Session 1.2 GNGTS 2023 Figure 3: Comparison between the results at 1 km spacing and pre-caldera and Neptune Bellow eruptive centers identified by Hawkes (1961) (left). The stars show the eruptive centers of the last three eruptions derived from Baker et al. (1975), Pedrazzi et al. (2014), Pedrazzi et al. (2018) and Geyer et al. (2019). Gray lines contoured in black and white contour the zones of highest hazard identified by Berrocoso et al. (2006) and Bartolini et al. (2014), respectively. Bibliography Abers, G. A., van Keken, P.
