Despite the alleged mastery of humans over nature, contemporary societies are acutely vulnerable to natural hazards. In interaction with vulnerable communities, these transform into catastrophes. In a deep historical perspective, human communities of many different kinds have been affected by numerous kinds of natural disasters that may provide useful data for scenario-based risk reduction measures vis-Ă -vis future calamities. The low frequency of high magnitude hazards necessitates a deep time perspective for understanding both the natural and human dimensions of such events in an evidence-based manner. This paper focusses on the eruption of the Laacher See volcano in western Germany about 13,000 years ago as an example of such a rare, but potentially highly devastating event. It merges Lee Clarke's sociological argument for also thinking about such very rare events in disaster planning and David Staley's notion of thinking historically about the future in order to 'past-forward' such information on past constellations of vulnerability and resilience. 'Past-forwarding' is here intended to signal the use of such deep historical information in concerns for contemporary and future resilience. This paper outlines two pathways for making archaeological information on past extreme environmental events relevant in disaster risk reduction: First, the combination of information from the geosciences and the humanities holds the potential to transform ancient hazards from matters of fact to matters of concern and, hence, to more effectively raise awareness of the issues concerned. Second, in addition to information on past calamities feeding into preparatory scenarios, I argue that the well-established outreach channels available to the humanities (museums, in particular) provide powerful platforms for communication to multiple publics.
