Modelling Of Relationship Between Natural and Man-Made Hazards

Abstract

Natural hazards are known to be as old as nature but man-made hazard are of recent origin. Beginning with the industrial era man’s activities started to cause considerable changes in the natural environment. Presently they have reached such a high level that their physical, chemical or biological effects become sometimes similar to the effects of natural hazards and even to the natural phenomena causing disasters. Some attempts were made by the author to research the influence of man’s activities on natural phenomena causing disasters.

On the other hand, some natural phenomena, although not necessarily powerful enough to cause natural disasters, can give hazardous character to man-made activities or can give disastrous character to man-made hazards. This is the reason why natural and man-made hazards deserve not separate, but coupled studies. Until now they were mainly analysed and studied selectively and separately.
