Divisions of disaster

There are many different types of disasters that can occur, and they can be classified in various ways. Some common ways to categorize disasters include:

• Natural disasters: These are disasters that are caused by natural processes such as earthquakes, hurricanes, floods, and wildfires.
• Human-caused disasters: These are disasters that are caused by human actions or inactions, such as industrial accidents, oil spills, and terrorism.
• Technological disasters: These are disasters that are caused by the failure or malfunction of technological systems, such as power outages, dam failures, and transportation accidents.
• Environmental disasters: These are disasters that are caused by environmental factors such as pollution, deforestation, and climate change.
• Humanitarian disasters: These are disasters that affect a large number of people and often require the provision of humanitarian aid, such as famine and refugee crises.
