Abstract—The Earth beneath our feet usually feels solid and firm, even though a million times each year (an average of once every 30 s) somewhere around the world, the ground shakes and sways. This is called an earthquake. Most Earthquakes are too small to be noticed by people; only sensitive scientific instruments record their passage. But hundreds of earthquakes every year are strong enough to change the face of the land and are capable of causing injuries, deaths and property damage. Seismic hazards are those associated with earthquakes. The earthquake engineering involves the identification and mitigation of seismic hazards. This paper describes behavior and damages of buildings due to earthquakes, so that several precautions in terms of earthquake resisting systems like base isolation, other energy absorbing or dissipating devices, bracings, shear walls, etc., can be developed and implemented.
