Document Summary
Hazards = threat: consider in human context, non- and natural. Risk assessment: exposure to dancers, adverse or undesirable prospects and the conditions that contribute to danger. Disaster and catastrophe: hazards are predictable from scientific evaluation. Start as natural processes, as part of the system. Should we control or accept: risk analysis is an important component in our understanding of the effects of hazardous processes. Risk a product of the probability of an event times the consequences should it occur. Consequences damage to people, property, economic activity, public service. Barrier lack of data on probability and consequence: linkages exist between different hazards as well as between hazards and the physical environment. Natural hazards are often linked i. e. hurricane and flooding; earthquakes and landslides; volcanoes and tsunami. Hazards linked to earth materials i. e. shale or clay and landslides; granites and blockslides: hazardous events that previously produced disasters are now producing catastrophes.
