Tips For Tsunami Emergency Preparation
Tsunami: What to Do and How to Survive
Tsunamis used to be the stuff of movies and until it's devastation in
Asia, most people didnít 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.
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.
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
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
You might want to secure your house, but remember that this is the last
priority. Your life and that of your family's are the most important
considerations during a tsunami emergency. Expect items in your house
to be swept away and if you could still secure them, do so.
Tsunami watch vs. tsunami warning
A tsunami watch is different from a tsunami warning. A tsunami watch
means that the presence of a dangerous tsunami is not yet confirmed or
verified, although it is possible there is one. It also includes
predictions on what time the tsunami is expected and where it will
A tsunami warning means that there is a confirmed tsunami in your area
and it could be close. The warning will include the time at which the
tsunami is expected and which areas are affected.
As a last emergency tipÖ
If you find yourself under the mercy of an incoming wave, climb onto
the rooftop of your house or on the highest point of the nearest
structure and brace yourself. Hold on tightly to anything that's strong
and stable enough. Climb a tree if you have to and donít let go.
If you're already in the water, grab a floating object that can hold
your weight and hold onto it until you can reach stable ground or when
help is available. Grab onto anything that is firm and strive to get
out of the water as much as possible. The current will be strong and
there could be heavy and sharp debris in the water that could crash
Tsunamis, like most things nature produces, are uncontrollable. The
only advantage is that they do come with a warning (a strong
earthquake). The only way to survive it is to be prepared, be ready to
go and to keep your wits about you.
