How many catastrophic events?

The term "catastrophic events" can refer to a wide range of disasters, including natural disasters like earthquakes, hurricanes, and floods, as well as man-made incidents such as industrial accidents or terrorist attacks. The frequency and number of such events can vary significantly each year based on environmental, social, and political factors. For specific numbers, data from organizations like the United Nations or the National Oceanic and Atmospheric Administration (NOAA) would be required, as they track and report on these occurrences globally.
