Abstract

One of straits in Indonesia that have activity active tectonic is Sunda Strait. This Strait it is at meeting two tectonic plates, that is Eurasia and Indo-Australia. Meeting both plate of zone form subduction that have direction and type slab that not uniform and different each other in Sunda Strait region. Interaction from meeting both plate referred, alongside Sumatera island generates fault that recognized with Patahan Sumatera. Characteristic of earthquake source zone that existed in Sunda Strait is earthquake source subduction that associated become some active faults. One of methods that applied to see deformation was using GPS either through episodic or continuous that have high precission till some millimeters (mm). By determining slip rate estimation and making of deformation model then could be determined activity that happened in Sunda Strait. Modelling were referred to see residue between vector of GPS and model vector. Slip rate in Sunda Strait that has been associated in segment of Semangko Fault (SF) was 2.5 cm/year, with depth 8 km and mechanisms dextral, that gave result GPS continuous data were not far significant with some former research that is 1.8 – 2.1 cm/year. Subduction model by using dislocation formula Okada and giving coupling rate equal to 25% and post seismic as 6 cm/year, gave result that deformation model that produced near with GPS continuous data.
