Abstract

The Sumatra Island is located between two tectonic plates; the Indo-Australia Plate and the Eurasian plate. The intensity of the earthquakes is very large on the island because of this, especially along the western coastal area. On the 2002 to 2008 period, many large earthquakes that caused casualties and damage to the environment. These phenomena shows that the studies of the deformation patterns of the Sumatra island is required. The studies are required for disaster mitigation plans in the future. The deformation patterns of the earthquake can be observed with GPS (Global Positioning System) observation. The data that is being used for Sumatra earthquake is the Sumatran GPS Array. The software that is used for the Sumatran GPS Array data of the Sumatra Island is the Gamit 10.4. From the data processing, it can be concluded that there are displacements of the nations can be used if the outlier data has been erased. From the station displacement coordinates, we can obtain the displacement vector of all of the station before, during or after the earthquakes. From the displacement vector values, the values of the strain that occurs along the Sumatra Island can be estimated. From the strain data, the accumulated value of strain from 2002 to 2008 can be obtained. Finally it can be predicted potential area for next earthquake.Keywords:
