On 26 decembers 2005, earthquake strike with scale 9.2 richter espoused with tsunami that bump into Aceh region and vinicity. Then known the centre location of earthquakes to happen in 50 km northside Simeulue island with depth 30-40 km alongside subduction region and be to first earthquake with magnitude on 8 in 200 year this (Lay et al., 2005). To detect potential source from earthquake at Simeulue region in period to come, more deepen erudition from major geology structure in region is needed.<p> <br /> <br /> <br /> <br /> <br /> <br /> <br /> To detect geology structure with watchfulness good resolution is done with seismic method. Seismic reflection is used to shallow modelling with high resolution, while seismic refraction is worn to major structure modelling with deep depth.<p> <br /> <br /> <br /> <br /> <br /> <br /> <br /> Here we will present subduction model result from sesimic refraction at Simeulue region that show 4 regions that divided to follow geology structure that occurs. That is ocean crust condition where we didn't find diabase dikes layer, the drastically reduced velocity at oceanic crust that guessed to be volcanism activities, accretionary zone and dip ofsubducted plates slopes around 100.
