**General Framework** Climate change in cities affect differentially depending of multiples combination of social, economic and environmental parameters, which are in turn dependant on the degree of exposition, sensibility and adaptation capacity of the urban territories. Generally, adaptation plans and actions are most effective when they are performed at the local level, with a keen understanding of how risks interact with different areas and populations within human settlements. Multiparameter and criteria methodologies are used to combine parameters to create high resolution climate risks analyses, to be able to visualizing patterns and distributions of exposure, sensitivity and response capacity in the territory, were the risk overlap and the interaction of this parameters is a fundamental analytical challenge. This study illustrates the application of a spatialized fuzzy-set methodology to map climate risks in the Viña del Mar-Valparaiso conurbation, a coastal city in central Chile. Previous studies have shown that fuzzy-set techniques are particularly useful for climate risk assessment because they are able to combine quantitative and qualitative indicators of heterogeneous nature, source and scale in a comprehensive narrative on risk, one which is more immediately understandable and accessible to decision-makers and practitioners in charge of urban adaptation planning. The conceptualization of risk follows the 5th Assessment Report from Working Group II of the IPCC. On this basis, it employs a variegate set of climate, geographical, socio-economic, demographic, infrastructural and administrative data to tackle climate risks associated to heat waves, drought, landslides, fires, flooding and extreme tidal phenomena on the population, their dwelling, and key urban services. The results allow to identify the influence and impact of climate hazards or combination of hazards on the territory at a resolution unprecedented in the country, considering this amount of information. Large proportion of the analysed territories exhibit high levels of exposure to multiple hazards, while other areas only affected by one or two of them. The suburban perimeter, mostly built on hills and gorges, is found to be the most vulnerable part of the conurbation across all threats. This occurs due to a combination of geographical factors (the presence of high slopes, exposure of hillside, type of ground cover, and others), a reduced coverage of emergency services and overall response capacity, and the generally higher socio-economic and socio-demographic vulnerability of the population residing in those zones -both because of socioeconomic inequalities and of spatial patterns related to informal settlements, access to infrastructure and urban services.. The microzonification of the climate risk in these two important Chilean cities provided by this study provides key information for climate change adaptation and a model for the next urban plans in the country. Final reflections are provided on the need of further work on the conceptualization and analysis of how different hazards interact and compound one another, a necessary step to advance toward an integrated assessment to climate risk. **Acknowledgments** ARClim project, which include several Chilean academic unities, sponsored by the country's environmental ministry and the German GIZ.
