there will be a slow decrease in the volcanic activity.
Information on the development of the activity refers on the one hand to the subsidence of the Bardarbunga
caldera and on the other hand on the intensity of the volcanic eruption in Holuhraun.

Conclusions (postmodern science)
• We have developed a large number of tools, methods, and approaches
• We have very little knowledge of the actual impact of scientific work.
In terms of scenarios, we need to focus research on the scenario
quality indicators, particularly
o Legitimacy (do justice to a wide range of ideas and perspectives)
o Credibility (recognisable from
