Seismic tomography is a method that is widely applied to obtain seismic velocity structures below the surface. This method is applied to various cases, from global to regional scales, as well as local scales such as in the case of volcanoes, geothermal areas and underground mining. Until now, the grid form that is still widely used is the regular grid form. With a very rigid grid shape, it will be more difficult and inflexible to model the geometry of certain geological models that are very varied, even though mathematically there is no reason to avoid certain grid shapes and sizes. In order to minimize the uncertainty of the subsurface geological model grid, we developed a script to perform seismic tomography where the shape and size of the grid can be made irregular based on the Voronoi diagram. The number of grids in the inversion process can also adaptively increase or decrease based on the number of the raypath data. We then applied it to the synthetic crosshole tomography data and compared the results with the regular grid. With the irregular shape and size of the grid, better inversion results are obtained and are more suitable with the synthetic model. [ABSTRACT FROM AUTHOR] |
