How To Survive A Tsunami If You Are On The Beach In The Water

how to survive a tsunami on an island

A tsunami or tidal wave, is sometimes called a seismic sea wave. It’s a series of waves in the ocean. It’s often caused by the displacement of a large volume of water. This displacement of water can be caused by an earthquake, a volcanic eruption or some underwater nuclear device that causes a major shift in water volume. A landslide, a meteorite impact, or a glacier calving, have the potential to produce a tsunami in ocean waters.

A 9.1-magnitude earthquake hit the coast of Sumatra, Indonesia. The strong earthquake released a series of gigantic waves from the Indian Ocean, which had a speed similar to that of a jet. It affected 14 different countries and claimed more or less 230,000 lives.

A tsunami can move at a speed of 600 miles per second, depending on the depth of the ocean it is coming from. The deeper the ocean, the faster the travelling speed of tsunami. Tsunamis are caused by strong disturbances such as volcanic eruptions, high-magnitude earthquakes, explosions, landslides, and meteorites.

how to protect yourself from a tsunami

Though tsunamis are inevitable and devastating, being prepared for tsunamis is one step to disaster survival. You need to know the following things especially if you live in coastal areas.

  • Areas prone to tsunamis are often low level areas. Therefore, move to higher ground. Activities such as water recession, underfoot tremors and shakes, and loud roars are usually signs which give a hint that a tsunami is coming. If you noticing these, but the authorities have yet to issue a warning, do not wait for the authorities anymore. Evacuate immediately and head toward high ground.
  • Prepare a waterproof survival kit containing water, food, medicine and clothing. People who live near the coasts must evacuate immediately.
  • Listen to news and become alert when authorities are warning of a tsunami coming. Warnings must be heeded – it’s better to be safe than sorry.

How To Protect Yourself From A Tsunami.

  • Most of the time, a tsunami is caused by earthquakes. An earthquake that lasts for as long as 10-15 minutes is usually followed by a tsunami. Duck, cover and hold while the earthquake occurs, and then evacuate. Be carefully of damaged buildings, power lines, or falling debris.
  • When the tsunami strikes, forget about your possessions, the most important thing to do is to save your life, and of others if you can. Do not think about getting possessions as this may hinder you from evacuating as fast as you can. A survival kit is more than enough.
  • Stay on high ground for a while. A tsunami is not a one-hit type of natural disaster. It is a series of tall waves. Usually, a tsunami lasts up to 3 days. To be safe, stay on high ground for at least 4-5 days.
  • Be cautious about status reports given by the authorities. Do not immediately leave the safe area — some people died due to inaccurate alerts given by the authorities.
