A model of the generation of local electric fields in the atmosphere a few days before earthquakes and up to a few days after the seismic shocks is proposed. The generation of the electric fields occurs because of an increased ionisation intensity of the atmosphere at the presence of radon the concentration of which increases in earthquake preparation regions. The formation of mosaic-likely distributed regions of electric fields with intensities of 3 10**2 - 10**5 V/m and, on the other hand, large areas with increased electrical conductivity causes a series of physical effects, e.g. the occurrence of infrared emissions with specific spectrum, which may be studied using earth-based, atmospheric and satellite observations. A recently proposed laboratory experiment is discussed which is carried out to prove the theoretically predicted intensification of infrared emissions some hours-days before earthquakes.
