Radiophysical methods for monitoring heliogeophysical and seismic conditions are used for creating a real-time information support of high-reliability shortterm prediction of the location and time of very strong earthquakes, detection of high-power underground and atmospheric nuclear explosions, and prediction of short-wave radio signal propagation conditions determining the performance of communication and radar systems.
