The difference between natural and man-made disasters is the element of human intent or negligence that leads to human suffering and environmental damage; many mirror natural disasters, yet man has a direct hand in their occurrence.
These are the net result of inadequately managed man-made hazards and they typically cost the most in terms of human suffering, loss of life and long-term damage to a country's economy and productive capacity.
Less common man-made disasters are aviation accidents such as the 1937 Hindenberg accident and structural accidents such as the 1981 collapse of two of the three concrete walkways at the Hyatt Regency Hotel in Atlanta.
Below are links to facts about the most common man-made disasters.
