No "strong" is not an appropriate adjective to describe a tsunami.
If you mean how then here it is because the earthquake might of happened in the sea and went to japan and then the earthquake was strong enough to make a tsunami
It got destroyed because the force or pressure of the tsunami was too strong.
The tsunami doesn't have a rating of strength like the earthquakes do but their were 20 to maybe30 foot waves racing in and through Japan
Japan it gets very strong earthquakes and may cause a tsunami
Anyone can; even people continents away can be affected by really strong earthquakes. Japan had an earthquake and a tsunami that caused a tsunami in Hawaii.
The tsunami hit Japan's northeastern islands.
Japan!
It's not likely for tsunami's to continue hitting Japan.
