Why is it difficult to avoid a tsunami?
Gelneren [198K]

Answer:

It is difficult to avoid a tsunami due to it being such a large volume of water that is capable of destroying a large amount of land.

Explanation:

However, even though it is difficult to avoid a tsunami, as they are extremely difficult to predict, there are ways where one can begin to prepare before it hits. One of the ways you can do this is getting to a higher ground far away from inland, avoiding downed power lines, and steering clear of buildings or bridges where large, heavy objects could fall during an aftershock.

Tsunamis are incredibly dangerous, since there is a great chance that if you get caught in one, you can drown. Since tsunamis have little to no warning when they arrive, it is always essential to be prepared when one strikes.

I hope this helped! :)
