Abstract. We live in a complex and highly dynamic risk society, and given the massive environmental changes, exposure to hazards has become a critical concept that is part of all risk assessments made from a spatial perspective. In urban studies, evaluating exposure to different risk phenomena influences targeted policies and planning that can shape cities while making them safer. As in other post-socialist countries, in Romania, cities have had a highly divergent recent evolution, including processes such as urban shrinkage, the suburban advancement of cities, and urban sprawl. Focusing on seven cities from the North-East Region of Romania, the current paper is an exploratory study regarding the dynamics of exposure to landslides in relation to suburban advancement and densification of cities. Using the official statistics, available GIS databases and information based on satellite images illustrating urban land use changes in the last 20 years, the paper includes a general overview of the overall evolution of urban areas against landslide probability, followed by a more in-depth assessment of specific areas that were subject to functional change and currently include buildings that are susceptible to be affected by landslides. The results and conclusions converge towards the idea that the identified exposed areas, where actual ground movements are currently registered, need special attention from experts and authorities to identify and manage risks. The significance of our findings is underscored by their potential to inform and guide more effective territorial management and urban land use planning strategies.
