Abstract : Properties of infrasonic and seismic disturbances excited by low level, subsonic B-1 flights over the Arkansas River Valley near La Junta, Colorado are measured and studied for different wind conditions. The study emphasizes the role seismics and infrasonics might play to detect and track aircraft overflying a distributed network of pressured sensors and seismometers. The work concludes that carefully sited and calibrated seismic nodal elements, operating at low data rates, have a high potential to provide timely azimuth information for tracking. Keywords: Aircraft detection, Infrasonic seismic networks, Aircoupled, Subsonic flight detection, Aircraft tracking, Infrasonics.
