What does the word tsunami mean?

Here is my finished version of what does a tsnuami mean?

The word tsunami comes from two Japanese words “tsu”, meaning harbour, and “nami”, meaning wave. Put it together and it means harbour wave. This term can be misleading because tsunamis do not always occur at harbours. Tsunamis can hit any single coastline at any single moment.

The term tsunami or harbour wave was first created by local Japanese fisherman who returned to their local port to find the area surrounding their harbour was demolished. They had been at sea the whole day and did not see or feel the tsunami passing under them. When they arrived back at the harbour all the harbour area was destroyed by the massive wave. Tsunamis are rich in Japanese history, there have been 195 recorded tsunamis.

Tsunamis are in many other ancient cultures. For example in the Indigenous Australian Aboriginal history, there is a dreamtime story which tells of a meteorite falling from the sky and made the ground shake. The following morning the land was covered by water.

In the ancient Kwenaitchechat legend, there is a story where the local people felt the ground shake and they moved towards the beach to prevent being flung into a tree or end up on their sides. The water at the beach then started to recede and a series of large waves hit. The waves destroyed all that was in its path. Then on the on the other side of the Pacific Ocean in Japan, without any warnings, large tsunami waves started coming in. This proves that a earthquake in one region can make its way across oceans as a tsunami.

There are also other real life stories from tsunamis in the last two centuries from places like Krakatau, Burin Peninsula in Newfoundland and Papua New Guinea.
