Question

what do you think maybe the cause of an earthquake ?

Answer 1

There's no warning. None at all. One minute you're happily walking down the street. The next minute the street seems to be walking all by itself! There's a deafening, rumbling, roaring noise. The buildings start to shake. Brick and glass rains down around you. A huge crack appears in the pavement. Fire hydrants burst open. Cars are crushed by falling masonry. People are screaming. It feels like the end of the world.

There's not much we can do to stop natural disasters like earthquakes: they're an inevitable part of living on a planet like Earth, seething inside with hidden power. What we can do, however, is monitor changes in the ground beneath our feet so we can predict when earthquakes will happen. We can design our buildings much more cleverly so they absorb the power of sudden shocks. And we can prepare ourselves for the inevitable by planning for the time when (and not if) the next quake will strike.

Answer 2

Cracks develop on the walls of the buildings. These cracks may lead to the collapsing of the buildings. Electric wires get snapped resulting in short circuit and fires. Breaking of dams can result can result during earthquake.
