a Square–root of the 1 kg/m2 isomass as a function of the plume height for eruption durations of 1, 6 and 12 h and modes of the Gaussian total grain–size distribution of -1 (open symbol) and 1 (solid symbols) and b corresponding percentage of the total erupted mass comprised within the 1 kg/m2 isomass. Small dots represent values for which the 1 kg/m2 isomass extends outside of the computation domain
