Abstract
Disclosed is a method and device suitable for detection of and warning against tsunamis. The device is located in the water at sea. The device includes a vessel, a sensor for measuring a physical quantity of the surrounding water, a control unit inside the vessel and operatively connected to the sensor, and a communication element including a transmitter for communicating with an external receiver that the predetermined condition relating to the physical quantity is fulfilled. The device further includes a ballast tank inside the vessel. The interior of the ballast tank is connected to the outside of the vessel. A pump pumps water from the ballast tank to outside the vessel. The overall density of the device exceeds the density of the surrounding water when the ballast tank is filled, and is less than the density of the surrounding water when the ballast tank is empty of water.
