSAGA-Aktif (Türkiye Ulusal Sabit Ağı-Aktif) istasyonlarının 2011-2018 (8 yıl) yılları arasındaki periyodik verileri elde edilerek...
Mühendislik yapılarındaki olası deformasyonların izlenmesi, yapısal bütünlük, güvenlik ve maddi kaynakların korunumu için önemli etkileri olabilecek kritik bir konudur. Bu zamanında, doğru etkili jeodezik yöntemle izlenmesi can mal kayıplarının önüne geçilmesinde hayati önem taşımaktadır. kapsamda daimi yansıtıcı interferometre (PSI) tekniği geniş alansal izleme kabiliyeti, yüksek çözünürlükte santimetre altı doğruluk sunması, kısa geçiş süresi ile mühendislik izlenmesinde güçlü teknik...
