INTRODUCTION

Some people say tsunamis are

tidal waves. Tsunami comes from two

Japanese words, (TSU) means harbor

and (NAMI) means wave. So tsunami

means harbor wave.

HOW IS TSUNAMI FORMED

Waves are formed differently than tsunamis because, when the

wind blows the water it only affects the upper layer. But tsunamis

are formed deep under water, so if it affects the bottom layer, all

of the layer is effected. Tsunami is mostly affected by earthquakes

or under water earthquakes, but some times landslides and volcanic

eruptions can also cause deadly tsunamis. The under water earth

quake in the subduction zones are most common. When an oceanic

plate hits a

continental plate,

eventually the

heavy oceanic

plate, pushes and

goes under the

continental plate.

The earthquake lifts the part of the ocean floor up and parts down,

what happens with the ocean floor is mirrored with the water

surface. But gravity evens out the water surface. Even though you

think the water surface is flat, but actually under the water, they

are really fast waves. Tsunami extends 16 thousand km long! When

the tsunami arrivers to the shore they don’t have enough space to

go, so they slow down and pack together. The water swells and

forms a wall of water with a whole lot of energy inside. The

water force can break houses. The 2004 Boxing Day tsunami, at

the Indian Ocean, the earth quake magnitude was 9.0. Tsunamis
