Physical models of coupling in the lithosphere-atmosphere-ionosphere system before earthquakes

摘要: The most important models of coupling in the lithosphere-atmosphere-ionosphere system are considered. In some these models, it is assumed that atmospheric acoustic and gravity waves (AGWs), which propagate through atmosphere reach ionospheric altitudes (resulting generation electric field disturbances modulation charged particle density), generated near-Earth over earthquake preparation region. other originate owing to modification fields currents due processes lithosphere or atmosphere. It seems impossible stress on only one model reject remaining because characteristic spatial scales effects observed ionosphere before earthquakes vary from 200–300 km several thousand kilometers, times minutes days. We can assume there physical mechanisms by lithosphere-ionosphere actually implemented.
