Tsunami

How does Tsunamis Happen
WALA: How Tsunamis happen

Tsunamis are formed by Earthquakes, Landslides and Volcanic eruptions. It Is one of the most powerful Natural Disaster that can bring death to anyone, at anyplace and anytime.

Tsunamis are formed by Earthquakes that is generated in the subduction zone. This means when the two tectonic plates meet, and one of the plates go under the Earth’s mantle it is creating a Earthquake. For example, put your hands together but imagine them as the Earth’s crust, the line between your hands is the fault line and when you put one hand up, the tectonic plates are sliding against each other which is creating a Earthquake. The effect of this occurring in the ocean that will create a Tsunami.

An imported part of a Tsunami happening, is only when a specific Natural Disaster occurs. That means if a Earthquake, Landslide or a Volcanic eruption there is a possible chance of their being a Tsunami.Landslides can only make a Tsunami when the Landslide is moving rapidly and the mass of the Landslide goes into the ocean/water. Because the Landslide is moving rapidly so once it does go in the ocean it’s still moving rapidly, which is creating series of waves, that is forming a Tsunami. But if this did happen it would make a Tsunami but it also would Damage peoples cars and others, when it goes down to the ocean.

Tsunamis are very dangerous, they can wipe out villages in the matter of minutes. Tsunamis mostly happen in the Pacific Ocean because, their are many Earthquakes and others Natural Disasters that create a Tsunami. For example, because of the subduction zone along the ring of fire, ninety percent of Earthquakes occur on the ring of fire, and the ring or fire is the Pacific ocean basin which is mostly known as the ring of fire. Well hopely one of those Natural Disasters doesn’t happen or else our homes and our belonging will be destroyed.

Tsunamis are formed by Earthquakes which is generated in the subduction zone. Tsunamis mostly happened in the Pacific Ocean, but because of all the Earthquakes, Landslides and Volcanic Eruptions in the Pacific islands, it is  more lucky for a Tsunami to occur on one of those islands.
