Minoan eruption survey improves volcanic risk assessments NatureComms
), it indicates that the volume of Plinian and Phreatoplinian products has been previously underestimated. An increased volume for these earlier phases of the eruption fits well with the formation of the voluminous Phase 3 tuff cone, which was likely accompanied by significant ash production.Minimum and maximum estimates for the bulk and DRE-volumes for the various components of the Minoan eruption deposits.
Similar caldera collapse and total DRE-volumes indicate an internal consistency.Our total eruption volume estimate of 34.5 ± 6.8 km³ DRE is in line with Pyle’s estimate of 28–29 km³, which, compared to our calculation, overestimated the ignimbrite phase while not specifically considering the caldera infill . Our caldera infill calculation of 6.1 ± 1.
