An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the earth, resulting from the sudden release of energy in the earth's lithosphere that creates seismic waves. Natural disaster impacts in general based on the statistical analysis of fatality data and introduced a set of modiﬁed and accurately deﬁned terminologies to deﬁne differ- ent severity levels. Source: health & safety executive (1989) catastrophes the most extreme hazard events create catastrophes, or disasters, which normally arrive without warning white and haas (1975) define a catastrophe as any situation in which the damages to people, property or society in general are so severe that recovery and/or rehabilitation after the event is a long and difficult process.
