Man-made hazards provoke higher levels of concern compared to natural hazards
Risk assessment in man-made disasters is predominately based on the perception of dread and causalities (Brun, 1992). Furthermore, it has been shown that man-made hazards (such as nuclear accidents) tend to be rated as very high on both dread and the unknown factor, hence they produce a higher level of concern compared to natural hazards (Peters & Slovic, 1996).
