Abstract

North Sumatera earthquake on 11 April 2012 has occurred and some of the close countries felt the tremor. The impact was recorded by the Global Navigation Satellite System (GNSS) at the Continuously Operating Reference Station (CORS) throughout Malaysia. This paper investigates the feasibility of using Malaysia continuously operating reference stations (CORS) for short term deformation monitoring and analysis. The data quality and reliability of the GNSS are critical issues in terms of suitability and geological stability. An investigation into appropriate strategies for GNSS data processing and deformation analysis in relation to the most recent International Terrestrial Reference Frame is conducted (ITRF). Double different processing method were used to get the adjusted coordinate in daily solution. The results of deformation analyses, as well as detailed data-processing strategies, are discussed in detail, and some useful conclusions are drawn. The results demonstrate that the deformation analysis derived from regional CORS network data processing is both feasible and effective in practice. In this research the displacement of the CORS stations are between 4.47 – 0.35 magnitude. As evidenced by this example, continuous tracking data from Malaysia's CORS network (MyRTKnet) is a valuable asset that can be used to develop a technically advanced and cost-effective geoscientific infrastructure for deformation monitoring analysis.
