Surviving a Tsunami
Tsunami is a combined Japanese word, 'Tsu' meaning harbour and 'nami' which means wave. So the word literally means harbour wave.
A Tsunami is the result of an upheaval on the sea floor which has caused the sea to swell up and create a large wave caused by water depth. When the wave approaches land and more shallow water it slows but the water column in the deeper water is moving faster and catches up resulting in a massive wave much higher. A tsunami can be more than one wave so just because one has occurred does not mean it is the last.
According to a government report, "When a tsunami travels over a long and gradual slope, it allows time for the tsunami to grow in wave height. This is called shoaling and typically occurs in shallow water less than 100m. Successive peaks can be anywhere from five to 90 minutes apart. In the open ocean, even the largest tsunami are relatively small with wave heights of less than one metre. The shoaling effect can increase this wave height to a degree such that the tsunami could potentially reach an onshore height of up to 30 metres above sea level. However, depending on the nature of the tsunami and the near shore surroundings, the tsunami may create only barely noticeable ripples."
Tsunami can build up speeds of 950km/h or over 500 miles per hour in deep water. And this can is similar to the speed of a jumbo jet.
A Tsunami starts of as a ripple and grows bigger and bigger until they are a gigantic wave when they hit the shore. They can be as high as 30 meters or 100 feet and at that speed are devastating to anything on land.
So if you live close to the sea or even within 100 miles of it it is important to be able to read the signs that a Tsunami may be on the way.
An earthquake or rumbling in the ground.
At the shore the sea pulls back as if the tide is going out suddenly.
Animals are very sensitive to such things and may behave strangely and start to flee
Various emergency services may have advanced warning through the weather bureau by the use of satellites that a Tsunami is on its way.
Leave the beach or sea front immediately as quickly as possible going inland as far as you can.
If you are at the beach or sea front or in a low lying area, leave immediately and as far away as possible and to higher ground. If you see or hear these warning signs, don't wait for local emergency services. A Tsunami can hit within minutes of warning signs. However tune in to emergency services while you are doing the above and listen to what they have to say and follow their advice.
Go to higher ground. Go up a hill or to a higher area of your town or city. If you are trapped, find a high and strong building and climb to the top of it. You might even have to sit on its roof.
Leave possessions behind. Your life is more important than personal possessions. Leave them behind and get to safety.
Check around for young children. Even if they are not younger, you can still help them
Stay away for several hours. A tsunami can continue to hit the shore for many hours, so the danger may not be over for a while. Do not return to the area until you get an "all clear" message from emergency services. If you do not get this message, wait patiently.
Find a radio. If somebody has a radio where you are sheltering, listen to it for updates.
It is a good idea to have a safety pack. Food, water, and a first aid kit are among the basics required. Keep the safety pack somewhere obvious, well-known to everyone in the building and easy to grab in an emergency. It can also help to leave a raincoat or other coat for each person near the safety pack.
Make a personal survival pack for each person in the family, and a family survival pack with common items for everyone. Include a supply of necessary medications for each member of the family and don't forget survival items for your pets also.
When it comes to surviving a Tsunami, speed is of the essence. Knowing what to do at the time and doing it fast can save lives.
