Abstract. Several major earthquakes that happened nearby Malaysia for the past decades resulted in a tectonic drift of the Sunda plate. Geocentric Datum of Malaysia 2000 (GDM2000) is affected and has shifted. This paper aims to assess the consistency of GDM2000 by computing datum shift caused by tectonic movement and reference frame effect. Daily solution coordinate of Malaysia Real-Time Kinematic Network (MyRTKnet) stations in the latest reference frame i.e ITRF2014 generated and a coordinate discrepancy between the current reference frame and publish coordinate provided by Jabatan Ukur dan Pemetaan Malaysia (JUPEM) are computed. The result shows that the datum has shifted with an average of 34.6 cm and moved with an average orientation of 111.1° toward the southeast direction. Therefore, this study will contribute to giving an overview of the current status of GDM2000.
