Abstract :
The paper presents the authors´ view on the TEC (Total Electron Content) disturbances considered as seismo-precursors. The “traditional” pre-earthquake signatures are extended with the terminator-related effects: the coming of the terminator and subsolar point triggers the shift and migration of the TEC anomalies towards the night-zone, followed with their shape modification and full destruction at the near-noon hours at the near-epicenter and geomagnetically conjugated regions.
