In the pursuit of increasingly accurate seismic event modeling, incorporating anisotropy is critical for accurately describing the Earth’s subsurface structure. This thesis explores the Instantaneous Time Mirror (ITM) method for numerical wave reversal in anisotropic media, implemented within the open-source simulation software SeisSol. The study analyzes seismic waves in both forward and backward directions, achieving wave refocusing under varying velocity conditions to recreate the initial source event. The ITM approach is validated against benchmarks and applied in a real-world context around Mount Zugspitze.     «
