Detecting Vehicle Movement with Seismic Observations
The detection and characterization of signals related to the transfer of material remains a complex problem in forensic seismology. Such signals can occur in noisy environments where it becomes increasingly difficult to isolate associated signals from other cultural noise. We took advantage of a rich seismic dataset from a 12-day controlled experiment focused on recording signals generated by industrial-sized vehicles entering and exiting the High Flux Isotope Reactor (HFIR) and Radiochemical Engineering Development Center (REDC) complex. Ground-truth data was collected during the experiment using low- and high- resolution GPS and video camera footage to track the vehicle position and configuration. We analyzed 24 hours of seismic data using a single station (Station Number 264126) and implemented a classic seismic detection method to detect, identify and measure signals generated by the vehicles operating on a fixed transfer schedule.
