Disaster history refers to the study of significant events that have caused widespread destruction and loss of life throughout time. This includes natural disasters like earthquakes, floods, and hurricanes, as well as human-made disasters such as industrial accidents and wars. Understanding these events helps societies learn from past mistakes and improve disaster preparedness. Researchers analyze historical records, survivor accounts, and scientific data to understand the causes and impacts of disasters. This knowledge is crucial for developing better response strategies and policies. Notable examples include the 1918 influenza pandemic, the Hurricane Katrina disaster in 2005, and the Chernobyl nuclear accident in 1986.
