GEOLOGY

Detailed explanation-1: -Technological hazards originate from technological or industrial conditions, dangerous procedures, infrastructure failure or human activity. Chemical, biological, radiological and nuclear (CBRN) hazards are all types of technological hazards.

Detailed explanation-2: -Examples of technological hazards may include industrial pollution, nuclear radiation, toxic wastes, dam failures, transportation accidents, factory explosions, fires, and chemical spills. Technological hazards also may arise directly as a result of the impacts of a natural hazard or man-made incident or event.

Detailed explanation-3: -Natural hazard events and technological accidents are separate causes of environmental impacts. Natural hazards are physical phenomena active in geological time, while technological hazards result from actions or facilities created by humans. In our time, combined natural and man-made hazards have been induced.

Detailed explanation-4: -An extreme case of destructive human intervention into an ecosystem is desertification, which, by its very definition, is a human-induced “natural” hazard.

Detailed explanation-5: -Technological hazards are normally considered a subset of man-made hazards. Chemical, nuclear and radiological hazards, as well as transport hazards are defined as those “originate from technological or industrial conditions, dangerous procedures, infrastructure failures or specific human activities.
