Comparing Earth Disasters and Catastrophes Caused by Natural Processes

While many people use the words "disaster" and "catastrophe" synonymously, there are actually some differences between the two. The main difference between the two is that disasters occur in a defined area and over a limited time whereas catastrophes are defined by the amount of time and money it takes to repair the damage created. In order to be considered a disaster, at least one of the following must be true: 10 or more people are killed, 100 or more people are affected, international assistance is required, or a state of emergency has been declared. Disasters and catastrophes are caused by natural processes such as earthquakes, tornadoes, tsunamis, etc. These natural processes turn into hazards when humans are in their path, and these hazards can happen anywhere.
