Abstract: The study is devoted to solving the problem of recovering the trajectory of a seismic source moving underground. The Time Reversal Mirror (TRM) method, which is based on the principle of reversibility of wave processes in media without attenuation, is proposed as a solution.
In this paper, different approaches to source trajectory recovery and visualisation are investigated. The algorithms are tested on synthetic data. The results show that TRM is an effective approach to accurately reconstruct the trajectory of a moving source, even when the observational data are incomplete.

Keywords: wave propagation, seismic source, numerical modeling, Time Reversal Mirror.
