Abstract

A study on the earth's crust movement and the effects of the earthquake on the tectonic belts of Peninsular Malaysia have been carried out using GPS data. The GPS data from five Real Time Kinematic (RTK) stations within Peninsular Malaysia have been analyzed to study the movements of two major tectonic belts of Peninsular Malaysia namely the western belt which is represented by Behrang and UPM Serdang stations and the central belt by Bentong, Jerantut and Temerloh stations. The GPS data recorded from 2005 to 2010 were analyzed based on horizontal and vertical displacements of the respective RTK stations. The accumulated horizontal displacements of the GPS data recorded from May 2007 to December 2010 shows that the western belt has shifted around 5.59 to 23.18 cm towards southeast in counter clockwise pattern while the central belt moved around 0 to 19.45 cm to the northwest also in counter clockwise manner. Meanwhile, the Bentong station which is located in the Bentong-Raub suture zone of the central belt has shifted 23.43 cm, also towards southeast and more or less in similar direction with that of the western belt. Although the accumulated annual movement of the five MyRTKnet stations generally show similar directions, the study revealed that the movement for most of the GPS stations, except Temerloh, occurred in different directions in certain months such as in July 2007 (Jerantut), January and May 2008 (Behrang), September and March 2009 (UPM Serdang and Jerantut) and November 2010 (Bentong). These differences in direction of movements are interpreted due to the influence of reactive faults in the respective stations which are stimulated by several large earthquakes that occurred in Indonesia from 2005 to 2010.
