Аннотация:The existing theories of the emergence of anomalous electromagnetic emissions and impulses in ULF frequency range preceding earthquakes are critically revised. For a better physical insight simplified theoretical estimates of the expected effects have been made. The principal results of the existing numerical models are reproduced in a much simpler way without mathematical complexities. The considered phenomena comprise electrokinetic effects, seismo-inductive effects, large-scale current systems produced by dislocations or water evaporation, geomagnetic inductive effects caused by acoustic impulses from micro-cracks, plasma oscillations, etc. It is demonstated that none of the theories can be fully adopted because of essential intrinsic difficulties.
