Dropping A Little Bit Knowledge

From My Understanding a Natural Hazard is something whether it is things like weather or different climates that have the potential to injury ether property and/ or life. Disaster I like to look at it as the next step above a natural hazard. It has some requirements like number of deaths that occurred and number of people it has affected. And a Catastrophe is the next step about that and two steps above a Natural Hazard. This would be like Hurricane Katrina. A state of emergency is a must and unlike the others, This takes years possibly decades to overcome.
