What is a tsunami?
A tsunami (pronounced as Soo-NAH-mee) is a series of traveling ocean waves which is usually triggered by an underwater earthquake. Such violent movement of the Earth's tectonic plates can displace an enormous amount of water and send powerful shock waves in every direction, and cause flash floods.
In 2004, a great tsunami swept through a dozen countries and killed more than 200,000 people following a magnitude 9 earthquake off the coast of Sumatra in Indonesia on December 26.
What should be done in the event of a tsunami warning?
• Make your family informed if there is a tsunami warning. Evacuate your house if you live within a tsunami evacuation zone. Keep calm, and be on standby for advisories from your local law enforcement authorities.
• If you live within or near the beach, or low-lying coastal areas, move immediately to higher ground even before a tsunami warning is issued. Keep away from bodies of water immediately.
• Homes and small buildings located in low lying coastal areas are not designed to withstand tsunami impacts. Do not stay in these structures should there be a tsunami warning.
