This paper seeks to address the variety of responses to natural risks in the Roman world. Relying on geographical concepts, it shows that the management of natural risks depended on the identification of human activities as agents of the risk. It is argued that the answers provided indicate that ancient communities were well aware that they were exposing themselves to hazards in many ways, and reflect the understanding of human enterprises and activities' impact in increasing the risk. It is also argued that this perception enabled to act upon the human components of the risk, which are more easily manageable than the natural hazard itself. This study finally makes a case for the exploitation of the legal texts in Roman history. It is shown that the legal dispositions were developed as effective tools to manage the risk at the individual level of private property, because they aim at controlling human enterprises and at reconciling competing private and public interests.
