Abstract

Abstract: Variations of the ionospheric F2 region critical frequency ( f oF2) have been investigated statistically before earthquakes during 1980–2008 periods in Japan area. Ionosonde data was taken from Kokubunji station which is in the earthquake preparation zone for all earthquakes. Standard Deviations and Inter-Quartile Range methods are applied to the f oF2 data. It is observed that there are anomalous variations in f oF2 before earthquakes. These variations can be regarded as ionospheric precursors and may be used for earthquake prediction.
