In the pursuit of increasingly accurate seismic event modeling, anisotropy is crucial for describing the Earth's subsurface structure. This thesis investigates the numerical wave reversal technique for anisotropic media using the Instantaneous Time Mirror method, implemented within the open-source simulation software SeisSol. The study analyzes seismic waves in both forward and backward directions, achieving refocusing with and without constant velocity to induce a collapse at the initial source point. The implementation is validated against a benchmark and demonstrated in a practical context around the Zugspitze region.
