mitigation rather than curative measures

mitigation rather than curative measures can be of great help in monitoring the movement of tectonic plates. (ii) Preparing a vulnerability map of the vulnerability risk information among the ways and means minimising the adverse impacts of disasters. (iii) Modifying the house types and building- buildings, large industrial establishments and big urban centres in such areas. (iv) Finally, making it mandatory to adopt light materials in major construction activities in the vulnerable areas.

cause the sea-floor to move abruptly resulting in sudden displacement of ocean water in the form of high vertical waves are called tsunamis (harbour waves) or seismic sea waves. Normally, the seismic waves cause only one instantaneous vertical wave; but, after the initial disturbance, a series of afterwaves are created in the water that oscillate between high crest and low trough in order to restore the water level. upon the depth of water. It is more in the shallow water than in the ocean deep.

As a result of this, the impact of tsunami is less over the ocean and more near the coast where they cause large-scale devastations. Therefore, a ship at sea is not much affected by tsunami and it is difficult to detect a tsunami in the
