An earthquake is the result of a sudden release

of energy in the Earths crust that creates

seismic waves. At the Earths surface earthquakes manifest

themselves by vibration, shaking and

sometimes displacement of the ground.

The vibrations may vary in magnitude.

much more than normal.

Gamma ray burst

GAMMA RAY BURST

Gamma ray bursts are the most powerful

explosions that occur in the universe.

They release an enormous amount of energy inmilliseconds or longing for ten seconds. They

release the same energy that the sun would

have given in its whole life or even more than

that. Mostly large masses of stars, bigger than sun,

can produce a GRB.
