Tomography technique is one method in geosciences adapted from medical field like CT Scan and MRI. In medical field, tomography is used to describe human’s body condition but in geoscience it is used to describe subsurface of the earth, like passive seismic tomography. Subsurface description like velocity data that expressed in tomogram is a result of inversion from travel time and ray tracing data. Tomography is done in various grid model (regular and irregular grid). Irregular grid give a better tomogram result, it is caused by it does not need big data of hypocenter or station. The distribution of grid also showed the good propagation model of ray tracing that influenced the tomogram result.
