Bu sapmalar ana şokun hazırlık aşamasına ait önemli bilgileri içermektedir. Bu nedenle Dobrovolsky Dairesi içerisindeki Swarm uydularına ait 06 Ağustos 2022 ile 09 Şubat 2023 tarihleri arasındaki manyetik anomaliler dış kaynaklı manyetik etkileri (güneş rüzgarları, manyetik fırtınalar ve atmosferik elektrik akımları) kapsamayacak şekilde filtrelenmiştir. Bir sonraki aşamada verinin zamana göre 1’inci türevi alınmış ardından uzun dalga boylu trend veriden giderilmiştir. Filtrelenen verideki anomali bölgelerini belirlemek için kayan karelerinin ortalama karekökü (RMS) penceresi uygulanmıştır. Son olarak da kümülatif manyetik anomali değişim grafiği çizdirilmiştir. Bu grafik kapsamında depremden önce manyetik alanın X bileşeni için önemli bir anomali değişimi saptanamamış iken Y, Z ve F bileşenlerinde depremin hazırlık aşamasına ait kendisini tekrarlamayan anomaliler tespit edilmiştir.</p></abstract>

                            <p>On February 06, 2023, there were three earthquakes with magnitudes of Mw=6.7, Mw=7.5, and Mw=7.8, which caused deviations in the magnetic anomalies measured due to Litosphere-Asthenosphere and Ionosphere Coupling (LAIC) prior to the earthquakes. These deviations contain important information related to the preparation phase of the main shock. Therefore, magnetic anomalies from Swarm satellites within the Dobrovolsky Circle between August 06, 2022, and February 09, 2023, were filtered out to exclude external magnetic effects (solar winds, magnetic storms, and atmospheric electric currents). In the next stage, the first derivative of the data was taken with respect to time and the long wavelength trend was removed from the data. The root-mean-square (RMS) window of moving squares was applied to identify anomaly regions in the filtered data. Finally, a cumulative magnetic anomaly change graph was plotted. According to this graph, a significant anomaly change was not detected in the X component of the magnetic field before the earthquake, while repeating anomalies related to the preparation phase of the earthquake were identified in the Y, Z, and F components.</p></trans-abstract>
