Disaster
Event or chain of events resulting in major damage, destruction or death / From Wikipedia, the free encyclopedia
Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about Disaster?
Summarize this article for a 10 year old
A disaster is an event that causes serious harm to people, buildings, economies, or the environment, and the affected community cannot handle it alone.[1][2] Natural disasters like avalanches, floods, earthquakes, and wildfires are caused by natural hazards.[3] Human-made disasters like oil spills, terrorist attacks and power outages are caused by people. Nowadays, it is hard to separate natural and human-made disasters because human actions can make natural disasters worse.[4][5][6] Climate change also affects how often disasters due to extreme weather hazards happen.

Disasters usually hit people in developing countries harder than people in wealthy countries. Over 95% of deaths from disasters happen in low-income countries, and those countries lose a lot more money compared to richer countries. For example, the damage from natural disasters is 20 times greater in developing countries than in industrialized countries.[7][8] This is because low-income countries often do not have well-built buildings or good plans to handle emergencies.
To reduce the damage from disasters, it is important to be prepared and have fit for purpose infrastructure. Disaster risk reduction (DRR) aims to make communities stronger and better prepared to handle disasters. It focuses on actions to reduce risk before a disaster occurs, rather than on response and recovery after the event. DRR and climate change adaptation measures are similar in that they aim to reduce vulnerability of people and places to natural hazards.
When a disaster happens, the response includes actions like warning and evacuating people, rescuing those in danger, and quickly providing food, shelter, and medical care. The goal is to save lives and help people recover as quickly as possible. In some cases, national or international help may be needed to support recovery. This can happen, for example, through the work of humanitarian organisations.
