METHOD OF DETERMINATION OF TSUNAMIGENESIS OF OCCURRED SUBMARINE EARTH MOVEMENT Russian patent published in 1995 - IPC

FIELD: seismology. SUBSTANCE: magnitude and coordinates of epicenter of occurred submarine earth movement are determined at family of seismic stations by its signals. Submarine earth movements with magnitude M≥7 are considered tsunamigenetic. Hydroacoustic signals of this submarine earth movement are recorded in submarine audio channel by hydrophones, are transmitted to coastal posts, amplified and sent over radio channel to seismic stations. Spectral analysis of hydroacoustic signals in high-frequency range (100-400 Hz) is conducted and if signal exceeds background magnitudes in high-frequency (100-400 Hz) range of spectrum possibility of generation of tsunami is judged by it. EFFECT: enhanced authenticity of determination of tsunamigenesis of occurred submarine earth movement.
