Heatwaves are increasingly recognized as a critical climate hazard, yet vulnerability assessments have largely focused on urban areas, potentially overlooking risks in mountainous and rural regions. This study aims to evaluate the spatial heterogeneity of heatwave vulnerability in a forest-dominated rural area, using Jeongseon County, South Korea, as a case study. A vulnerability assessment framework based on the Intergovernmental Panel on Climate Changewas applied, integrating exposure, sensitivity, and adaptive capacity. Thermal exposure was represented by satellite-derived land surface temperature (LST), while sensitivity was characterized by demographic and physical indicators, including the proportion of elderly population, aged buildings, and impervious surfaces. Adaptive capacity was assessed using accessibility to cooling shelters and green spaces. All variables were standardized and combined to construct a heatwave vulnerability index (HVI). The results reveal that heatwave vulnerability in the study area is characterized by a widespread distribution of moderate vulnerability rather than isolated extreme hotspots. Thermal exposure was generally lower in forested areas but higher in settlement centers, where localized heat accumulation occurred. Sensitivity exhibited spatial differentiation, with demographic factors dominating in mountainous rural areas and built-environment characteristics playing a greater role in settlement centers. Adaptive capacity showed a spatial imbalance, with widespread access to green spaces but limited accessibility to cooling infrastructure in remote areas. These findings suggest that heatwave vulnerability in mountainous rural regions is shaped by complex interactions among environmental, socio-demographic, and infrastructural factors. Notably, areas perceived as climatically safe may still exhibit high vulnerability due to structural and spatial constraints. This study contributes by extending heatwave vulnerability assessment beyond urban contexts and by presenting a transferable framework applicable to data-scarce regions. The results highlight the need for spatially integrated and context-specific adaptation strategies that address both widespread moderate vulnerability and localized high-risk areas.
