The Iranian plateau is located in a very seismically active region of the world and is known not only for its major catastrophic earthquakes but also for the disasters relating to natural hazards, especially earthquakes.

About 2 percent of the earthquakes in the world occur in Iran, but more than 6 percent of the victims of the world’s earthquakes during the 20th century are reported from Iranian earthquakes.
