Question

How does the shape of the seabed affect the way the tsunami impacts the coast (like in Sumatra)​

Answer 1

Explanation:

As a tsunami leaves the deep water of the open ocean and travels into the shallower water near the coast, it transforms and travels at a speed that is related to the water depth and hence as the water depth decreases, the tsunami slows down. As a tsunami approaches shore or land it begins to slow and grow in height.In the coastal areas, a tsunami may appear as huge wall of water coming towards the coast. With its tremendous energy, the fast moving waves can crush houses and other structures in the coastal areas. Most of the deaths caused by a tsunami are due to drowning.
