摘要：

Recent investigations show that there are a number of specific effects at F-region altitudes which could be considered as earthquakes ionospheric precursors. One of such effects is a night-time increase of F2 critical frequency 1 to 2 days before the seismic event. Distortions of the electron density profiles which occur at the same time are investigated in this report. N(h)-profiles obtained from vertical soundings near the epicenter differ noticeably from IRI predictions.
