Did you know that the word tsunami is a Japanese word🗾 that means “big wave🌊 in the harbor”? A harbor is the place where the boats are tied up.
Causes of the tsunami
A tsunami is also called a tidal wave. Most of the time, tsunamis are caused by earthquakes, by volcanic🌋 phenomena, by an underwater explosion💥, by meteorites💫, and so on.
- Origin (for example an earthquake)
- Spread (energy⚡️ that travels in water)
- Breaking on the coasts (the wave that hit the coast)
The tsunami weight and speed are problematic. The wave can go as fast as 700 to 800 km∕h, that’s🚀 really fast! The wave of a tsunami goes so fast that nobody can escape it, not even Usain Bolt🏃🏻. You need to get away very quick, there’s no time to put gas⛽️in the car. A tsunami can measure a few hundred meters high and it destroys almost everything in its path (even cars and houses). Tsunamis are natural disasters.
With scientific instruments, we can detect the cause of a tsunami and try to predict it, but it is very difficult. There are tsunami worldwide watch alert🚨 centres that can help the population👨👩👧👦 to evacuate.
In 2004, there was the biggest tsunami in the world!
- It has affected 11 countries such as Thailand
- It traveled a distance of 3000 meters in the Indian Ocean
- It killed 220,000 people😭😱
Tsunamis are very dangerous, it can happen everywhere, even in Canada🇨🇦! There was a tsunami in Newfoundland in 1929. 27 persons died during that event.
If there is a tsunami, it is necessary to flee as far as possible in the land and in elevation, on a mountain🗻 if possible. I hope the ocean is calm because I’m going to play at the beach this week.
