Abstract

In this article we studied the variation of Maximum Electron Density (NmF2) concentration in the ionosphere calculated by earth positioning ionosonde around the time of strong seismic shock. We used NmF2 data of two stations Athens and Sanvito. We calculate Karl –Pearson coefficient of correlation. Results of the study showed that Karl- Pearson Coefficient get maximum disorder before two days from the seismic shock. It may be due to the generation of seismic wave during earthquake, which propagate upward and perturb the F-region ionosphere. Results may be beneficial in seismic precursor study.
