Seismogenic electromagnetic radiation in optical and infrared range

It is shown that the variations of the Earth electrostatic field before the strong earthquakes may heat up electrons in the E-ionosphere. The latter excite the long-lived vibrations of molecular nitrogen. Which resonantly transfer the energy to the electron excitations of sodium atoms. The increase in the sodium doublet intensity can be detected in the night sky spectrum. The electrons can also populate the surface levels of dusty particles in the E-ionosphere. The surface electron- ion recombination results in appearance of highly excited atoms. These processes contribute also in the infrared range of the night sky spectrum.
