Seismoacoustic Source Localization: Case Study from AES Tennessee Explosion

Description: 

Accurate localization of explosions is crucial for understanding their impact and for effective monitoring of both natural and anthropogenic activities. This study focuses on the seismoacoustic location of an explosive event that occurred at the Accurate Energetic Systems manufacturing plant in Tennessee on October 10, 2025. We investigate the efficacy of combining reverse time migration (RTM) techniques with traditional arrival-time based methods to enhance the precision of source localization. By employing RTM, we back-project seismic and infrasound waveforms through their respective media, allowing for a comprehensive analysis of the energy release. To address the challenges posed by discrepancies in waveform characteristics between seismic and infrasound signals, we implement enveloped waveforms, which facilitate a more robust integration of the two data types. Similarly, we utilize arrival-time data from the same set of stations to provide complementary seismoacoustic location solutions. Our results demonstrate the effectiveness of joint seismoacoustic solutions in accurately locating the explosive event, highlighting the potential for improved event discrimination and characterization. This work contributes to the ongoing efforts in global monitoring and provides insights into the dynamics of explosive sources. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525.
