Abstract
This is an experimental study of the features of infrasound formation durin g the operation of high-power seismic vibrators. The infrasound is shown to be radiated into the atmosphere by a 150 m region adjacent to the seismic vibrator. Annual monitoring of the vibrator-induced infrasound at a distanc e of 50 km indicates that the times of arrival, amplitudes, and mode compos ition of infrasound signals fall in a broad range and that the atmospheric duct of these signals changes rapidly.
