SEISMOPRECURSORS IN SPACE AS PLASMA AND WAVE ANOMALIES

Abstract

As the result of last 10-15 years ionospheric investigations it was found that the ionosphere is a good indicator of ionosphere-lithosphere coupling processes. Ionospheric variations related to the lithosphere and crust changes are found not only after strong earthquakes but some days before the main shock. The latter variations may be considered as earthquake precursors. Amongst a variety of known ionospheric anomalies caused by a forthcoming earth-
