Abstract

Positive and negative TEC (Total Electron Content) anomalies were calculated by investigating the TEC disturbance effects on the Earth's ionosphere, a natural plasma, caused by the 6.6-moment magnitude earthquake that occurred off the AegeanSea at 11:51:24 on October 30, 2020. By examining the effects of solar and geomagnetic activity on ionospheric disturbance, TEC anomalies that are likely to be related to the earthquake were determined. TEC data; obtained via three ground-based ionosondes (one selected outside the earthquake preparation zone for comparison) and five satellite-based IGS stations. The linear and polynomial correlations between the latitude and longitudinal distances to the earthquake epicenter of the TEC anomalies, which were determined to be caused by the earthquake, were obtained by various statistical operations.
