AbstrakA conventional way to determine the hypocenter of earthquake is usually calculated by a global velocity model. however, this way is not completely valid because each area has a different rock structures. based on this model, we need to calculate velocity model to each region. in this study, we calculated velocity model for aceh area. the model is an improvement of velocity model that developed by international association of seismology and physics of earth’s interior (iaspei) i.e. iasp91. in order to gain the velocity model, we inverted arrival time data of the earthquake that facilitated by velest3.1 cod (kissling, 1995). the data were collected from mata ie (bsi), meulaboh (mlsi), langsa (lasi), tapaktuan (tpti), lhokseumawe (lhmi), and kutacane (kcsi) stations in aceh province . the results show that the final model is faster than the initial model i.e. iasp91. using the final model, we have been able to relocate the hypocenter almost precisely. moreover, it obtained correcting
