Three unrest hazard scenario locations used in this study: (1) Pozzuoli (centred on 14.1239 longitude, 40.819 latitude), (2) Agnano (14.16447 longitude, 40.8375 latitude), and (3) Baia (14.07633 Longitude, 40.81907 latitude). Zones 1 through 4 are used in the exposure assessment and relate to the different distances from the central area of unrest. For the impact assessment, Zones 1 and 2 were grouped and used to represent areas that would experience shaking equal to a seismic intensity of VII on the Modified Mercalli Intensity (MMI) scale and a deformation of greater than 1 m. Zones 3 and 4 were also grouped and relate to seismic intensity MMI VI and ground uplift of less than 1.0 m. The zona rossa, or ‘red zone’, is the area of evacuation in the event of volcanic unrest at Campi Flegrei determined by the Department of Civil Protection (DCP 2014) and is included for comparison on these maps. This red zone includes the area exposed to pyroclastic flows, and includes the municipalities of Pozzuoli, Bacoli, Monte di Procida and Quarto and some of the municipalities of Giuglianow in Campania, Marano di Napoli and Naples
