a Total sequence of the 79 CE pyroclastic deposits with each Eruption Unit (EU) reported; distance is 4.5 km from the current crater. b–d Details of the various EUs recognised (modified after9). On top, some of the main EUs inform a regime diagram (crater densimetric Froude number vs. crater radius, for three different eruption column densities) to synthesise the 79 CE eruption dynamics (modified after18).
