This thesis presents a numerical investigation of the wave reversal technique using the Instantaneous Time Mirror method in the simulation software SeisSol. Earthquakes produce two different kinds of waves i.e., P- and S-waves. The focus of the study is to develop a novel approach to accurately determine the source of an earthquake by analyzing the time evolution of the seismic waves in both the forward and time-reversed directions. We analyse the application of an Instantaneous Time Mirror (ITM) on a planar travelling wave and spherical waves produced by point sources. We then refocus each of the P- and S-waves separately to the source location. We demonstrate the application of the ITM on different types of point sources and show that the ITM is able to refocus the waves to the source location.     «
