Observation of ionospheric disturbances for earthquakes (M>4) occurred during June 2013 to July 2014 in Indonesia using wavelets

Abstract

Seismo-ionospheric perturbations are extensively studied for large earthquakes occurred over various parts of the world. Specific signatures of these natural events are observed in the Total electron content (TEC) data prior to their occurrence. Analysis of these natural disasters occurring at a specific location will help in their accurate detection and prediction. In this paper the Java region of Indonesia comprising of a belt of volcanic mountains, where a considerable number of events to analyze their characteristics in the ionosphere are considered for study. This region of Indonesia has an International Global Navigation Satellite System Station at Bakosturnal, Indonesia. Vertical total electron content data on the earthquake day is analyzed for 13 events occurred during June 2013 to July 2014.
