| Özet |
| The variability of the ionosphere is important for radio communications and ionospheric studies. In this study, the variability of the ionosphere due to seismic activity is investigated by using Total Electron Content (TEC) estimates obtained from CORS-TR Global Positioning System (GPS) stations. Two earthquakes occurred on Northern Anatolian Fault in Turkey are chosen for the purpose. The TEC data set is investigated by using Cross Correlation Coefficient (CC), symmetric Kullback-Leibler Distance (KLD) and L2-Norm for seismically active days and geomagnetically quiet days. It is observed that CC values of quiet days are highly correlated for quiet days. CC values of earthquake days decrease down to 0.2 in earthquake days. KLD values of earthquake days are 10 times greater than those of the quiet days. In order to form a proper earthquake precursor alarm signal, more earthquakes with different properties have to be investigated in the future. |
