摘要：Ionospheric storms are general perturbations of the upper atmosphere which affect space- and ground-based technological systems. These storms are triggered by an increased flux of energetic electrons that are released by the Sun. Extreme solar activity may originate from Coronal Mass Ejections (CME) and solar flares that may result in ionospheric storms. The ionospheric anomalies usually happen in D-layer, E-layer and F-layer. They may be observed from 1 to 10 days prior to the earthquake and stay until 1 to 2 days after the earthquake. Comparatively the ionospheric precursors, the geomagnetic indices Dst, Kp and AE-indexes have been selected for pre-earthquake disturbed states. In the present study we are taking into account the existence of correlational changes in the ionosphere before strong earthquakes triggered by geomagnetic storms and we consider the subsequent impact on the environment. The statistical analysis presents the ionospheric precursors during geomagnetic storm conditions which occurred during March 2018 and correlated with them strong earthquakes.
