STATEMENT

Background Our earth is structured by different layers and they are still unstable. It means our earth’s layers moving everyday without our notice. So there are some strong layer movements caused by that unstableness. It makes layers slide and collide in order to make what we call EARTHQUAKE.

Target Audience All of us, who have been worrying and curious why earthquake often happens on our earth.

Objectives Explan by visual diagram to let target audience know earth’s structure and the reason why those structures influence to earthquake phenomenon.

Obstacles Details in earthquake steps.

Key Benefit . understand more about earthquake . experience in working with visual diagram

Reason Why There are lot of details to explan how earthquakes works. Moreover, must understand somethings in Physic and Geometric that related to earth’s structure.

Tone Kind of heavy. Earth tone.

Media Print. Web: Youtube, Facebook. News. Creative Considerations More details - More Earthquake’s place

Because of 2nd and 3rd stage,2 Continetial Crust layers seperated by Ocean Crust collides each other.This causes shock or earthquake at the red point.

1st stage.At this point, Ocean Crust got broken.

Lithosphere layer slides up.It pushes above layer (Continential Crust) slides to left side.
