Özet:

 This study aims to statistically analyze the spatial effects of the Kahramanmaras-centered earthquakes that occurred on February 6, 2023, using internet-based GNSS data evaluation services. The observations of 14 fixed stations of the TUSAGA-Active network were analyzed with CSRS-PPP, MagicGNSS, and Trimble RTX software. In addition, the data of the EKZ1 station, which was most affected by the earthquake, dated 06022023 at different time intervals, were also evaluated using these software. The effects of the earthquake on the stations X, Y, and Z coordinate axes were statistically analyzed with both ANOVA and Kruskal-Wallis tests. The analyses include statistical analysis of the statistical differences of coordinate values obtained from GNSS services according to different days before, during, and after the earthquake and other time intervals of the earthquake day. It was determined that the coordinate differences before and after the earthquake were statistically significant, especially in the Y coordinate axis. In contrast, the changes in the Z coordinate axis were less than in the other axes. Hourly analyses for the EKZ1 station revealed that the spatial changes were statistically significant.

 Bu çalışma, 6 Şubat 2023 tarihinde meydana gelen Kahramanmaraş merkezli depremlerin konumsal etkilerini, internet tabanlı GNSS veri değerlendirme servisleriyle istatistiksel olarak analiz etmeyi amaçlamaktadır. TUSAGA-Aktif ağına ait 14 sabit istasyonun gözlemleri, CSRS-PPP, MagicGNSS ve Trimble RTX yazılımlarıyla incelenmiştir. Ayrıca, depremden en çok etkilenen EKZ1 istasyonunun 06022023 tarihli farklı saat aralıklarındaki verileri de bu yazılımlar kullanılarak değerlendirilmiştir. Depremin istasyonların X, Y ve Z koordinat eksenleri üzerindeki etkisi, hem ANOVA hem de Kruskal-Wallis testleri ile istatistiksel olarak incelenmiştir. Analizler, deprem öncesi, deprem günü ve sonrası farklı günler ile deprem gününe ait farklı saat aralıklarına göre GNSS servislerinden elde edilen koordinat değerlerinin istatiksel farklılıklarını incelemeyi kapsamaktadır. Deprem öncesi ve sonrası koordinat farklılıklarının istatistiksel olarak anlamlı olduğu özellikle Y koordinat ekseninde büyük yer değişimlerinin yaşandığı, Z koordinat eksenindeki değişimlerin ise diğer eksenlere göre daha az olduğu belirlenmiştir. EKZ1 istasyonu için yapılan saatlik analizler, konumsal değişikliklerin istatistiksel olarak anlamlı bir şekilde farklılaştığını ortaya koymuştur.
