What are the effects of earthquakes?

You may be wondering why do some earthquakes cause more death and damage than others? The effects of earthquakes vary from place to place. The impact of an earthquake depends on a variety of factors such as how strong the earthquake is, the size and density of population in the area affected by the earthquake (how crowded the area is), the time of day the earthquake strikes and the level of economic development (how rich or poor) of the area struck.
