Acehtsunami

Tsunami (pronounced soo-NAH-mee) is a Japanese word. Tsunamis are quite common in Japan and many thousands of Japanese have been killed by them in latest centuries.
• An earthquake generates a tsunami if it is of adequate force and there is violent movement of the earth causing substantial and sudden displacement of a huge amount of water.

• A tsunami is not a single wave but a sequence of waves, also known as a wave train. The first wave in a tsunami is not necessarily the most destructive. Tsunamis are not tidal waves.
• Tsunami waves can be very long (as much as 60 miles, or 100 kilometers) and be as far as one hour apart. They are able to cross entire oceans without great loss of energy. The Indian Ocean tsunami moved as much as 3,000 miles (nearly 5,000 kilometers) to Africa, arriving with sufficient force to kill people and destroy property.
