SYSTEM FOR PROVIDING WARNINGS ABOUT EARTHQUAKES AND TSUNAMI BY ENABLING APPROPRIATE SIGNALING SYSTEMS Russian patent published in 2006 - IPC G01V1/16 G01V1/38 

FIELD: underwater geo-acoustics, possible use for providing warning about earthquake and tsunami by enabling appropriate signaling systems.

SUBSTANCE: system contains hermetic body, and also optic-electronic indicator of previously given limit value of pendulum deviation. To lower part of body receiver of seismic oscillations is connected, and to upper one - pendulum with distributed mass. Optic-electronic sensor is made in form of signal and supporting filament coils, optically connected through source of coherent light and photo-receiver into interferometer. Signal and supporting filament coils are positioned on the body mounted on sea bottom, respectively on or outside the trajectory of deviation of pendulum from balanced position, while source of coherent light and photo-detector are positioned at above-water control and registration center. Optic-electronic indicator includes optically synchronized source of coherent light and photo-detector. Photo-detector is connected by output through serially connected photo-current amplifier and frequency meter to alarm signaler. Alarm signaler is made in form of transmitter, satellite relay and ground station. Transmitter is made in form of, connected serially to output of frequency meter: generator of modulating code, phase manipulator, second input of which is connected to output of high frequency generator. Ground station is made in form of, installed serially: receiving antenna, high frequency amplifier, mixer, intermediate frequency amplifier, first multiplexer, narrowband filter, second multiplexer, low frequency filter. Second input of mixer is connected to output of heterodyne. Second input of first multiplexer is connected to output of low frequency filter. Second input of second multiplexer is connected to output of intermediate frequency amplifier. connected to output of low frequencies filter are registration block and sound signaling device.

EFFECT: increased speed and trustworthiness of transfer of warning information.
