During the Mw9 Tohoku-Oki earthquake, gradual increases in both ionosphere total electron content (TEC) and geomagnetic declination signals were observed, start
Determination of the correlation between the energy-density changes in geomagnetic field and seismic events is a challenging scientific topic that allows the st
The aim of this study is to check if there is a relationship between the seismic activity and the whistlers observed by the micro-satellite DEMETER. Whistlers a
