Abstract:
Tsunamis are water waves generated by a sudden vertical displacement of the water surface. They are waves generated in the ocean by the disturbance associated with seismic activity, under sea volcanic eruptions, submarine landslides, nuclear explosion or meteorite impacts with the ocean. These waves are generated in the ocean and travel into coastal bays, gulfs, estuaries and rivers. These waves travel as gravity waves with a velocity dependent on water depth. The term tsunami is Japanese and means harbour (tsu) and wave (nami). It has been named so because such waves often develop resonant phenomena in harbours after offshore earthquakes.

Kerala is one of the smallest states in India which is situated in the south west coast of the
country. Sediment samples from four prominent areas of Kerala Coast were collected and
analyzed for nutrients. Variation of nutrients was highlighted according to the distributional
characteristics of the designated sites. Nutrient trend in Cape, Trivandrum, Kollam was in the
order as Ammonia > Nitrite >Nitrate, where as Cochin showed the trend as Ammonia >
Nitrate > Nitrite. Greater concentration of ammonia in the entire sediments showed the
ammonification of nitrogen compounds
