Question

What is Tsunami? Describe the main causes of Tsunami.

Answer 1

A situation of abrupt very high tides in the oceans, which is caused either by earthquakes and/or volcano is called Tsunami.Earthquakes, eruption from a volcano cause a sudden disturbance in the base of the ocean causing abrupt displacement of oceanic waves.
Normally only one high wave is produced and in due course chain of waves appear on the sea. The speed of the waves is slow in shallow sea and is high in deep sea. In the deep sea, length of the Tsunami waves is more and the height in less. On the shallow shores the waves can be 15 metres high or even more. This results into great disaster on the coastal area.
