Total Electron Content (TEC) perturbations observed for event happened on 15th January 2014 in Indonesia with the magnitude of M ~ 4.5 on Richter scale are investigated. The earthquake occurred at 9:26 h Greenwich Mean Time (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. From 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 h LTC, 10:40 h LTC and finally at 10:52 h LTC, which is coinciding with that of the earthquake occurrence. These studies in future may help in developing early-warning systems for earthquakes.
