Re-constructing strain map in Malaysia

Sundaland plate experiencing significant crustal deformation due to series of major earthquakes that might reactivate local old and active faults. Several earthquake and tremors struck part of Peninsular Malaysia and Sabah has resulted in damages and causality. The situation has embarked in the need of crustal deformation monitoring. Besides several studies has been conducted however it undergoes a difficulty to combine long-term crustal deformation analysis. This study aims at constructing a crustal deformation in the form of regional seismic strain map in Malaysia. Crustal velocity field by using 1 year of Global Positioning System (GPS) data as quantified by 80 sites of Malaysia Real Time Kinematic Network (MyRTKnet) has been utilised to generate the strain map. Finally, site interpolated velocities will be conducted to demonstrate pattern seismic strain rate in Malaysia. From the result, the changes of strain rate pattern have been properly analysed to identify old and active fault
