| description | Many studies on the pre-earthquake involving various methods have been
conducted to understand the earthquake activity. The Lithosphere-Atmosphere-
Ionosphere Coupling (LAIC) effect describes what physical processes are involved
prior to an earthquake. Southeast Asia is a region where earthquakes have a high
frequency to occur, and the earthquake’s studies in this region still lack and poorly
understood. Therefore, this study aims to understand the pre-earthquake behaviour by
investigating the behaviour of the geomagnetic field and the components before an
earthquake. The geomagnetic field data is collected using space borne sensors and
ground sensors. Satellite data will be collected by the CHAMP and Swarm satellites,
while MAGDAS will collect ground sensor data. This study is based on the major
earthquakes (M>6.5) that happened in Southeast Asia for eleven years, from 2008 to
2018. Two weeks prior to every listed earthquake, the data was collected, filtered, and
distinguished from any unrelated geomagnetic anomalies such as solar activities and
magnetic storms. Based on the result, at least one disturbed profile would appear
before a major earthquake. The dominant component that showed the most significant
anomalies on every disturbed profile was the y-component and N-component for
satellites and MAGDAS data, respectively. Lastly, the mass collecting data from both
satellite and ground sensors hopefully will be helpful to the improvement for the future
real-time earthquake precursor in the Southeast Asia region. |
