METHOD AND APPARATUS FOR PREDICTING TSUNAMI AND DETERMINING EPICENTRE THEREOF Russian patent published in 2013 - IPC G01V1/38 

FIELD: physics.

SUBSTANCE: apparatus for realising said method includes a seismic station, spatially distributed underwater channels with hydrophones, and a radio channel connected to the seismic station. Each of the spatially distributed underwater channels with radiophones includes: a connected group of separate buoys with radio communication modules, a neutral buoyancy conducting rope, a power supply and data processing module, two vertical groups of hydrophones, three water pressure sensors and a bottom seismic pickup. An earthquake signal is detected at the seismic station. The epicentre region and the magnitude of the earthquake are determined. Hydroacoustic signals generated by the earthquake are received by the hydrophones lying underwater. Tsunami information is transmitted over the radio channel. Also, underwater earthquake signals are detected by the distributed system of bottom seismic pickups. The distributed system of hydrophones is switched to a time-gated standby mode. Arrival signals of the hydroacoustic wave are detected by the distributed system of hydrophones. Water pressure change signals are detected at a certain calculated time interval by the spatially distributed system of water pressure sensors. Signals of the group of hydrophones and water pressure sensors and their coordinates are used to determine the azimuthal direction of the front of the water wave and the tsunami wave, energy parameters of the tsunami wave, the epicentre of the tsunami wave and time characteristics associated with the prediction of the movement of the tsunami wave.

EFFECT: high reliability of predicting a tsunami and determining epicentre thereof.
