Any natural process, phenomenon, or human activity that has the potential to cause loss of life, injury, property damage, social and economic disruption, or environmental degradation. Hazards can originate from geological, hydro-meteorological, or biological sources, as well as from human actions such as environmental degradation or technological failures. They may manifest as immediate events or latent conditions that could trigger future incidents. Characteristics include magnitude, intensity, speed of onset, duration, and spatial extent. Hazards can also interact, such as floods following hurricanes or tsunamis triggered by earthquakes. Risk is often assessed by analyzing historical data or scientific models to determine the frequency and intensity of potential events across different areas.
