Tsunami damage is first caused by the immense force of the tidal wave hitting the shoreline. Tsunami flooding then continues to cause damage for several more weeks.  The effects of the tsunami on the country during this period range from destruction and damage, death, injury, millions of dollars in financial loss, and long lasting psychological problems for the inhabitants of the region.  The initial impact of the tsunami is often publicized across the world through the news media. However, the actual effects continue for many years after the natural disaster strikes.   For many of the people affected, they will never forget the terrifying ordeal of being caught in a tsunami. The scars that are inflicted on the land can be present for decades to come, and this only serves as a reminder to people living in the area of the terrible losses caused by the tsunami, and the lingering danger that yet another killer tidal wave could strike at any moment with very little warning.

Answer 2

If you are standing on the shore, and you see a big portion of water (ocean floor) moving rapidly downward ( and backwards) you'll expect the water to come back as a tsunami.
