%X Precise determinations of ionospheric anomaly variations associated with
earthquakes require the elimination of other sources of ionospheric
variabilities like ionospheric storms, geomagnetic perturbations or geophysical
noise. However, revealing the seismo-ionospheric anomalies when the ionosphere
is known to be a complex and nonlinear system is of utmost importance. To overcome
this constraint, Hilbert-Huang transform (HHT), which is a far better technique
for both nonlinear and non-stationary system like ionosphere, was applied
together with the cross correlation coefficient method to a 7.0 magnitude
earthquake that occurred in Mozambique on 23rd of February, 2006. Three
Stations (two within the earthquake preparation zone) with hourly data of f0F2
for one month were used for the study. The results clearly revealed anomalies
that are as a result of the earthquake. These were first noticed 10 days and
another 3 days before the occurrence of this large earthquake.
