that experienced a period of time . Eartquake is measured by “Richter magnitude
scale” .Earthquake may be caused naturally or by human deeds . Rupture of
geological faults is the most common cause of this disaster. Earthquakes
manifest themselves by shaking at the surface of the earth & sometimes displacement of the ground may
occur. The point of initial rupture of earthquake is called its focus or hypocenter
. The ground level directly above the hypocenter is the point that called
epicenter .Tsunami can take place when the epicenter of a large earthquake is
located offshore and the seabed is sufficiently displaced. Landslides and
volcanic activity may result after major earthquake. Earthquake can be so
violent that toss people around & destroy whole cities . It is so alarming
that earthquake is occurring everyday on any part of the world in the recent
