•   There is an enemy beneath our feet.
•  He recognizes no national boundaries, no political parties.
•  everyone in the world is threatened by him.
•  The enemy is the Earthquake. 
• The power of a quake is greater than anything man himself can produce. 
• But today scientist are diverting more of the efforts to finding some way to combat earthquakes and it is possible that are sometime in future mankind will have discovered a means of protecting itself from it. 
• An earthquake strikes without warming. 
• When it does, its power is immense.
•  If it strikes a modern city, it can take down buildings and cause death and injury.
•  If the quake strikes the sea, huge tidal waves sweep inland. 
• If the strikes in mountain regions, avalanches roar down the valleys. 
• there are three regions in the world where earthquakes are most likely to happen.
•  scientist call them as a earthquake's zones.
•  the first runs along the east coast of the Asia continent and the second runs along the west coast of south America.
•  The third runs across the south of Europe and north Africa. 
• If you take the map of the world and mark on it the locations of all the major earthquakes in history, you will see that they have occurred somewhere in these zones. 
• so it is possible for scientists to say where earthquakes will strike, but they cannot say exactly when.
