SYSTEM FOR REPEATED ALERTING ON TSUNAMI WAVES IN DEEP OCEAN Russian patent published in 2011 - IPC G01V9/00 G01V1/38 

FIELD: physics.

SUBSTANCE: system for repeated alerting on tsunami waves is in form of units which detect pressure fluctuations and transmit tsunami warning data. The unit which detects pressure fluctuations lies at the bottom and the unit or container 1 with several radio transmitters 2 for transmitting warning data on tsunami waves is submerged in the surface region. Both units work in standby mode and upon fluctuations typical for destructive tsunamis, an instruction is transmitted from the unit detecting pressure fluctuations to an acoustic signal receiver 4, on which one of the radio transmitters automatically disconnects from the container and emerges on to the water surface, after which a radio signal warning on a tsunami and coordinates of the system are transmitted to a satellite or coastal station.

EFFECT: cutting the time between tsunami wave detection and alerting to not more than a few minutes, and a reusable principle of operation of the system while maintaining simple design and use overall.
