Abstract. Using dense networks of GNSS receivers, an analysis of the ionospheric responses to two underground explosions with a magnitude less than the existing threshold for detecting the ionospheric response to earthquakes was carried out. It is shown that when regestering these responses, it is necessary to take into account the possible anisotropy of the propagation of atmospheric disturbances at ionospheric altitudes due to both large-scale wind structures and the inclination of the geomagnetic field. Taking these factors into account makes it possible to reduce the magnitude threshold (compared to that established for earthquakes) of impulse lithospheric sources (explosions, volcanic explosions), the response to which can still be detected in the ionospheric total electron content variations.
Key words: ionosphere, GNSS sounding, artificial ionospheric disturbances, underground explosions.
