Earthquake damage depends on several factors: 

 -Intensity and duration of the vibrations 

 -Nature of the material on which the structure is built 

 -Location 

 -Magnitude 

 -The distance the earthquake is from the Epicenter (the Epicenter   is the point on the Earth's surface directly above the focus of an earthquake.)

 -Local geologic conditions 

 -Secondary effects 

 -Population density 

 -The accessibility of communication systems 

 -The time of day and the time of year
