Abstract:
Hundreds of hazards maps have been produced to show the location of volcanic hazard for at least the past 150 years. They are presented in a variety of ways and play a key role in communication of hazards at volcanoes. Not all maps, however, provide enough or the right information to make informed decisions. The published hazard map for Campi Flegrei is not effective at communicating the complex hazards and uncertainties associated with calderas volcanic activity at a local scale. Using an interdisciplinary approach, this thesis investigates four very different topics specific to hazard communication at Campi Flegrei. These include: challenging the assumptions in vent opening susceptibility studies, unrest scenario mapping, determining map user preferences, and the development of hazard maps online. By focusing on these crucial aspects, this thesis contributes in making maps more useful and usable to a variety of different audiences in this region. This study found that existing assumptions have had a large impact on how hazard areas are determined, in particular, how the choice of historical eruptions governs future estimations of vent opening probability. Analysing the results of the unrest scenarios highlighted that the impacts of unrest will vary greatly dependent on location. Also, large sections of the electricity and transportation network are exposed to seismic hazard and could be unusable during future unrest. Map preferences were identified from a survey of 245 individuals (both globally and at Campi Flegrei), concluding that whilst design preferences were generally similar, preferences for data and map types were diverse. Thus, a single map could not suit the preferences of all users. Finally, the development of a suite of new web maps for Campi Flegrei has shown how this format can be utilised and its application within volcanic hazard mapping in general.
