ABSTRACT
Traditionally, tsunami detection has completely depended on a coastal tide gauge network. In recent years pressure sensors at the ocean bottom in the Pacific have been providing some additional valuable data in real time. Some other possible detection methods of the tsunamigenic earthquake and tsunami signals in the troposphere, as well as in the ionosphere are also being considered. The observation that certain animals are able to detect and react to earthquake and tsunami signals, is gaining some credibility in recent times. If this ability of animals could be exploited, it will provide some additional guidance in real-time tsunami prediction.
