Natural Disasters

With the tropical climate and unstable landforms, coupled with high population density, poverty, illiteracy and lack of adequate infrastructure, India is one of the most vulnerable developing countries to suffer very often from various Natural Disasters, viz. flood, cyclone, earthquake,forest fire, drought, etc. Asia tops the list of casualties due to natural disasters. Space technology plays a crucial role in efficient mitigation of disasters. Communication satellite provides disaster warning and relief mobilization, Earth observation satellite provides required database for predisaster preparedness programmes and post-disaster preparedness programmes. They provide comprehensive, synoptic and multi temporal coverage of large areas in real time and at frequent intervals Forest fire has deadly threatened human lives, fortune and ecosystem. The main reason for this is limitation of traditional method and no more scientific way to predict these disasters. We present that the fatal damage by forest fire could be reduced if there are suitable predictions and rapid provision against forest fire using GIS. This GIS is most perfect way for forest fire forecasting as Forest fire had a movement in both spatial and temporal. GIMS (Geographical Information and Modeling System, Kessell -1990) was installed for a management of Forest Fire, which could assign a part by telling the shape of forest fire in real time and help managers of forest fire to take best decision against these disasters. The study strategies are as follows, the investigation of actual forest fire area was first carried out and secondly constructed into GIS DB. Danger index of forest fire was computed based on topographic and meteorological factor in this area an evaluated the relationship between these factors and forest fire. GIS has created opportunities for a more detailed and rapid analysis of natural hazards. GIS database can be used to create elaborate and effective...
