Located in the junction between Australian Plate, Eurasian Plate, and Phillippines Plate and Pacific Plate, causing Indonesia has high tectonic activity. In eastern Indonesia some block and active fault are generated because convergence between plates in there. Tectonic block as one of deformation phenomenom due to the interaction of between plates can be understood by using strain analysis. Strain analysis shows the change of position, shape and dimension from an object. This research use 80 GPS from previous study by Koulali et al, (2016) and some additional data in this research to calculate strain rates to find relation between tectonic activity and strain rate in Banda Sea, and to identify block boundary. The GPS data are processed using GAMIT/GLOBK software to obtain time series in each station. Strain rates are calculated using softwae package named grid strain which calculate strain based on interpolation using discretized geodetic measurement resulting strain rates in grid system. The data distribution and algorithm in grid strain influence the result of strain rates from grid strain. The result from strain calculation is in ranges -16,421x10-8 to -0,194x10-8 for shortening parameter and 1,653x10-8 to 18,92x10-8 for extension parameter. From strain analysis conclude that strain rates can identify tectonic activity but not accurately for block boundary. Banda Block, Timor Block, and Bird’s Head Block has different strain pattern especially in their boundary. Timor and western part of Banda Block dominated by shortening according to the back arc located in there. Banda sea have low strain rates both in shortening and extension due to collision effect between Australia aand Eurasia Plate, meanwhile in the western Bird’s Head have higher shortening and in the eastern Bird’s Head has higher extension. For further analysis in determine block boundary need some additional data such as density of GPS sites, earthquake, and gravity data.
