Tsunamis
By - Blake in Grade 7
Tsunamis are huge waves caused by land splitting under water. The meaning of Tsunami in Japanese is “Harbor Wave”. How fast a normal Tsunami is about 500 mph.
Ways That Tsunamis Can Start
1 - When the sea floor cracks and then one half of the floor with drop, then water will go into the void then back up as a Tsunami.
2 -
If a landslide is big enough it will make a Tsunami.
Under water volcanos also start Tsunamis from erupting.
