Tsunami: What to Do and How to Survive

Last year 2009 and this year 2010 tsunami always come in to our life, many country / city has been destroy and people died because of this. Tsunamis used to be the stuff of movies and until it's devastation in Asia, most people didn’t think it was possible for tsunamis to occur in that magnitude. With that realization, people have become aware of the risk and possible consequences of this natural calamity. Tsunami, what to do and how to survive :

What is a tsunami?
Tsunamis are not caused by strong winds but by tectonic displacements (earthquakes, volcano eruptions, landslides) that occur on the seafloor. Earthquakes that produce tsunamis are those that reach 6.5 or more on the Richter scale. The average speed of the waves is 300 mph and can last from 5 minutes to an hour.

In open sea, tsunamis usually go unnoticed, having amplitudes of just 1 meter or even less. However, in some situations, waves that enter shallow water can swell to several feet and in some rare cases, rise high enough to strike coastal areas with terrible force.

Who's at risk?
People who live in coastal areas located along or near the Pacific Ocean are most prone to tsunamis. This area is most vulnerable because of seismic activity in what is called the Ring of Fire. It has also occurred in Puerto Rico, Alaska, Hawaii and the Virgin Islands, indonesia, srilanka and others

What to do in a tsunami emergency
When a strong earthquake is felt, leave the water immediately, get to shore and go as far away as you can from the beach, fast. If your location allows it, go to a higher ground. If the area you are in is mostly flat, go as far inland as you can. If you can spot the wave, you are too close to escape it, regardless of its apparent distance.

Tune in to your local radio station, the weather radio or turn on the TV for news and updates. They will inform you if there is a tsunami watch or warning issued in your area and where the emergency centers are.

Locate all members of your family and make sure everyone is informed. Agree on a place to meet in case you're not together and make sure it's safe and as far away from the shore as possible.

If you have family members who have special needs like elderly people, small children or infants and those with disabilities, you might want to evacuate early. You might also want to prepare your pets for moving, so bring emergency supplies for them as well.

Check your emergency supply kits and bring them with you. It would be a good idea if they had been regularly restocked but if not, take what you can or get what is needed if you still have the time and opportunity. Otherwise, opt to get water, food and extra clothes instead.

    This article is interesting. Thank you so much for tips.
    Indonesia has experienced the tsunami disaster in Aceh some time ago. It was a horrible experience and sad. We need a high vigilance and the emergency response teams in tsunami-prone areas.
