What is definition of cataclysms?

Cataclysms are a series of violent natural events that cause massive changes in the world around us. They may be caused by geological, meteorological, or astronomical factors, and can have far-reaching consequences for the Earth's ecosystems and human populations. Cataclysms can take many forms, including earthquakes, volcanic eruptions, tsunamis, hurricanes, tornadoes, floods, wildfires, and pandemics. These events can be devastating for the environment and the people living in it, leading to displacement, loss of life, and social and economic disruption. However, over time, cataclysms can also have a regenerative effect, leading to new growth and recovery in affected areas.
