Global seismic adjoint tomography

Categories: Current Research

Details

Large earthquakes produce seismic waves which are recorded globally by sensitive seismometers. ​Using such seismic broad-band data from all over the world, we conduct global seismic adjoint tomography to refine 3D seismic models of the entire planet Earth. This necessitates fast and highly accurate forward and adjoint solvers together with large HPC facilities. We therefore investigate and develope spectral-element codes to advance the state-of-the-art in global seismic tomography.
