Harnessing high-performance computers and accurate numerical methods to better constrain physical properties of Earth's interior is rapidly becoming one of the most important research topics in exploration and global seismology. We use spectral-element and adjoint methods to iteratively improve 3D subsurface images ranging from exploration to global scales. The spectral-element method, a high-order finite-element method with the advantage of a diagonal mass matrix, is used to accurately calculate three-component synthetic seismograms in complex 3D Earth models.
