N2 - The 2018 Mw 7.5 Palu earthquake occurred along the Palu-Koro segment devastated Central Sulawesi, Indonesia. The Palu-Koro fault is considered as a plate boundaries between of three major tectonic plates. Couples space geodesy measurement has been conducted to characterize the crustal activity of the Palu-Koro fault based on secular velocities pattern. However, several non-secular deformation observed and need to be considered to obtained actual secular deformation. Here, we conducted data-driven time series decomposition of Global Positioning System (GPS) observation. We used earthquake catalogue data to drive decomposition recognize the co-seismic offset and respective post-seismic deformation. We obtained precise secular motion on WATP, P14P, PALP, and TOBP sites where the direction changing from eastward toward northeast.
