OPEN OCEAN TSUNAMI WAVE INDICATOR-SIGNALLING DEVICE Russian patent published in 2015 - IPC B63B22/00 G01V99/00 

FIELD: physics, signalling.

SUBSTANCE: invention relates to water craft and can be used to detect tsunami waves on the open ocean. The apparatus includes a platform (1) fitted with a buoy (11). The platform (1) is provided with a buoyancy function and the capacity to maintain a given underwater horizon through vessels (2) connected to the platform and by hoses (3, 4) to a cylinder (5) with compressed gas and a water pump (6). The platform (1) is fitted with a pressure sensor (7) (i.e. tsunami sensor), a control unit (8), a power supply unit (9) and a unit (10) for processing signals from the pressure sensor (7). The buoy (11) is linked to the platform by a cable-coupler (15). The buoy (11) is provided with a self-contained immersion and emersion system (12), a navigation signal receiver (13) and a transmitter (14) for transmitting information via a satellite channel.

EFFECT: faster notification of a tsunami wave owing to the proximity of the measurement equipment to the forecast earthquake source.
