- Upward migration of gas/liquid substrate matter (bubble)could
lead to ousting of the hot water/gas near the ground surface
and to origin of EQ itself in the strength-weakened area.
2. So time and place of the bubble appearance could be random
values, but EQ, geochemistry anomaly and microfracturing
(EM, AE anomalies) are casually connected.
3. Atmospheric perturbation of temperature and density could follow
preseismic hot water/gas release resulting to generation of
internal gravity waves with periods 10minutes-2 hours.
4. Seismo-induced AGW could lead to modification of the
ionospheric turbulence and to a change of over-horizon radio-wave
propagation in the atmosphere , reflection of LF wave from the
lower ionosphere and ULF emission depression inside middle
