The spatial grids of the model GSM TIP in geomagnetic coordinates for setting of the different sources of ionospheric disturbances before the strong earthquake in Greece. The methods of setting of these sources: at the left—eastward electric field at height of 175 km (dark and light points—grid points with additional positive and negative potential 10 kV); in the middle—the IGWs at height of 80 km (circles mark grid points with IGWs); on the right—vertical electric field penetrated into the ionosphere at height of 175 km (circles mark grid points with 10 kV potential).
