Recently, Total Electron Content (TEC) data, obtained from Global Navigation Satellites Systems (GNSS) receivers, are increasingly being used to detect seismo-ionospheric anomalies. In this study, Global Positioning System – Total Electron Content (GPS-TEC) data were used to investigate ionospheric abnormal behaviours prior to the 2005 Northern Peru earthquake (5.674 S, 76.409 W, September 26, 2005, 01:55:37 UT, Mw:7.5). The data obtained from three International GNSS Service (IGS) stations near the epicentre of the earthquake were used to detect ionospheric anomalies before the earthquake. Solar activity (F10.7), geomagnetic storm (Kp) and geomagnetic activity (Dst) index values which are both related to space weather conditions, were used to analyze these pre-earthquake ionospheric anomalies. Analysis results revealed that anomalies occurred and the possible ionospheric VTEC anomalies associated with the earthquake obtained four to nine days before the Northern Peru earthquake. This study is supported by TUBITAK, Environment, Atmosphere, Earth and Marine Science Research Support Group (CAYDAG) grant no. 116Y109.

Son zamanlarda, Global Navigasyon Uydu Sistemleri (GNSS) alıcılarından elde edilen Toplam Elektron İçeriği (TEC) verileri, sismo-iyonosferik anomalileri tespit etmek için giderek daha fazla kullanılmaktadır. Bu çalışmada, 2005 Kuzey Peru depremi öncesinde iyonosferik anormal davranışları araştırmak için Küresel Konumlandırma Sistemi- Toplam Elektron İçeriği (GPS-TEC) verileri kullanılmıştır (5.674 G, 76.409 B, 26 Eylül 2005, 01:55:37 UT, Mw:7.5). Deprem merkez üssüne yakın üç Uluslararası GNSS Servisi (IGS) istasyonundan elde edilen veriler deprem öncesi iyonosferik anomalileri tespit etmek için kullanılmıştır. Deprem öncesi iyonosferik anomalileri incelemek için, uzay iklim koşullarına bağlı güneş aktivitesi (F10.7), jeomanyetik fırtına (Kp) ve jeomanyetik aktivite (Dst) indis değerleri kullanılmıştır. Analiz sonuçlarına bakıldığında, anomalilerin ortaya çıktığı ve depremle ilişkili muhtemel iyonosferik VTEC anomalilerinin, Kuzey Peru depreminden dört ila dokuz gün önce meydana geldiği görülmüştür. Bu çalışma TÜBİTAK, Çevre, Atmosfer, Yer ve Deniz Bilimleri Araştırma Destek Grubu (CAYDAG) tarafından 116Y109 nolu proje ile desteklenmektedir.
