Es-spread effects ionosphere earthquakes
2009/12/29
In the present work, phenomena in the ionosphere are studied, which are connected with earthquakes (16 events) having a depth of less than 50 km and a magnitude M larger than 4. Analysed are night-tim...
On the possible influence of radon and aerosol injection on the atmosphere and ionosphere before earthquakes
possible influence radon and aerosol injection atmosphere and ionosphere earthquakes
2009/12/29
A model of the generation of pulses of local electric fields with characteristic time scales of 1–10 min is considered for atmospheric conditions above fracture regions of earthquakes. In the model, i...
DC electric field amplification in the mid-latitude ionosphere over seismically active faults
DC electric field amplification mid-latitude ionosphere seismically active faults
2009/12/28
DC electric field in the ionosphere above seismically active regions can be formed in a process of external current insertion into the atmosphere-ionosphere electric circuit. This current arises as a ...
