Abstract

Earthquakes will form and propagate atmospheric waves, rayleigh waves, acoustic waves and gravity waves. When acoustic waves reach the ionosphere, this affects the ionospheric electron density that can be known from GNSS signals, this disorder is commonly called CID. Electromagnetic waves transmitted by GPS satellite signals that pass through the ionosphere will cause a delay in time, from this data can be used to detect the presence of ionospheric variations through TEC values. In this study an analysis of ionospheric changes due to the earthquake that occurred in Lombok Regency and Donggala Regency. The result of the analysis show that the value of ionospheric disturbance from 5 August-28 September 2018 was around 0.19 TECU-0.56 TECU.
