What are cataclysmic events?

Cataclysmic events are sudden and often violent occurrences that result in significant disruption or destruction, typically affecting large areas or populations. These events can be natural, such as earthquakes, volcanic eruptions, and tsunamis, or human-made, like nuclear disasters and large-scale industrial accidents. They often lead to profound changes in the environment and can have lasting effects on ecosystems and human societies. The term is also used metaphorically to describe any event that brings about dramatic change or upheaval.
