FIELD: mining. ^ SUBSTANCE: proposed station comprises hardware module, satellite communication and navigation system unit, analyser unit, control units and power supplies. Said station incorporates vertical string of hydrophones. Analyser unit can detect super low-frequency amplitude modulation of hydroacoustic signals, i.e. signs of large earthquakes, isolate pulsed signals by amplitude, repetition rate, duration and speed of seismic wave edge rising and that of T-waves of large earthquakes, i.e. signs of tsunami. ^ EFFECT: higher validity of forecast. ^ 4 dwg |
