Problems of Increasing Natural Hazards in the Global Scale
It is obvious that there is a remarkable trend of increasing in the global surface temperature. The increase of the global surface temperature is meteorologically predicted to drastically cause various disasters such as sea level rise, storm and flood damages. The number of storm and flood disasters with more than 100 people missing in the world has drastically increased from 1986, where the majority of the eases occurred in Asia. Besides, the number of large earthquake disasters seems to be increasing in recent yeats. The increasing trend in the extent of damages by natural hazards is attributed not only to the global climate changes but also to the fragile structure of the recent social systems. The excessive degree of urbanization to concentrate population in limited areas accelerates the danger of victims of the natural hazard. At the same time, tremendous amount of energy is consumed as well as accumulated in the public utility such as power plants or high speed transportation system or in the industrial sectors such as petroleum or chemical plants that could be the cause of disaster once such energy is released by the damage. In the present paper, the problems of natural hazards causing serious damages all over the world are overviewed and, in addition, some typical examples of the hazard caused by big earthquakes encountered in Japan are reported including the damages at the nuclear power plant caused by the Chuetsu earthquake.
