International journal of artificial intelligence and computational researchSummary: Ionospheric total electron content (TEC) perturbations observed for event happened on 15th January 2014 in Indonesia with magnitude of M- 4.5 on Ritcher scale are investigated. The earthquake occurred at 9:26 hours greenwich meantime (GMT). Yule-walker, covariance, modified covariance and burg parametric methods are used to find out the change in the spectrum of signals with and without disturbances in the signal. Form the analysis, it is observed that ionosphere was disturbed thrice due to the impending earthquake resulting in upraise of energy in the ionosphere at 10:13 hours LTC, 10:40 hours LTC and finally at 10:52 hours LTC, which is coinciding with that of the earthquake oocurrence. These studies in future may help in developing early warning systems for earthquakes.
