Page 4 - EARTHQUAKE ITS EFFECTS AND TSUNAMI

Tsunami

• A tsunami is a huge sea wave.

• A tsunami happens when there is an earthquake or a volcanic

eruption under the sea.

• The energy from the earthquake transfers to the sea to make

huge waves. Sea waves increase in height when they reach

shallow water.

• So when a tsunami reaches a shallow coastal area, the area

along the border between the land and the sea, the wave can

reach a height of 50 metres.

• This huge wave causes flooding of coastal areas.
