Seismogenic ionospheric perturbations for a seismic hazard occurred on 23rd December 2013 in Indonesia are analyzed. The earthquake magnitude is 4.5 on Richter scale. The quake happened at 1:28 h local time coordinate. The total electron content data on occurrence day is collected from IGS System service station, BAKO Indonesia. In the present paper, Welch and Burg methods are implemented on earthquake day data. These two algorithms are implemented both on perturbed and unperturbed VTEC data. Enhancement in ionosphere is seen at the 13.84 h LTC in the ionosphere is identified by using these two methods.
