GIS-based Vulnerability Analysis for Disaster Preparedness Geographic Information Systems (GIS) are powerful tools for analysing vulnerability and improving disaster preparedness because they integrate geographical, environmental, demographic and infrastructure-related information in a common spatial framework. Vulnerability analysis aims to identify people, places and resources that are likely to suffer greater losses from hazards such as floods, earthquakes, cyclones, landslides, droughts and industrial accidents. GIS helps planners understand the spatial distribution of risk and supports timely decision-making. GIS can first be used to prepare hazard maps by combining information on the location, intensity and frequency of hazards. For example, flood-prone areas can be identified by integrating rainfall data, river networks, elevation, drainage patterns and historical flood records. Similarly, earthquake vulnerability can be assessed by combining seismic zones, soil conditions, building locations and _________ __________ _____ __________ ___.
