Monitoring motion of Mount Kinabalu and its surrounding using high precision GNSS / Noorhurul Ain Othman

Sabah is situated on the Sunda Plate in a tectonically active region of Borneo, bordered by active Eurasian, India-Australian, and Philippine-Pacific plates, making it vulnerable to seismic activity. In Sabah also has the highest mountain which is Mount Kinabalu, with a summit height of 4095 meters. Sabah, which is located in the semi-stable South China Sea Basin, is influenced by active mobile belts in Sulawesi and the Philippines. Because earthquakes happen every so often, it's crucial to look at the ground surface motion and the station's displacement as a result of the shaking. Therefore, the goal of this study is to investigate motion that occurs in Mount Kinabalu and surrounding Mount Kinabalu using High Precision GNSS. The MyRTKnet station was used in this study to measure ground deformation movements in horizontal and vertical components. MyRTKnet stations have been processed using GIPSY software using data from 2011-2020 to find out the time series and strain rate of each station in Sabah. However, from the analysis obtained from strain rate, Sabah has moved towards the southeast of Sabah with a velocity of 22.9-31.7 mm/year. Therefore, the strain map will make it possible to classify seismic zones, which is helpful for managing geohazards.
