| Zusammenfassung |
| Some years ago, 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 shock was proposed. In the model, the generation of the electric
fields occurs because of an increased ionisation intensity of the atmosphere
in the presence of aerosols. The generation of the electric field is the
result of the fact that the larger aerosols, which are mainly negatively
charged, have a larger velocity of gravitational precipitation than the
smaller, which are mainly positively charged aerosols. The ionisation in such
atmospheric regions is caused by radon, the concentration of which increases
in earthquake preparation regions. The formation of mosaic-likely distributed
areas of electric fields with intensities of 3 × 102 – 105 Vm−1
and, on the other hand, large areas with increased electrical conductivity
cause a series of physical effects, e.g. the occurrence of infrared
emissions with a specific spectrum, which may be studied using earth-based,
atmospheric and satellite observations. In the present paper, the model of
the generation of local electric fields is further developed, improving the
description of the force balance on the aerosols in the atmosphere. A
recently proposed laboratory experiment is briefly discussed, which is
carried out to prove the theoretically predicted intensification of infrared
emissions some hours-days
before earthquakes. Besides the experiment described, it
will be operated on Kamchatka
in the near future to scan mosaic-likely distributed regions of
electric fields in the atmosphere during earthquake preparation times. |
