The research project aims to address critical gaps in existing studies related to disaster risk assessment by adopting a comprehensive, multi-hazard approach in the context of Chittagong city, Bangladesh. Leveraging a quantitative research strategy, the project integrates hazard exposure, vulnerability, and socio-economic factors to develop a nuanced understanding of multi-hazard risks. Chittagong's dynamic physical and geological characteristics make it susceptible to a range of hazards, from frequent landslides to infrequent but high-magnitude events like cyclones and tornadoes. Utilizing a diverse set of spatial and social data from reputable sources such as IBTrACS, GeoDASH, LGED, FAO, USGS, NOAA, CDA, and Bangladesh's Population and Housing Census, the project employs Analytical Hierarchical Approach (AHP), Multi-Criteria Decision Making (MCDM), and Geographic Information System (GIS)-based methods for data analysis. By doing so, the research intends to establish the nexus between hazard, exposure, and vulnerability, mapping the multi-hazard exposure and vulnerability of the study area. The project goes beyond traditional assessments by normalizing data, categorizing risk, and creating hazard intensity scales. This detailed approach allows for the identification of risky areas and facilitates emergency evacuation planning. The anticipated outcomes include not only comprehensive maps of multi-hazard exposure and risk but also policy guidelines for risk mitigation and disaster reduction. The research's broader implications extend to providing decision-makers, planners, NGOs, communities, and stakeholders with actionable insights for resilience-building and vulnerability reduction. By addressing the lack of individual hazard intensity scales and emphasizing a larger-scale multi-hazard risk map, this research contributes to a detailed, practical, and policy-oriented guide for multi- hazard risk assessment procedures in Bangladesh.
