Eruption of Mount Lokon has the potential to cause danger to the community. The study of the ionospheric disturbances triggered by Lokon activity is very important to determine eruptive behavior. TEC anomaly before eruption is succesfully detected using correlation methods. Based on GPS TEC data from the GNSS satellite it was concluded that the TEC anomaly occurred three days before the eruption on July 14 th , 2011. Using leveling method and polynomial technique, eruption effects on ionosphere were be determined. Eruption on July 2011 caused ionospheric disturbance. These results will be important considerations in decision making related to disaster mitigation
