Disasters can occur as a consequence of the impact of a natural or a human caused hazard. This study aims to analyze the multiple hazards of Thiruvananthapuram district. The disasters considered for the study are flood, forest fire, coastal erosion and drought. Separate methodology is developed for each of these disasters to analyze the severity of hazard. The results obtained from the study reveals that Thiruvananthapuram district is prone to flood, drought, coastal erosion and forest fire. The integration of individual disaster maps created the multi hazard map of the study area. It indicates some of the regions in study area prone to multiple hazards. By using these databases a risk information system for disaster management in Thiruvananthapuram district was developed. The web based disaster management systems can reduce the pressure of organizers to manage information and data directly after a disaster and in the midst of a time of crisis.
