Occurrence of space VLF due to the earthquake events

In recent years many research has pinpointed possible precursory signs that occur before an earthquake. One of the precursory signs that associated with earthquake (EQ) is the electromagnetic phenomena. Among these, the VLF electromagnetic emission is recognized as one of the most promising candidates for short-term earthquake prediction. This project focuses on revealing the perturbation of the VLF signals during earthquake event. In order to reveal possible earthquake precursor though the changes of VLF signal, Northern Sumatera Indonesia earthquake that happened on 7^th April 2010 is chosen as a study case. The observation was made on the day of the earthquake event occur. VLF data deployed from system called Atmospheric Weather Electromagnetic System for Observation Modeling and Education (AWESOME) through its VLF receiver. Matlab is used to simulate the data. The result shows that strong correlation between VLF and determination of earthquake precursors.
