The 8.2 ka event had a major but regionally variable climatic impact in the Northern Hemisphere. In Denmark, it impacted lakes and rivers, which were essential landscape features for contemporaneous foragers. There is also evidence for a marked increase in sand drift in the region. Around the same time as the 8.2 ka event, the Storegga tsunami affected the North Sea Basin. While there is considerable debate about the loss of lives and livelihoods associated with this event, we here explore whether the combination and convergence of these event-like environmental changes lead to changing land use amongst contemporaneous Maglemosian foragers in western Denmark. Placed in a theoretical framework derived from disaster risk reduction research, we focus on sites in a small part of River Gudenå catchment but also draw on regional-scale proxies of population processes. In combining these lines of evidence, we explore the possibility of a reorientation from inland to coast and from networks reaching westwards towards networks with an eastern orientation. The time of the 8.2 ka event broadly coincides with the transition from the Early Mesolithic Maglemose culture to the Middle Mesolithic Kongemose culture, raising the question of whether the environmental upheavals around this time are causally implicated.
