What is an earthquake?

Earthquakes are the shaking, rolling or sudden shock of the earth’s surface.

They are the Earth's natural means of releasing stress.

Earthquakes can be felt over large areas although they usually last less than one minute.

Earthquakes cannot be predicted, although scientists are working on it.

Three layers of earth…

The inside of earth is made up of 3 main layers of earth known as:

1)Core: The innermost part of the earth is known as core

2)Mantle: The central region of the earth between the core and crust.

3)Crust: The outermost layer of earth is called crust.

Focus and Epicenter

Why do they occur?Earthquakes occur when the moving plates of the earth’s crust :

Slide past one another

Collide with one another

EFFECTS OF EARTHQUAKE

Loss of life and Property

Ground shaking

Fire

Tsunami

Landslides

Sometimes rivers change the course

ADVANTAGE OF EARTHQUAKE

Knowledge about earths interior

Formation of soils

New landforms

Natural lakes are formed

ADVANTAGE OF EARTHQUAKE

Without earthquake in the world, the size of the

energy which is generated by the magma would

increase.

Thermal water resources, mineral resources, water

resources, such as healing waters, actually happens

the result of an eartquake.
